Osprey Packs Atmos 35 Overnight Backpack - 1900-2300 cu in

I was looking for a backpack that I could carry-on to plane and use for a two-week trekking trip to Thailand. The air-flow back was very appealing because I sweat alot and Thailand is quite hot and humid. The problem was the arc in the frame was a concern though when cramming it into a overhead. The arc also made it more rigid so you couldn't stuff it as much. I really hated to, but I ended up returing it and wound getting a Osprey Kestrel 38 which looks like a better fit for my purpose and I got a few extra L's of space. My wife got a Osprey Talon 44 which is even better for carry-on travel. Very light and alot of room and still makes it in the carry-on restrictions. Osprey is a great pack and they are a great company. We called them and they were extremely helpful. One other thing...they are supposed to be improving the Atmos next year so it should be even better.

My daughter urged me to get this backpack because she loves hers so much. I have just returned from a trip to Switzerland where my husband and I spent 9 days going from place to place in the mountains, over passes, etc. We carry everything for the entire trip in our packs and stay in hotels at night. This pack was terrific. We have done this kind of trip for many years and I have never been more comfortable carrying my gear. I would highly recommend this pack.

Sized just right for an every day pack. Light weight, fits great on my back, and lets my back breath easily. Love how it sinches down so tight, hate packs that are so bulky, even when mostly empty. I use this pack as my day pack and take it everywhere with me. When I am on an outing, I use my Osprey 65, it's twin, just a whole lot bigger, but just as comfortable.

This pack is great for any day adventure you can dish out. The backpanel and suspension are comfortable, they carry loads well, and the space not being used in the back panel can be used to carry your hydration bladder. With accessories for all sorts of outdoor adventure, the Atmos is a great pack for those looking to get outside.

osprey packs are so super comfortable and look so cool. search no more. this pack is a perfect size for even long backpacking trips if you are using ultra light weight gear. and did i mention that this pack is SO COMFY!?

I have owned the Atmos 35 for over a year, and must have used it over 50 times (without ANY wear). The comfort afforded by the airmesh backpanel has the ability to make loads of almost 30 pounds feel like nothing. I started by using it for dayhikes, and there was more than enough room for my stuff, but the compression straps keep it tight and snug against your back. The hipbelt pockets are a great for snacks, camera, etc. The axe loops and ripcord clips can be used to carry trekking poles very securely. I moved on to overnight trips, and to my surprise, found that there was enough room for everything -- including my Mountain Hardwear Raven 2 tent! The packed performed EXTREMELY well on several overnight trips. I have used my Atmos for longer mountain biking excursions when I need more room than my camelback could offer. Indeed, I found it to be more comfortable than the tiny camelback, despite being capable of holding about 20 times as much, even on a long bumpy ride. Now, into my second winter, I am finding that the pack works impeccably for snowshoeing (I found a way to strap snowshoes using side pockets and axe ripcord clips!), and its close conformance to the body make it great for backcountry nordic and touring applications. I went on a trip to the White Mountains two weeks ago involving 12 miles of x-c skiing in the woods while carrying snowshoes and lots of other gear. I could have asked for a better-functioning pack for that trip. I also found the pack to perform incredibly well during alpine climbs in the Presidential Range. Everything about this pack rocks. Those used to the traditional "tube" pack may be perturbed by the curved backpanel, but believe me -- the space of 35 liters is there -- you just have to get used to packing a little differently. The attention to detail is all there, the materials used are so light and so durable. My 2 pound Atmos doesn't have a scratch after a year of HEAVY use. Oh, and I should mention -- it is still the most comfortable pack I've ever put on my back!
