Review on Osprey Packs Atmos Abyss Backpack: The Ultimate Casual Daypack by Jon Thompson

Excellent backpack. Cobwebs on the back keep you cool on your hikes, while webbing provides ample support around the waist and chest. I would suggest trying on each backpack in person (I did this before purchasing from REI) to get an idea of whether it will fit you and how comfortable it is. This bag has an adjustable frame for tall people (I'm 6ft 1in and it fits great). There are pockets on the lumbar belt that can fit a variety of things. I've worn this with a water bladder and the comfort/space was still great.
