Rated 5 out of 5 by from Worth upgrading to 2014 Exos I have a 2012 Exos 58 which I love, however, when I saw the new Exos 48, I thought I would give it a shot. The upgrades are amazing. The suspension, hip, and shoulder pads are greatly improved. I honestly felt like I was no carrying a pack this weekend and I had the pack loaded to capacity. I enjoyed the new exterior cinch down strap system, as well as the addition of the interior load strap. The easily removable top panel and additional panel flap are nice improvements as well. The new loops for keeping straps tidy are a nice addition, as are the new thumb hip belt adjustment loops. This pack is the most comfortable pack I've ever used. Osprey has thought of everything.

Rated 5 out of 5 by from thru-hiked the PCT in '16. Loved this pack! my base weight was a little over 10 lbs and I used this pack (without the lid) for the northern half of a 2016 PCT thru-hike. I loved it. I was using the Exos 58 (a LOT of people used that pack happily the whole way), for the first half but other than the high Sierra, it had way more room than I needed. If I did it again, I'd take the 48 the whole way and maybe just use the lid during the high Sierra bear cannister section. A lot of people had holes develop in the mesh pockets, but if you're careful where you set it down, you'll be fine. I just washed the pack off and after 1,300 miles, it looks brand new. Definitely use a waterproof liner if you'll be in any rain.

Rated 5 out of 5 by from Simply Amazing I have used this bag several times with some long mile days, loading it down with more than 25 pounds and it has performed phenomenally. It's so comfortable with that weight and every feature is just how it needs to be. The hip belts and shoulder straps are enough support, and breathe so well. The Airspeed suspension breathes well too, better than anything I've seen/used. Side mesh pockets are large and easy to use (fit an entire 1L bottle easily). Trekking pole attachment is a great feature. The Flap Jacket is great, I love not needing a large lid when you don't need it. I got the black and it looks great in person. I wouldn't put much more than 30 pounds in this bag though, not sure the shoulder straps could be comfortable with that much weight. I never want to take it off, and I plan on getting the new Atmos for longer trips.

Rated 5 out of 5 by from Great ultra-light pack! This pack is awesome! I'm currently using it on my PCT thru-hike. In the Sierra's all my gear including my bv500 fits inside expect for my bed roll (bivy, air mattress, tarp) which I strap to the bottom on the outside. The bear vault only fits inside vertical, it can not go horizontal. The straps on the bottom are somewhat small, but effective. I have not used the top lid at all. I find that the storage options that it provides are not necessary and I prefer the weight savings instead. The suspension system works nicely. I can put my water bladder where the airspeed back is and increase my storage capacity while cooling my back (think swamp cooler). The pack will help you to lighten your load and prioritize. It carries the weight of all my gear and a weeks worth of food, water, and fuel just fine (around 30lbs for my PCT hike.) For sizing information, use your torso measurement and not your waist. I fall in between a medium and large and found the large to be better due to the torso fitment.

Rated 4 out of 5 by from AT Thru-hike Took this pack on my AT Thru hike, like many other hikers. Almost half the hikers I met were carrying this pack, and for good reason. Light weight, easy to pack, quite comfortable with the trampoline back, even in hot humid weather. Could use more padding on the hip strap IMHO. Top zipper had a tendency to get stuck. Web mesh pockets couldn't stand up to Maines pine limbs that tore them up. True on the weight load, 35 lb comfortabley, and able to carry more with difficulty.
Date published: 2016-03-26
Rated 5 out of 5 by from Outstanding In contrast to the above reviewers, my EXOS 40 is generally loaded well over 30 lb: my loads average 37 lb. The extra weight is due to water: in Australia we have few water sources, so it all must be carried. I've been very happy with the ability of this pack to carry th load: after 50 km or so I get a few black bruises, but this is probably more due to my body type (featherweight) than the bag. The problem is certainly far less noticeable than any other packs I've used. Great mesh pockets that don't get caught up on scrub, excellent harness, nice and light, subdued colour for avoiding attention: all very important things to me. I think I'll stick with Osprey from now on: they make good gear.

Rated 5 out of 5 by from Great Lightweight Pack I used the Exos 48 for a hiking season now, and very pleased overall with this Pack. This lightweight pack and my normal 3 season gear allows me to be under 15 pounds dry, and seldom over 24 pounds with food and water. It carries these loads with total easy and comfort to the point I hardly notice it. I use the size large (over 6'). There is considerable adjustment in the shoulder straps and waist belt that it’s easy to get it “dialed in” for a great fit. The waist belt is quite large, probably could handle 44” to 46” easily. The large rear mesh pocket is really handy for storing a few small things or stowing wet gear to dry out. The side “bottle pockets” are also mesh and pretty flexible, I can easily stow a jet boil in one. There are also some really handy pockets on the solder straps for stowing a phone/gps on the go. If you’re a relatively lightweight hiker (down bag, tarp or tarp-tent, small air-pad, & carefully selected clothing layers) this is a great bag to have. If you’re intending to carry more traditional gear and free standing tents I’d suggesting finding something larger.

Rated 5 out of 5 by from Best pack I own For loads of less than ~45lbs or so, look no further. It weighs nothing, holds everything, and compresses extremely well for day hikes or summits. The hip belt pockets are excellent and hold quite a bit. With a full load and hydration bladder, the trampoline back touches the pack. Kind of nice if you've got cold water in there. Durability is excellent so far, but keep in mind this is a lightweight pack so it should be treated more carefully to make it last. The only thing I'd change is to remove some of the extras. The shoulder strap compartments and ski pole holder don't really add anything.

Would you recommend this pack for someone doing some extended traveling across Europe or Asia while not planning on doing a lot of camping?

Asked by: ppritch2
The Exos 48 is a great lightweight pack, however it is probably not the best bet for extended backpacking trips. While based on personal preference, packs with a gear capacity between 70 and 85 liters are usually a better option for extended trips.

I am planning to walk the Camino de Santiago de Compostella next september.  Would the Osprey Exos 58 be an appropriate pack for this 33 day trip

Asked by: ddoyle
Whether or not this pack will be big enough depends on the gear you are anticipating to carry. If you have relatively lightweight, compact, updated gear and you will have food stashes along various checkpoints on the trail, then you should be just fine with this size backpack. If your gear is bulky and you have to carry all of your food for the entire trip, you might be better suited in a larger capacity pack in the range of 60-75 liters. If you would like recommendations please contact us.

Does this pack have the same "antigravity" support the Aura offers? Also, this pack is listed as "unisex." I am 5'8", 160lbs and have boobs that I need to consider when buying a pack. Will this pack work or should I stick with the women-specific Aura?

The Exos does not have the AG – antigravity suspension. This pack may work for you, but the Aura AG packs will probably have a more comfortable fit.
