Choosing the right volume pack is crucial for maximizing your adventures, considering factors such as activity, kit requirements, and future trips. The Osprey Arcane Duffel offers a 30-liter capacity with flush pockets and a bottom pouch that can be opened to use the full internal length of the pack. It also features a large front mesh pocket for damp or dirty belongings after hiking, as well as an external zipped pocket for storing items.
Volume is calculated cubically using width, length, and height, but backpacks tend to be more cylindrical in shape with rounded edges. Lash points are available on the pack’s exterior around the center pocket and on the top of the lid. Ice axe loops are also attached to the back, and a bear canister can fit between the pockets.
The Osprey Arcane Duffel has no water bottle pockets, but its stretchy exterior pockets hold more volume than any other. The hip pockets on the sides are large, and the small, stretchy pockets on the outside are also spacious. The pockets are flush to the bag and the bottom pouch can be opened to use the full internal length of the pack. Even the external pouch is tight and flush to the pack, so only 1 or 2L if being generous.
The Osprey Arcane Duffel includes two decent-sized zippered pockets, which add to its organization. Some backpacking pack makers count the main compartment and all exterior pockets when calculating pack volume, but Osprey does not do this. The Exos backpack has a large top lid with a decent-sized external zipped pocket and a smaller internal zipped mesh pocket with a key clip.
The Aether Plus/Ariel Plus has two extra external front pockets and a top lid that converts into a day pack, offering higher volume options. The rear shove-it pocket is a good size, but it does not constitute a separate pocket.

Is 55L too big for carry-on?
The size of a backpack that can be used as a carry-on is not a general rule, but most domestic airlines typically allow 50-55L packs to be used if fully packed. However, if the pack has a curved frame or exterior pockets are fully loaded, the 50L may be pushing it. On the other hand, a 55L+ pack with a slim frame, not packed to the gills, and compression straps can squeeze it in. For example, a Big Agnes Sun Dog 45 can be carried on several flights, even on smaller planes with smaller overhead bins.
When measuring the bag, pay attention to the height of the frame portion, as it cannot be compressed or smashed down. Small planes usually have smaller overhead bins, so it’s important to consider the size of the pack when determining its capacity as a carry-on.
Where do I find the size of my Osprey backpack?
The OSPREY pack size measurements are as follows: 38 cm (15–21 inch), 46–60 cm (18–24 inch), 33–43 cm (13–17 inch), and 33–43 cm (13–17 inch). These measurements are designed to ensure that the pack effectively distributes weight throughout the female body, thereby ensuring optimal performance for the 25-year warranty period.
Does backpack volume include pockets?
Backpack volume is typically measured by adding up the total volume of closed storage, including the main compartment, pockets, and hip belt pockets. However, smaller manufacturers may use a different method, including open pockets like side water bottle pockets or rear mesh pockets. This can make weight-to-volume comparisons misleading.
Hiking daypack sizes range from 15 liters to 35 liters on the high-end. A smaller 15-25 liter backpack is usually sufficient for 1/2 day hikes, but a larger 25-30 liter pack is recommended for all-day hikes or winter trips to carry extra water, food, clothing, and emergency gear. Hip belts are often not necessary for backpacks under 25 liters, but they are essential for backpacks carrying over 20 pounds in gear weight.
Hydration packs are also a good option for daypacks, but ensure sufficient volume to carry extra clothing and gear, as they can take up considerable space. When comparing packs from different manufacturers, it is important to contact the manufacturer to ask about their method of measuring backpack volume.
How is backpack volume calculated?
To determine the capacity of a backpack in liters, measure its linear dimensions (height, width, and depth) and multiply them to get the volume in cubic centimeters or meters. For example, if the backpack dimensions are 0, 60 cm, 0, 33 cm, and 0, 22 cm, the capacity can be calculated as 0, 043 m³ or 43 liters. However, this method is approximate as it assumes an ideal rectangular shape and does not consider external pockets or material characteristics.
How is backpack volume measured?
The conventional approach to calculating the volume of a backpack entails the application of the following formula: The volume of a backpack can be calculated by multiplying the length (L), width (W), and height (H) of the backpack and then dividing the result by 1000. This method requires the use of a measuring instrument such as a tape measure or ruler. In order to ascertain the volume of the backpack, it is necessary to measure its length, width, and height.
Alternatively, these measurements can be obtained from the manufacturer’s website and used in the following formula: Volume (in cubic centimetres) = Length (in centimetres) X Width (in centimetres) X Height (in centimetres).
What are the measurements of an Osprey?
The osprey is a unique bird of prey with equal length toes, reticulate tarsi, and rounded talons. Its outer toe is reversible, allowing it to grasp slippery fish with two toes in front and two behind. The osprey weighs between 0. 9-2. 1 kg and 50-66 cm in length, with a wingspan of 127-180 cm. It is similar in size to the largest members of the Buteo or Falco genera. The subspecies are similar in size, with the nominate subspecies averaging 1. 53 kg, P. h. carolinensis averaging 1. 7 kg, and P. h. cristatus averaging 1. 25 kg. The wing chord measures 38 to 52 cm, the tail measures 16. 5 to 24 cm, and the tarsus is 5. 2-6. 6 cm.
The osprey’s upperparts are a deep, glossy brown, while the breast is white, sometimes streaked with brown. The head is white with a dark mask across the eyes, and the eyes have golden to brown irises and a pale blue nictitating membrane. The bill is black with a blue cere, and the feet are white with black talons. The osprey has a short tail and long, narrow wings with four long, finger-like feathers and a shorter fifth. The sexes appear similar, but the adult male can be distinguished from the female by its slimmer body and narrower wings.
How does Osprey measure backpack volume?
The Odyssey uses 20mm plastic balls to fill the pack, filling all components to their extended capacity. The volume of the pack is measured using a volume measurement cylinder, which is more accurate than cubical measurements. The pack’s shape and size, which are more cylindrical with rounded corners, make it easier to measure the volume. The cylinder is then placed into the pack to ensure accurate measurements.
What size is the Osprey 40l?
The Farpoint Family is a lightweight and practical men’s backpack designed for fast-moving globetrotters. These packs feature technical backpacking features like fine-tunable torso adjustments, load-lifting LightWire frames, and breathable harnesses/hipbelts. The internal organization is optimized for travel purposes, and rugged compression straps keep the carry tight and stable. The Farpoint 40 is sized to meet most domestic carry-on requirements, making it the perfect one-pack-does-all for streamlined travel.
It features an adjustable torso fit, large panel zip access to the main compartment, lockable sliders on the main compartment zipper, dual front compression straps, large front shove-it pocket, external zip toiletry pocket, padded top and side handles, a stowaway backpanel, harness, and hipbelt, and a quick access zippered 16″ laptop and tablet sleeve. The pack is lightweight and durable, with durable fabrics in high-wear areas and smart design to create a durable and lightweight travel pack that will last a lifetime.
Can you take a 50l backpack as carry-on?
The Knack team recommends using a carry-on backpack size under 50 liters, which allows for easy portability, skip lines, and cost savings on checked bags. A 45-liter backpack is recommended for carrying more items. All Knack Packs are carry-on friendly, under 50 liters. On most jets, a backpack can be used as a personal item under the seat if it’s under 20 x 12 x 9 inches. However, some airlines have larger or more restrictive personal item allowances, so it’s crucial to check your airline’s website to ensure your backpack counts as a personal item. Small and Medium Knack Packs fit under the seat on most jets, even when expanded.
How to choose Osprey size?
To determine the correct pack size, measure from the iliac crest to the C7 vertebra and reference the torso length below. Osprey Xenith, Xena, Aether, Ariel, Atmos, and Aura packs offer interchangeable shoulder harnesses, which should terminate 2″ to 3″ beneath the armpit when at the proper torso length. The webbing should not touch the side of the body below the padding. Women’s packs are designed with true function, comfort, and style, with over 20 years of experience.
How to measure an Osprey bag?
In order to ascertain the length of the torso, it is necessary to identify the iliac crest, which is the superior aspect of the hip bone, the C7 vertebra, which is situated at the posterior aspect of the neck, and the large protruding bone at the base of the neck.

I never looked back after switching to the Exos 48. It carries the load like nothing else whilst remaining lightweight. I always called BS when they touted on about their ”’suspension back system”’ but lord almighty they weren’t spewing nonsense! It’s honestly one of, if not the comfiest pack I’ve ever worn!
The thing with Osprey packs is even though they’re a lot heavier than your average UL pack, they also tend to be way more comfortable. I’ve found that the frame and suspension and their anti-gravity system help mitigate that extra weight and allows you to carry a lot more stuff with a lot less discomfort, and the straps are really thick and padded and comfortable. If you’re the kind of backpacker who likes to hike in luxury and bring a chair, a roomy two-person tent, real food with cookware like skillets etc, then these packs are the way to go. Even if you have a more minimalist setup, the suspension on these packs will make you feel whatever weight you do have less so than other packs would. For instance putting 20 pounds of stuff into an UL backpack and 20 pounds of stuff into an Osprey backpack and trying them both on will usually reveal the Osprey pack to be a lot more comfortable. I also tend to use all the extra bells and whistles. The provided rain cover has kept my stuff dry in heavy thunderstorms before, while the brain is where I store things I might need quickly such as my first aid kit, lighter, and my warm clothes in the wintertime. The hydration pocket for a camelbak is also pretty nice and the mesh on the frame allowing air to cool your sweaty back is a must-have imo. For reference I use the Atmos 65.
An osprey atmos 65 was my first pack 5 years ago, and it’s the same one I use today. There is a lot of extra weight and unnecessary organization, but I love the pack. It’s incredibly comfortable and adjustable and there is no wear. I have no desire nor need to purchase a new backpack, so it saves me a lot. I don’t understand how you could actually hate the pack, even with every opinion you listed, but to each their own. I will gladly continue to enjoy my time outdoors because of my atmos.
The reason the Exos 55 seems bigger than the Arc Haul 60, is that Z packs includes the capacity of all the pockets in their number. Most manufacturers list only “covered” compartments in their volume. Open pockets are unmeasured additional volume, since you can put bigger items that stick out in them. Exos has 55L in the main compartment + brain. Stretch pocket and side pockets are unmeasured additional storage. Z Packs arc haul 60L is 47L body, 8L stretch pocket, 2.5 each side pocket.
I commented on one of your other articles but this should have been the one to comment on. I own this pack and love it. One signifcant modification, however, makes it much better if not perfect. My inspiration is the Gregory Focal 55. On that pack side compression straps may be routed hidden/inside the stretchy side pockets allowing compression at same time giving full use of stretchy side pockets even under f 7:28 ull compression. Problem with the Exos is the compression straps are permanently on outside of side pockets creating a real use problem when pack is fully compressed. What’s more is the bottom side compression side is couple to/attached to the hip belt. My experience with this pack proves that this coupling s unnecessay and by decoupliing the compression strap from the hip belt results in more comfort and better function of the hip belt on my hips and then with a couple small 1/4″ slits in ripstop fabric, a few hidden stitches plus super strong waterproof fabric glue, I have rerouted compression straps to under/hidden/inside stretchy side pockets. I also detached the upper compression and moved it. Now I have full use of stretchy side pockets and large front stretchy pocket even while the pack is under full ccompression. Water bottles and other items go in and out without a struggle whatsoever. Or even run longer items inside of side pockets yet still under comoression with full functional use of stretchy side pocket such as a water bottle beig put in or taken out without messin with the compression.
I’ve been waiting for this UL craze to come full circle on backpacks. I figure it’s only a matter of time before people realize that ‘traditional’ packs were designed for backpacking and will offer the best experience. Stripping down frames and necessary load bearing features is backward engineering to when packs were just a bag with straps. It’s ironic that backpacks started simple and eventually evolved to what marketing has now convinced people is a ‘traditional’ (outdated) design.
I love my Osprey pack. It took me thousands of miles across Europe, probably hundreds by foot. It was a great investment and quite durable. I am an athletic, stout guy and don’t mind that it’s not an ultralight backpack. I wanted size and features and quality construction and it delivered. It’s ten years old and just as good as the day I bought it. Osprey would be my first choice for my next pack should I ever need one. I just really loved the way it took an enormously heavy load and spread it across my body in such a way that I didn’t really notice the weight.
I have one of the previous models of this pack and can definitely recommend it. There are somethings that I like better with the new version (hip belt pockets), but there are some things I like on the older model (more user friendly buckles, easy to remove brain, that kind of thing)… just preference but I’d still recommend it. Only wish it was water resistant.
Recently purchased Exos 58 took it for 8 days, 7 night traverse of Isle Royale National Park, mid-August 2023. It did over all very well. However, a part of the frame broke, along the very bottom where it curves around the small of the back. Only issue with the break was that it caused a constant creaking sound with each step. I did overload it, max carry weight is listed as 35lbs. I had 41 without water. 47 pounds with water. Good thing is I bought it from REI and can return it. Will I buy another Exos 58? Quite possibly, but will explore other options comparing each to all that I did like about the Exos 58.
Osprey is ubiquitous in the UK as we don’t have as much choice when it comes to backpacking brands. I tend to avoid them but I’ve recently purchased the Exos 48 (non-pro) as it cuts the nonsense. I’ll be testing it next week but I like the look and feel of it so far. The suspension system and the ventilation it provides seems worth a little bit of extra weight.
Went for the Aether 65l – very nice pack though a little on the heavy side. Had the Exos Pro in hands, too, but what bothered me was the compression straps running across the mesh side pockets; you can either compress your pack on the side or you can access the contents (e.g. a water bottle) easily in that case. Mutual exclusive which is a bummer… Ah, and I like the front access to the main compartment on the Aether…
I have an Osprey Talon 11L daypack and I fell in love with it the first time I used it. My partner and I hiked a trail that has a portion that requires rappelling down some pretty steep inclines on ropes and then 6km on very sharp rocks to a secluded cove. A well balanced pack is necessary for sure footing as if you wreck an ankle you’d need to call the coast guard in before the tide traps you. (Bay of Fundy, highest tides in the world) and on the way back as soon as we climbed back up the ropes we were hit with a severe thunderstorm (wasn’t in the forecast). Deafening thunderclaps and heavy rains and the inside of the pack stayed dry (with my Nikon DSLR in there too). had some dry clothes in my dry bag and wasn’t expecting wet weather at all so learned a lesson for next time. Also I realized it was missing a piece for the stow on the go trekking pole feature and just emailing Osprey lastnight I got a reply in less then an hour that they were preparing to ship me out the part soon (my first time using a warranty like this) I would love to get a Stratos 36 or 44 as an overnight or weekender. I only dabble in UL so the pro versions are a bit too rich for my blood but I would certainly try Osprey again. My only complaint is that the cool Osprey logo wore off so fast. They should really embroider them or something.
While I think that a lot of Osprey packs are overkill and overweight for their use case, I do recognise the areas where they do well: 1. Their “all-mighty guarantee” (even though this is officially non-existent in Australia) 2. Their range of kid’s packs. As someone with small hikers in tow, I particularly appreciate the ability to give them a properly fitting pack to carry their own gear. 3. The Poco. Going back in time, I had to carry those same small hikers, and the Poco was my vehicle of choice. The rigid arms either side of the child’s “cockpit” seating area meant that it didn’t collapse when loading a reluctant tiny human.
I have a Hyperlite that I love, but it leaves my back wet from sweat. I recently bought the Exos 58 for the fact that it stays off of my back during warmer backpacking trips. I had a hard time finding one that really felt like it “belongs” on me, and am still not quite happy with the fit, but my back feels so much happier. The pack fits everything I need and is completely comparable to the Hyperlite. And yes, I was nodding when you were talking about the compression strap, which is marvelous on the Hyperlite. The Exos has it’s own methods of compression, but nothing like the Hyperlite.
I think Osprey makes great packs for what they are. Are they UL? Generally no. But if you like extra pockets for organization and/or carry heavier weights they make packs suited for you. Also, their warranty is among the best in the industry. I still have an Exos 58 that was my primary winter pack until I recetnly moved up to a Superior Wilderness Designs Long Haul.
I have a Ren65 that runs just under 5lb. Packed I am hauling right a 40lbs. I use it as a day pack and come in at around 15lbs without my sleep system and food. Clearly, I am not a UL hiker! I’m a 5’2″, over 50, overweight, female hiker. Finding anything that actually fits is a challenge. Osprey’s adjustable everything works well in getting the pack fitted and comfortable.
I have the Exos 58 and tried the Exos Pro in this article. The Pro has a thinner frame and less rigid suspension. This all resulted in the weight being carried too much in the shoulders. I returned it. If you haven’t tried the latest Exos 48/58, you don’t know what you’re missing! Yes, it weighs more than the Dyneema rucksacks, but it’s easier to carry and you’re less sore at the end of the hike.
I got hooked on Osprey years ago with my Xenith. Cavernous for long trips, comfortable, easy access. Sold it to a kid hiking the AT. I just bought a Atmos 65. The waist belt is tighter than I like so I’m looking to swap it out; but I got it at such a good price, I had to buy it. Your pack looks good so thanks for sharing.
A great review as always! I tried to move away from my Osprey and tried a Mariposa 60. On paper the Mariposa is an awesome pack however for me there one huge problem in that without airflow between my back and my pack I really struggle. I just could not get comfortable with the Mariposa. In my experience, when it comes to packs, lighter is not always better, the key is comfort and weight transfer to your hips.
I have the AURA AG 65. What i love in Osprey backpack is the suspension system and the top notch ventilation on the back. Even if they are already heavy empty, they are very comfortable. But! I hate the belt pockets! Hope they change that in the future. They are way too small to fit cell phones or even my small Sony RX camera! If i don’t need a pack for heavy loads or if i’m not hiking in winter with bulky stuff, i use my new favourite pack, the Durston Kakwa😍 I used the 40L and i just purchase the 55L
Thanks for the review! Though, I’d put my Gregory Optic 48 on before I’d strap on my dusty Exos. IMHO Gregory has better comfort in the shoulders and waist, zipper hip belt pockets, and a stretchier (is that even a word?) back mesh pocket. I was sad when they discontinued the model and changed it to the “Focal”. Which for some reason is not as good as either the Exos or Optic.
I have the Osprey Atmos 50 4.5 lbs but super comfortable. This pro you got caught my eye a few days ago. I also just bought Durston Kakwa 40 and going to use it this weekend under 2lbs. Now I am looking at the Zpacks Arc Haul 60 as it internal volume is similar to the Kakawa 40!! ironically. So I will either be getting the Kakwa 55 30oz. or the Arc Haul 60 @22oz… any ideas one which one?
The features on Ospreys (specifically Atmos in my case) aren’t unnecessary. They just have a place and time. Unfortunately for most of us “serious” hikers the Atmos/etc are just a pain in the ass. Though they are perfectly comfortable. I love the brain for the fact that I can keep things there which I need quick access to, but my god is it a royal pain to remove/re-attach all the time and I hate how it kind of “dangles” there at the top. I know it’s attached tight and won’t move but it just bothers me. One of its biggest issues is that getting your water bottle out of the pockets with the pack on is damn near impossible unless you have one of the shortest Smart Water bottles. The zips are impossible to operate on the pockets with one hand too, etc. It definitely has some issues but 98% of it is good but just doesn’t work well for us as it could even if it is a damn good pack. Hopefully Exos fixes a lot of those issues.
Your comment on the weight of Osprey packs how “its not uncommon for them to be 5 lbs or more” is unfounded. Only one of the packs in thier line of hiking packs is in that range. The Aether/ Ariel are for heavy loads for people doing serious trip like Denali or other trip that require lots of heavy gear and food. That comment is a bit deceiving . I’m glad you like that pack though. I do too.
The changing mind of something is a good thing and important for personal views. Spiritual Christian thinking changes every time and it grows in development. Its a backpack which holds many resources and tools. But nothing works unless we practice using these tools and keeping our backpack comfortable and carefully use it so it remains in good condition.
At age 70 with a taste for long hikes (400km, 2 weeks upwards), ultralight is a requirement not an option. I’ve been using an Osprey Atmos 50 (mostly without the brain) for several years and really like the comfort and the antigravity system. However it does weigh 1.850kg and I’ve been wondering about a pack to bring that weight down some. Looks like this could be the one!
Not an untralighter, kind of a hybrid. (Summer load includes a Granite Gear Crown VC pack, a Henry Shires Notch tent, a Z-rest, and a what-have-you sleeping bag that I’ve had for twenty years or so.) “Light and fast” isn’t really my style. I love my Osprey Talon day pack – all of the little attachment points exactly fit the gear that I usually rack in the winter, and the suspension is comfortable. I ‘m just OK with the Granite Gear pack for my overnight pack. It’s not the best, but someone gave me an REI gift card and I needed a new pack, and that year I couldn’t find anything better in what they carried at the time. If I live long enough to need another pack, I’ll certainly look into Osprey again.
Trditionnal pack might not be for yyou, but its is still good for 85% of hikers. People who are not into ultralight, will prefere these pack do to resistance, confort and how much you can load them with heavy stuff. the Osprey Aether is good but I still think that the best Osprey pack is the Atmos AG. Best confort and loading weight you can have on the market.
I definitely won’t use it with the brain. 3 oz is a lot for anyone who cares about weight. I use top lid of my Exos 48 only in winter when I need more room for winter gear. Also I took off / cut off some useless straps (including the red one) to reduce the weight. This new backpack looks like a promising upgrade and a way to reduce the weight. How durable is Exos Pro backpack fabric? Is it more durable or less durable then Exos series fabric?
I have the previous generation of the Osprey Atmos 65 AG, and have a core weight around 20 lb, and will tip over 30 when carrying food and water. I love the idea of the Exos Pro pack however, I love my side vent and bottom and entry zippers too much and can’t justify saving 2lb to give up those features.
Complete opposite of this pack, but thanks for the recommendation. Seen the aether plus 85 at rei the other week. Went in to get it a few days later and it was gone. (entire inventory sold out) . Moose jaw was the only one to have it in stock, was able to get it for 140$ off with the sale and code. Arrived 4 days later with free shipping. Usually use the atmos ag 65 but for longer trips, climbing gear or bringing my son along, the extra space is nice.
Ospreys are the most comfortable load carry packs I’ve ever used….and I’ve used a lot of them since 1973. I am going to clarify this situation for those less experienced folks perusal this so they don’t get the wrong idea. If you’re going out on a longer trip….you’ll be carrying more weight…the ultra light packs are not well suited for this because they’re not designed to carry heavier loads comfortably maybe 30lbs or so. Packs like the bigger ospreys are designed to comfortably carry loads up to about 60lbs or so. The extra 2 or 3 lbs is well worth the weight believe me….the correct way to understand this is for lighter loads you can use these lighter packs just fine and for trips that have heavier loads stay away from the gram counter packs….they will be very uncomfortable. The bottom line is if you do short and long trips….you should probably think about having two packs for each type of trip if your interested in cutting as much weight as possible.
I’ve used a Zpacks pack but ended up swapping it for an Osprey Kestrel 38L because all those dyneema fiber packs (Zpacks) are very slippery against clothing. So the Zpacks tend to slide downward putting weight on my shoulders. It doesn’t seem to matter how tight I get the waist straps. Despite Osprey being made of heavier material, it’s shape conforms to the curvature of my spine and also has lots of rough surfaces that help it stay in place against my back. Because of their unique design features Osprey are my most comfortable packs (I have several, lol) which also allow me to carry heavier weights comfortably. I also have one of the older Osprey Exos packs but still find the Kestrel more comfortable and better at trabsferring weight to my legs. I couldn’t carry more than 20lbs in my Zpack before it became uncomfortable. With my Osprey Kestrel 38L I can carry 35lbs comfortably for 16hrs a day no problem.
Interesting you mention the compression strap on the inside as a downside. After a year of use I now specifically like that about it and I’ll explain why: With the tradition straps you compress every single thing in your backpack and there’s no real way to use it when you carry something that doesn’t do well under compression (fragile souvenirs, some foods, etc.). With the Exos Pro I can still compress most things, but pack the stuff I don’t want to compress on top of it.
I will NEVER have another backpack without ventilation. EVER! ZPacks are not substantial enough to handle heavier loads. Additionally they are subject to problems with the arc system. Gregory has a version of ventilated suspension but it is not as good as the Osprey. The easily removable brain is another greater feature of the Exos. Q I can fit, just barely, a BV550 horizontally inside at the top of my Exos 48, which has worked fantastic for longer extended trips of seven days or more. Too many ultralight packs will barrel unless they are packed just right. And I have used a lot of various ultralight packs and always return to Osprey.
Nice review man! My first day hiking pack was a osprey stratos 24. I loved that pack!! The trampelene back is second to none! Until i tried severe ultralight gear then i realized how much i missed their trampelene mesh back panel. Although alot of other osprey packs dont compare to the stratos trampelene back. They seem to have shrunk the seperation overtime on the back mesh? I do like this new exos 55. The brain of these packs are a handy feature. I say that too cause i noticed alot of people who use ultralight roll top packs still find themselves without enough room. So before you know it gear is filled every exterior pocket and some even have gear dangling off the pack somewhere. Seems thats where alot of ultralight packs fail. I want the pack im using to hold all my gear without gear hanging off the pack too much. Only thing i would like to see osprey do is use premium pack materials like Robic nylon, dyneema, X-pack, ultra pack. Maybe even design their own roll top pack but keep this new trampelene style back and frame suspension. Not sure if that crosses over Z-packs patents or not but would be very nice to see. Or i would like to see an update Levity pack made with better materials and offered in more subdued color ways. White is just tough to keep clean. Good stuff man! Hike on!!
I agree the packs are heavy, but that is true for all traditional packs like Gregory, Deuter as well, also ultralight does not really handle heavy items all too well. For that a more traditional pack just works better. I’m not surprised Exos works so well as it alongside Atmos and Stratos always been the most comfortable packs due to their TMP of the Osprey line. Aether that you shown has always been a mediocre pack with a mediocre suspension system and to much going on it,, Exos, Atmos and Stratos are more simplistic although latter two are still on the heavier side. Osprey doesn’t really do ultra light, just as all other traditionalist don’t either, so it’s a bit of an odd complaint, as there still many for whom ultra light will never actually work like carrying bear canisters, photographers who do overnights and other needing to cary more big heavy gear, also all the traditional I had could take up some absolute brutal beating, I wish I could say the same about the other stuff. So it’s all about horses for causes.
I have a 5 year old Osprey Atmos 50 and I love it. The suspension and the mesh is what makes it for me. Also the bladder compartment with the little strap and clip is well thought out. It does weigh in at 4.5 lbs but it sure is comfortable and functions well enough that I don’t feel the need to get anything else. Cheers
I went from a Kelty Coyote to a ULA Circuit. While I liked the extra pockets on the Coyote, for organization, I’m okay with the trade-off for the weight savings. And despite the Coyote having decent ventilation, suspension, and adjustability, the Circuit is just more comfortable to me. But the main thing I miss is the brain. I used it for storing maps, my electronics (in a ziplock), and pretty much anything that goes on my head (hat/beanie, bandana, buff, headlamp…). It was just nice knowing where those things were and having easy access to them. It’d be kinda cool if someone like ULA designed a light/waterproof brain that could be purchased separately and attached to their packs.
I’m a rookie ‘packer looking for comfort more than UL. I don’t know that I’ll ever pack more than 3 days so a bit of extra weight won’t matter as much to me. I definitely want lighter gear, but as of right now, weight is never better than 3rd priority for me. And really my priorities are a balance of cost, “good” and weight
I just recently picked up an Eja Pro 55 – the ladies version of this pack – to replace my Eja 48. I love the pack with the exception of the hip belt pocket (which you mentioned) and how much of a pain it is to remove the brain. Osprey saved a bunch of weight by removing zippers, pockets, and clips on this pack, but sacrificed a bit of convenience. Overall though I’m pretty pleased. One thing I wish Osprey would do is provide clip adapters with their packs so we can turn the brain into a fanny pack.
I bought the Osprey Exos 55 Pro a few months ago and love it. I agree with your points except for having an open hip pocket. I do actually like having one zipper and one open. One additional complaint: i wish the hip belt pockets weren’t so far back. This pack is extremely comfortable and fits my gear extremely well (even better than the hyperlite). I compared the hyperlite and really wanted to keep hyperlite but three things that i couldnt get over: 1- for some reason hyperlite straps hurt my shoulder even after trying different size packs, adjusting straps, and adjusting the frames. 2- water bottle access. While i can access my smart water from hyperlite pockets, its much easier with the exos 55 pro. 3- hyperlite=sweaty back. My main concern with the exos pro 55 is durability. Time will tell but im skeptical on the material durability and how small the hip belt clip is. I would have gone for zpacks for a backpack but they are just too expensive as i never see them on sale like i do with the two other packs mentioned above.
The fact it still has that flap is enough for me to not bother going back to Osprey. It may be a user thing, but I find the brain pocket to be more of an annoyance. Maybe I am doing it wrong, if I only put gloves or my rain jacket in there… But I usually kept a med kit in there and it just flopped around against my head/neck. I’d rather have an oversized belt pocket or low profile side pocket. Next pack I get is either a replacement Hyperlite or the Kakwa 40. I did enjoy my last Osprey’s back ventilation though…
Many commenters seem to be confusing the Exos to the Exos Pro…the Osprey pack you have reviewed here. I have tried a Zpack, a Durston Kakwa, and the Gregory Focal as well as the Exos. Th Exos and Focal were the most comfortable, but not light enough. Then I tried the Exos Pro 58 and bought it. After a couple of mods, without adding any weight to the pack, my Exos Pro 58 is a FANTASTIC pack. The modifications were to the compression straps…moving them under the side pockets matching the functionality of the Gregory Focal. The Exos Pro is very light and way more comfortable than the Zpacks or the Kakwa.
That pack looks great. I really like my Osprey Rook, but it lacks the front pocket, removable brain… and the side pockets aren’t the greatest. I usually carry around 30 lb… my only hesitation would be going from a 65 to a 55 L pack. I just don’t know that I could get away with going that much smaller… maybe some day. 😁
I’m a proud user of EXOS 58(not a PRO version) good things – first of all, it’s designed for guys, the ladies version is called EJA, so it just fits great – as a result, the suspension is just fabulous indeed – adaptive back length – compartments are really functional suspicious things – gets wet in no time and rain cover is not included – recommended load 11 kilos, when the load is about 15 kilos the backpack starts bouncing on your back – in some time it will start to make these squeaky sounds
It’s cool that you have sponsors. I’m sure the appreciate you as well. And. Personalized message is friendly and authentic. I am still torn between backpacks I like 30 litres and try to be minimal but the whole big bear canister is not going to happen very well in it. I like Osprey great quality and the fo have lighter packs to offer. I get the whole bells and whistles of all the extra straps and the internal strap doesn’t seem to do much and it is awkward for compression. Too much to fix in the field as well. The material that I spray uses is solid and durable I do like that about them and I do feel like the packs are comfortable at the lower weights. I find that in everything in life unless you make it yourself and even then it might be not just right or perfect. You have to sacrifice it seems, something you may or may not like in one pack at or another. Is there truly a perfect pack. I like darker colors if they offered a darker color and that pack I would consider it right now the finances are tight but I do like osprey. I am dabbling in an ultra-light minimal survivalist everyday carry primitive Carry styles. And other thing about the buckles or anything that removes is in my opinion as a Creator or designer of things I like if it detaches, to have extra juices. So like a lid that fold out into a larger square to make a map to sit on or to use as an extra poncho or kilt. Or turn it into a pack liner. That way you could use it in another way in the field and not have to leave it at home.
Two trips with this pack for me and I’m happy enough I’m with it. Less back sweat than any pack I’ve ever used and comfortable enough when the load isn’t too heavy. I agree on the brain it’s generous size and can fit a lot. Combined with the side and back pocket and hip belt it’s good amount of storage for various things.
So I’ve never been hiking, did allot of camping as a boyscout. Doctor say I need to do more exercise now that I’m no longer working. But walking around the neighborhood is just plain boring . So I’ve been trying to find affordable hiking gear . Seems every youtuber has the best of the best. And that’s hard to do on a budget. I appreciate the time you take on reviewing products that would otherwise be over looked as they don’t fit in today’s high end styles. That every youtuber has to be seen with. I know the essentials that’s important to take . But the back pack is a conundrum to me. I don’t mind having a 30lb pack to start to get in shape and be in nature. To start I’m not looking to morph into a knife only bear grills in 2 years . Either but would be nice to have a decent pack and gear to get out there while saving for better gear down the road.
Good review article. I own the Arc Haul Ultra and it does not have a 60 liter internal capacity. The internal capacity, per the Zpacks web site, is 47 liters. So a head-to-head comparison of internal volume is not valid. That said, it is a comfortable and extremely well made pack. I attempted to carry a BV 475 inside the pack for a week along a portion of the JMT last Fall. The pack bulged and eventually the frame stays fell out, leaving me with a frameless pack. Poor headwork on my part and not a pack problem.
I don’t understand why ultralighters are bragging about extra 150gram in that Exos Pro (a much more proper hiking pack) and stick to the overrated, overpriced, and (sorry) ugly Zpack? Having a trade-off for 150gram for much more comfortable backsystem is much more logical vs losing 150gr for an uncomfortable zpack. I feel like using a slightly >2 pounds backpack is a major sin for ultralighters. Another thing: complained about unzippered left hip pocket, but then also complained about excess zipper on the other part of the pack. I just don’t get it.
I usually pack ultralight… still rocking an OG Zpacks ArcBlast that is still holding up great. With packraft season upon us, I think this Osprey pack may fit the bill to carry that extra weight around. My wife and daughter are getting into backpacking this year and have been very happy with their Osprey packs thus far. The last time I carried a traditional/heavier pack (an REI 65L) I was descending down to Snowmass lake, just like you were @3:34! BTW, those coolers do look great, I may have to check them out.
I mean, I would rather pay 400 dollars for an osprey than for a dynema tube… I can’t believe people will pay so much money for this UL crap. Even a basic dynema TARP is 400 dollars!? the most basic shelters and packs that are the same if not MORE expensive than other competitors. Just hike more and strengthen yourself. Sure too much stuff defeats a lot of the point for me but I would rather have a few extra pounds and nice stuff rather than paying 2k for a kit that will rip at the slightest pressure and has no features.
Unnecessary features? They are optional. Don’t buy it. Continue to use your ZPacks pillow case with straps. Your choice. Now I’ll make your UL head REALLY explode. I carry nothing but Mystery Ranch…never less that 65L and usually an 80L Terraframe version. I also don’t usually hike 20 miles in a downpour so there’s that.
Several years ago I went from the heavy Osprey Atmos 65 to an ultralight Hilltops Pack’s 45 liter Raven. I sacrificed the comfort of the framed system for the knee saving weight of the frameless pack. Now this is an interesting compromise – possibly. I think I could reduce my gear weight to compensate for the extra pound between this Osprey and my Hilltop’s model. As I check gear for an upcoming very long thru-hike, this may be worth the try.
I have the Gregory Focal 58, which I think is “inspired” by the Exos? But the compression strap is over the main compartment, not under like on the Exos. Comes in at 2lbs 11oz. It has a brain. My top requirement on the new pack was back ventilation cuz I’m a sweaty boy …and this pack checks that box and many, many others.
My first pack was sort of similar to the Osprey Exos 55; it was an REI flash 45; a little smaller and a little heavier, but very much the same concept. It wasn’t a bad pack I like my current pack (a superior wilderness designs ultralight long haul) a lot better. It’s 3/4 of a pound lighter, 10L bigger, made of higher quality materials, and fits me better being custom made. I do kind of miss having a brain on my pack for miscellaneous item storage, but I think some ziploc freezer bags will solve that problem.
I’ve been using Osprey packs for 6 years now, I have 6 and love them for how comfortable they are and how they handle a load. But last year I bought 2 Granite Gear packs, a Crown2 60 and a Crown2 38, and have to say I like them at least as much. The GG 60l can’t carry as heavy a load comfortably as my 50l Osprey, but keeping it under 30lb it’s amazing. I’ve had the GG 38l up to around 22lb with no comfort issues. They have all the features I want and none I don’t, the fabric is very water resistant, and they even come in colors other than the same old black, blue, green, and red! My pottery clay/rust 60l looks awesome!
I know I’ve had great experiences with smaller, ultralight day-pack style packs and agree that their bigger packs often have great suspension but are a bit needlessly complex, which is why I haven’t looked to them for larger volume daypacks, for instance. So it seems like this REALLY fits that hybrid design language and plays to both sides of their strengths. I can definitely see that weird compression strap situation being a minor but regular irritation, but seems worth trialing for personal experience.
I bought an Osprey Exos Pro 55 and can say it is quite comfortable for me, while weighing half of what my older traditional packs weigh. No regrets. Lightweight daypacks tend to have poor back ventilation so I might just take the brain off for dayhikes. The Zpacks Arc Haul is probably the closest competitor and is lighter but also more expensive (I haven’t tried that one).
I have an older exos I got at a garage sale, my biggest issue is that it’s a medium, and I really needed a large, so it doesn’t carry as well as it should. Aside from that, I have noticed it doesn’t perform well over 30lbs, which is a weight I struggle to get under with my loadout. From what I see of the new pro model, I think it might be perfect.
I would try it; although. my “Go To” pack’s an exsturnal-frame 100L Alpine Freight Pack. Works well for me; regardless of activity I can pack all my gear in; I find it easy to use; easy to carry, and is very comfortable for me. I’ve had other packs, and two Alpine. I’ve had the other one you talked about in this article, and your right it won’t fit a bear canister, but I do a lot of camping; fishing; hunting, and hiking in bear country here in Canada. Thank you for the article
I’ve got an Osprey Aether that is more or less my camera equipment / bring the warm heavy sleeping bag, bag. I’ve also got a Granite Gear Crown 2 60 which I’ve used on most trips. I would love something between the two with a better back fit than the GG pack, not sure if I want to shell out Osprey dollars for it though lol.
I love Osprey, well what they started out as. Lightweight, small, clever. the 9L drinking bag they came with 10Y ago I still own and love. But their bigger bags are like many American products, just bags without structure. But you can’t beat their weight savings and quality. You cannot say Osprey’s are heavy dude. It’s not a UL-product. It’s just very light in all the other categories. I do agree so incredibly well on Osprey having unnecessary zippers, straps and things on them. It’s like they actually don’t know what the customer need are.
I’ve Owned many backpacks over the years. Lightweight, heavyweight and in between. A few years ago I purchased an Osprey Aether 70 AG for winter backpacking. The Osprey Aether 70 AG has become the only pack I use. The Osprey Aether 70 AG fits so well and carries so well that I don’t notice I’m wearing a backpack regardless of weight.
I had the exos 58 2022 model. Didn’t like it at all. Too much junk in there and uncomfortable shoulder straps. I’m sure others may have a totally different conclusion but I’m going to a frameless Bonfus 38L and going more UL. Doing something like a thru hike with a heavy arse pack is terrible in every way.
Have you ever considered showing off a KS Ultralight pack? Just got my KS60, and WOW it’s a great pack. For being probably the lightest full sized framed pack out there (mines 67Lish and around 1.42lbs “framed”), it’s weird that you’ve been silent on them (unless I just have missed you mentioning them).
I’ve used conventional high volume packs all my life because I hate attaching things to the outside of my pack. That said, I want to rethink things in terms of weight when I do the PCT and want a much lighter pack. 55L would likely be too small for my liking, and with long food/water carries, a max of 30lbs would be less than I’d be seeking. The Arc Haul 70L looked promising, but what you just showed regarding the bear can scares me on that pack. I find it very difficult to hone in on the right pack for my once in a lifetime epic hike that’s upcoming.
One of my packs is an Osprey EXOS 65 or some such… It was 4.5 pounds but (gasp!) I took a a knife to it (as I’ve done to all my packs over the years) and shaved off a pound. (ice ax loops, water bladder pocket and such) Now I use ultralight gear from Six Moons and what not so have this Awesome, well ventilated pack for light loads AND, A bear can fits inside with no issues.
My favorite backpack – about 25 years old – has this type of mesh suspension, so I’m definitely interested in these Osprey offerings… though I’m inclined to look at the Exos 58 because it solves one of the problems you have with the 55 Pro *both side pockets zip closed (**and I can save $30). I’ve stated before that I’m a truly traditional backpacker, with over 50 years of experience, and I don’t like to spend a lot on gear, though lighter weight gear is becoming more appealing as I get older *and it becomes more mainstream (in design and price). I am not willing to sacrifice comfort for weight, in most cases, which is why I’ve not made the step to an ultra-light backpack, yet.
With all due respect to your sponsor – Moosejaw is great. The day those dingdongs at osprey get it right I’ll eat my shorts…they are addicted to form. Seemed to have gotten the weight right but only without a feature. Theres still too much “other” which means I would have less usable space. I feel like I know this just by looking at the front pocket (I won’t even mention the hip belt) they can’t stop themselves from using that shiny heavy cool looking fabric with stretchy sides. HORRIBLE. They add restrictive webbing that makes it even less usable…because everything gets synched down and compressed. Maybe its me but I’ve never used a compression strap…there just there. I tighten them up for looks. When Osprey gets the pocket right then they’re mind will be in the right place. Again, I’ll never understand the need for a larger pack for a bear can. I have a 30 liter pack body and it carries all the bear vaults easily with a full loadout for big trips. nothing strapped to the outside – folks are just taking too much stuff…like a chair or bedding like home. I would like to know though re: the suspension. Was your back sweaty at the end of the day or was it dry. Peace all
Good job with this. I’ve had five Osprey packs over the past eight years or so. The only two I have now are the Kestrel 38 for winter and the 48 for backpacking which handles cans well. Reason being is each of the others had suspended back panels which developed mind-numbing squeaks in the peripheral frame. And I don’t overload. The Kestrels are definitely a weight suck, that I try to shave elsewhere, but it’s worth it to not deal with squeaking. Maybe it was just luck of the draw, and wouldn’t happen again, but I’m not sure I’ll take the risk.
Thanks for the review! We have a hiking trip on the JMT in August and I am up in the air on this pack. I know a lot of people lean towards the ultralight packs on this trail, but my full load will be around 15-18 pounds, so I am at a crossroads as to which route to go (ultralight or this pack). Comfort is honestly the most important thing to me, and that might sway me towards this pack. Just wanted to know your thoughts on this. Thanks for the article!
Osprey’s are great until the PU inner coating starts going off after a few years. Oh what a mess. One long afternoon and it can be scrubbed out, but the packs would be lighter and more long-lived for those normal people who wouldn’t scrape it out if they just left out that manky PU. Excellent review as always!
I have recently bought the Exos 48 to shed weight from carrying the Atmos 65 which is about 2lbs heavier, but the Atmos blows the Exos out of the water in terms of comfort, its far superior with the thicker padded hip belt and thicker shoulder straps. The Exos straps feel sharp after a while and I am constantly “jostling” the pack to get a comfortable position. My opinion is a bit more weight in the pack is well worth the extra comfort. Besides which the Atmos can be modified to shave off a few ounces.
I think you are kinda wrong on this one. Its not the best. Original last year Exos 58L 1.3kg is much better and totally worth extra 300g. Ive used in to walk coast to coast John Muir Way in Scotland and few other hiker and just used frameless 3F UL backpack to compare and im going back again Exos is that good. Nothing beats it in how comfortable is and how put together it is. They missed a mark on Pro if few aspects and made it actually worse. It would be awesome with few other tweaks but anyway I dont this they would listen to us simple people commenting. Hope you try 2022 version one day and see to compare.
Dear Steven, I have to get this off my chest. I loved your article’s. Especially Take a seat. I show it to everybody. I have a YouTube Premium account, so I don’t have to watch advertisements. And now I notice that with EVERY article that you are putting out, when you start with the words, “this article is sponsered by”… I hook off…. I am so sorry… Is there a way you can change that??
I’ve been using the Exos 58 for years now and it’s a great pack for my needs. I started out with a Kelty Coyote 80 and that 5 and a half pound monster destroyed my back every time I took it out. After purchasing my first Osprey pack, a Stratos 35, I fell in love with their suspension system and really wanted a larger pack that offered more storage so I could take it out on longer trips, but not as weigh as much as the old Kelty. I’ve flirted with the idea of getting an ultralight pack, but I’ve really never needed something lighter than the Exos. Also, every time I tell myself I’m going to go out without the brain to see what it’s like, I ask myself “where am I going to put my head lamp and sawyer?” then end up leaving it on.
as a 6’4, admittedly heavy then I should be backpacker, I am constantly struggling to find gear that 1. fits comfortably, and 2. doesn’t add a bunch of weight. I’m glad to see these “in-between” bags. Large enough to carry my gear, light enough to offset the increased weight my larger tent/bag/pad add. And have a suspension system to carry it all comfortably.
As someone who sufferschronic fatigue and pain the suspension and lightweight has me sold, i’d add a zip or velcro to that left pocket so that phone or gopro doesn’t fall out if I fall forwards. Other than that it looks good, darker green or brown options would be nice Osprey. Love all your articles and work you put in, thanks for the Nikwax article did all my gear last two days 😊
I’ve been using Osprey packs for 37 years. I have 6 Osprey Packs now. But then again, I’m not an “ultralight” weiner snob. My average packout weight is 30lbs. And I’ve never whined or griped about it, no matter the distance, terrain, or weather. Glad you tried out this one despite that fact that you ” HATE Osprey. Pretty strong words for a company that’s never done you harm.
Sounds good, with a lite back pack that has extra room I might be able to carry a tent and sleeping bag that is not meant for back packing and then I would not have to spend money on something only to find out it’s not for me, I know the bear canister was required but was it necessary did you see any bears
They’re definitely heavy but on the other hand I see people do the PCT and half of their time is spent fixing stuff that breaks on their fancy ultralight packs. I have a hard time breaking osprey packs. osprey packs DO need to look closely at what others are doing. Their hipbelt pockets are terrible.
I don’t know if this is a disagreement or not, but in my belief you have a misplaced belief that light weight is more important than comfort. I’ll gladly add an extra couple of pounds to a pack if it’s more comfortable. And if the pack is light weight without being ultra light, but still comfortable (like the Exos/Eja packs), great.
I’m so shocked that the bear canister fitting was the plus! I tried one out at home and returned it. The bow in the back to allow a gap for ventilation worked great for that but got in the way of gear. I may have had a different one. It also wouldn’t stand upright and the straps were soooooo convoluted.
I have the Exos 58. A bit heavier: around 250 grams (as I am from the metric brigade). But with zippers on each of the belt pockets. Wouldn’t trade it for a real UL pack as the comfort is really high (higher than those UL packs) and I do have to carry 15 kilo (approx 33 pounds). Can really recommend it. Only thing we find annoying sometimes are the compression straps on the outside of the pack. The placement of those make the use of the two side pockets a bit cumbersome sometimes. So if the Pro would have been out when buying my pack I probably would have bought that one. But now I am a happy camper (literally) with my Exos 58.
Stephen I’ve bristled at this before, but calling full-frame packs ‘traditional’ really undersells the innovation and persistent improvements that are being made to the designs, especially in areas like Suspension (which you touched on) and biomechanics. You’re obviously entitled to your preference for lighter weight designs, but I wish you’d call them ‘full-frame’ or something that doesn’t implicitly position them as retrograde and conservative.
I used a Osprey technical alpine pack i purchased back in the 70’s. I didn’t know of osprey at the time I just liked the pack. I used it for everything, school, hikes and light weight 1 or 2 day trips. I guess it was about 29 sq inches internal. but it finally literally fell apart. I was still very impressed. When my car was broken into and I lost my North Face pack, i went with a osprey. Your right, they are on the heavy side but I still love the quality
Lol. My pack is a dutch military Lowe alpine sting pack that’s supposed to weigh 6.6 pounds. It’s not light but it’s bomb proof. It’ll outlast any ultralight pack and I’m sure any Osprey as well. I’m getting the Haven safari tent hammock at just over 12 pounds. I’m definitely not an ultralight hiker, lol.
Throwing it out there; I have a Bonfus pack, and I like it a lot! But for some added comfort that I can easily put on or remove, I grabbed a Ventapak attachment. It is this lightweight spacer that goes between the user’s back and the bag; creating space or a gap for airflow – they are less than 1 lbs in weight, which I know is still a stretch for gram weenies, but I like that it can add variety in comfort for different bags that depending on the wearer may want more air flow on their back. If someone struggles with sweat on their backs after purchasing a pretty expensive bag, the Ventapak attachment may be worthwhile at not a terrible price or weight! Also after looking at some reviews for the Ventapak, they have had older issues with some of the clips not being up to snuff, BUT reviews have consistently stated that the company sent replacements as needed and have since updated the buckles in their newer Ventapak products to limit the weak buckles. So another good company to support <3
