Love, love, love this pack!

I recently completed a six day hike on Isle Royale and this pack performed awesomely! I have been steadily lightening up my load and tried a Go-lite Jam to save even more weight but I just missed all of the creature comforts of a full-featured pack. I cannot believe how many features Osprey has jammed into this pack while still keeping it extremely light. For me it is well worth the extra pound or so to have places for all of my stuff. As for the suspension, it truly is amazing. I started with about 35 lbs total and I could barely tell it was there. I will say the hip belt was a little stiff at first. I have about a 31" waist and 35" hips so I could use more of a taper in the hip belt but it loosened up after a few days and didn't bother me any more. (One word of warning, if you are a stockier build the suspension might not work well for you. My nephew (football player build) tried this pack on and the corners of the frame were setting on his hips instead of being off to the sides like they are for me.) I was with a scout troop on Isle Royale and we had a few injuries and equipment failures so I ended up packing some extra equipment for a couple of days. I would estimate that I had between 45 and 50 pounds at one point which really pushed the limits of this pack but I can't say it got any more uncomfortable than any other pack would with that much weight. I also did not use a hydration bladder so I did not have the loading issues that some other reviewers have mentioned. I just used a couple of 1 liter Powerade bottles that I threw in the top of my pack and then some 20 oz Gatorade bottles in the side pockets. The side pockets are amazing! They have both a top and side opening so you can put small bottles in them and pull them out on the go. And the stow-n-go feature is absolutely great for holding trekking poles when you need your hands free. And the stretchy back pocket just keeps on stretching and is a great place for all of the miscellaneous stuff you need access to on an extended outing. Sorry to go on and on but I really can't say enough good things about this pack. I looked at and tried out several other packs in the process of deciding on this pack and I am extremely satisfied with my decision. Thanks Osprey for a great piece of gear!

4 night backpacking

I broke this backpack in during my first solo backpacking experience for four nights in south western Iceland. The back is extremely comfortable and fits very well. Overall I was very pleased and surprised with 50 liters I had enough space to get through four nights traveling alone. The many compartments on this bag make things accessible and easy to get to (except for the lowermost part of the bag).

The comfort of this pack is incredible. Aside from normal fatigue one would feel traveling four four days the pack hugs you. It doesn't feel like you're carrying a pack but rather the weight just sits on you. It made hiking up steep inclines very easy and manageable.

However here were some issues I ran into:
The bus driver must have laid my backpack with the straps up on the bus because when I received it back after a five hour bus ride the front elastic pocket had a finger sized hole in it. It's something that can be easily fixed though. Because of my improper backing, the zipper to the right side of the back busted, but was easily fixed by using a fingernail to straighten out the teeth. I think these issues could have been easily prevented, but I just wanted to share my experiences with this pack.

Overall I thought this pack was EXTREMELY comfortable, lightweight, and well worth the investment. Had I not jumped the gun I would gave probably bought the larger 65 liter Atmos, but I do not regret this purchase.

Happy hiking!

Best Pack I've ever owned!

I have only used this pack once (that's my disclaimer). That said, it was the most comfortable pack I have ever used. And I've owned a lot of packs over the years. I think I currently have 6 packs? I've never been compelled to write a review for any other pack.

I steer towards the light and fast / minimalist style of backpacking. With this pack I don't sacrifice comfort in an effort to save weight. It's so comfortable and lightweight. Its a little bigger than many other packs I have used and seems to just swallow up the gear. Its easy breezy to pack.

There are these two use outer pockets. In one pocket I put my tent (Big Agnes Fly Creek UL2) and in the other pocket I put my shell, a beanie and water filter. This constricts the inside of the pack some, however I place my sleeping bag at the bottom and food in the middle. As I consume my food I am able to tighten the outer compression straps, pulling my tent / rain jacket closer to my back. This was a super awesome way of packing.

It was raining and snowing during the four days I was out with this pack, and not having to dig through my backpack to pull out the tent was really convenient. Also, having the water filter and a jacket so readily at hand really sped up our transitions so we were able to cover more ground.

Buy this backpack, the competition doesn't compare!

So far so good

I'm just getting into this so I don't feel qualified to give 5 stars yet. That being said, this is a great pack. Very comfortable, and more than enough room for my gear. My gear is pretty descent (small pack size) stuff so I'd suggest taking this pack home and sticking your gear in it before deciding that it's big enough for you. However, once you get a feel for the pack there's lots of room to be had than appears at first glance.

One tip is to pack the inside cavity first. That will give you enough room to pack the outside pockets without overfilling. I wouldn't put small objects in the side pouches, they have a hole for strap access that could lead to small things falling out of it if you don't strap it down tight. They are better for a towel or something bulky enough to not fit through the hole.

I don't plan on doing too much winter backpacking (yet ;) so 50L is enough for me, but if you're in the market for a 50L bag, You can't go wrong with this one.

Like Carrying Heaven on my Shoulders!

This bag is amazing! It is super comfortable and hugs my body like a glove! I really only have a few problems with it. One is that the hip straps are way too long and practically drag on the ground. The other is that it can be a little tough to load since it has a curved frame. However, I am skinny so, I guess they needed more strap for other people and I can just safety pin it, and the frame is totally worth having a bit of packing difficulty.. The curved frame makes it so comfortable that I barely even need the hip straps! I rarely even use them! I have packed this bag with at least 3 days of gear and barely even felt it on my back! Great bag and would definitely recommend it to a friend.. As a matter of fact, all of my friends want to buy it!
Frankie Z at REI on 01/01/2013

Awesome pack that will last a long time.

Very satisfied! With a full load, the pack wears very comfortable for me and feels balanced, stays centered while on rough terrain. Got it in large, I'm 5'10, and it fits me like a glove. The hip strap is comfortable for me with 25-30lbs, weight rides on my hips. The fabric for the side pockets are a bit snug for my 1 liter Nalgene, but the elasticity and seams have handled very well, 3 overnight trips so far. The straps allow you to compress the pack very well, and have held up to tough use with no signs of wear. The stow and go aspect is a nice feature that I did not care about until I used it for the first time, quick and convenient. I am an Osprey fan for life after this pack!
Christopher at Moosejaw on 04/08/2013
This is a great pack. Easy to organize. The suspension system is like no other. It allows real air circulation, yet maintains stability. I was skeptical, fearing the pack would feel like it was swinging around. I am a woman and own the Aura 50 (women-specific version of Atmos). My brother needed a pack, so I bought the Atmos 50 for him. Both packs will easily support 30+ lbs. Personally, I think if you're packing more than that, you are taking the kitchen sink. I haven't tried more weight. The padding is more than adequate for backpacking for several days. I use one of my Osprey Aura/Atmos packs I use as my Get Home Bag (i.e. 72hr bag). It's durable, yet lightweight. Get one!

I bought this pack for a hike up Kilimanjaro carrying around 15-25 lbs. a day. It worked really well. I liked the adjustability and easy access. I got the L since I am 6'4, and paired it with a medium rain cover from Osprey which fit perfect. One thing I did notice is if you overload the hip pockets it creates a pressure point, so I had to limit these pockets to just a few items. I did enjoy that the side pockets fit a nalgene great and held it very secure. I beat this bag up pretty good this week and it held up great. Looking forward to more short overnights and day trips with it in the future.

Neil Bokemeier at Backcountry.com on 02/28/2012

I own several packs mostly Osprey. This is the pack I use the most. Great for long weekends. Great for a long week hopping shelters on the AT and hammock camping. Just enough room for all my gear and supply for a long 3-4 day hike in 0 degreewinter weather. Plenty of spare room for Spring, Summer , and Fall hiking. The best supension in it class. the compartment are set up perfect with out a lot of extra weight. Only thing if you like to seperate your sleeping bag (and Pad) from the rest of your gear for easy access. Go next model up for seperate zip open bottom. I have beat it up for over a year.

Good pack for a tall guy

Pack was great. Took it on 11.8 mile hike around cold water lake near mt st Helen's, wa and had no problems. 6'5 ft guy and the large size seems to fit nicely. I like the quick adjustable strapping in both the belt and shoulder straps. I loaded it up to about 25 lbs just to test the suspension and it seemed to hold everything in place and was comfortable. Hip pockets are great, toss the point and shoot camera in one for easy access. Great hike and a great pack. Hope to do a couple multi day hikes this summer.
Rock07 at REI on 07/07/2012

Negative Reviews:

I was hoping this pack would be my pack for doing a long thru-hike this summer. Supposedly Osprey revamped this pack from previous years to allow for more weight carrying. Their website indicates max loads from 35 to 45 lbs. Backcountry.com indicates up to 35 lbs. I gave the pack a few trial runs with up to 35 lbs and anticipated going higher.. At first the pack seemed great, but when I went for a 16 miler one day with 35 lbs, the hip belt became unreasonably uncomfortable after about 5 hours. The hip belt design on this pack seems to be a total afterthought in comparison to the rest of the Airspeed suspension design. The hip belt design creates pressure points where the hip belt meets the back of the pack. Otherwise the Airspeed suspension system worked great at minmizing back sweat. The rest of the pack seemed great, but unfortunately for me the pack ended up ebing uncomfortable, maybe because my bodytype is very thin. YMMV

Neutral Reviews:

I took this pack to Zion National Park in Utah. The pack has a steel wire frame around the perimeter for support. An aluminum ferrule holds the ends together at the bottom. The wire digs into your buttocks just below the belt line. After 20 miles you want to throw it off a cliff. When I got it home I tried to flex the wire away from the sore spots and broke the ferrule. I sent it to Osprey who fixed it right away. Good company but this one is a bad design. Whatever you buy, try it on with weight in it first. Kelty is pretty bombproof. I have many packs but nothing so far can beat my Kelty Agile.
