Lochrane G.wrote a review of Osprey Packs Atmos 65 Backpack - 3800-4200cu in on August 1, 2011
I have used this pack to travel the U.S. as well as on the AT.
It does it all, and comfortably too.
-Lots of pockets
-Great weight distribution
-Comfortable even with 40+ lb's
-Water bladder fits great
-Easy to break down for cleaning
-Def worth the $$$
