Brought my g/f to check it out as well, the small fit her perfectly and also agrees on how comfy it was compared to a lot of others. You never know until you try it on... I guess I really learned that lesson now. I like researching everything, sometimes I go overboard and drive myself crazy as well as the people around me. I get it from my dad, were very obsessive compulsive, and like having the "best" stuff. I'm slowly learning that price/reviews are no way to buy backpacking equipment. I mean I know its best to try stuff on, but when I get excited and find something I like I tend to get impatient and forget that little rule. Now I think it sunk in. I would have never bought this pack just because it said Eastern Mountain Sport lol.
