After hiking over 3,000 miles this year with the Atmos 50, I can attest to the quality and durability of the product. Like all Osprey packs, it takes a day or two to break in the shoulder straps, and then youre good for a decade. I think its funny how outdoor gear sales people try to convince would-be customers that packs like this cant handle the needs of extensive trips. Well, leave the canned food and the blue jeans at home, and youll be fine. I love this pack. You get the best of the internal pack with the breathability of an external frame. If I could have any pack in the world, for long-distance hiking, it would be the Atmos 50 I already have. Sure its dirty and has a few small dental floss and duct tape patches, but the pack has no major issues and has treated me well.
