Here is my pack, I have used a couple different one, easily the most functional and most comfortable one I have worn.
Im 6'2 - relatively wide shoulders and chest, somewhat narrow waist. Its great for the type of hikes I typically go on - 3 night excursions. The waist belt for me is probably the most important feature of this bag, its crazy comfortable and has 2 pouches on the belt to keep things like a camera or snacks.
I combine it with a 3L Osprey water pouch that I carry along with it. So far its taken me to 13 overnight trips in Canada, 1 in Utah and 1 in the Grand Canyon.
