We have previously reviewed the Osprey Aether and Atmos backpacks and found their feature set much to our liking, but their weights pushed our upper limits, and we could barely call them "lightweight." Osprey is solidly re-entering the lightweight backpack competition with its new Exos pack, which is a brand new pack series specifically designed to be lightweight. The Exos packs will be available in spring 2009 in 34, 46, and 58 liter volumes.
