Great day packing and long distance runner
I love this pack. It breathes great on the backpanel and the pockets in the waist belt and the shoulder are great
The side pockets actually will hold a 1 liter bottle on each side as well-for those of us that hate camelbacks/water hoses. My only complaint, as with all osprey packs, is that they wear out under the spring frame on the bottom pretty easily and they are not meant for abuse. And i wish there was two ice tool slots for those odd days when you want an ultralight, small, breathable backpanel pack but will be climbing steep couloirs.
