Heather S.wrote a review of Osprey Packs Atmos 65 Backpack - 3800-4200cu in on July 1, 2010
This pack proved to be a great, comfortable pack. The pockets and compartments worked great on the trail for easy access. This pack accompanied me for a 12mi hike in the Red Buttes, with room to spare. A note for the size, I ordered a large and should probably have got a medium.
