Alberto V.wrote a review of Osprey Packs Stratos 24 Backpack - 1300-1700cu in on November 26, 2009
I mainly used it for commuting on my bike.
it is a very cool back pack, plenty air flow on the back, but a bit strange volume inside, is does not fit a lot of stuff. It is also a bit higher and I can feel it when wearing a bike helmet. Extremely comfortable on the shoulders. I would buy it again.
