Got this for use as a travel pack (carry on) or extended day hikes where you need the extra room. Seems thought out quite well and fits like a glove (very comfortable). I am male, 5'8" and 165 pounds if that helps you to size it. Plenty of pockets to stow kit in and the on-board rain cover is a nice touch; zippers always leak otherwise. The two side pockets have "pass through slots" between them and the main body of the pack to allow one to carry longer items as needed. Could be handy. I've used another Kelty pack (Redwing I think) in the past and it was good too. Kelty pack prices tend to be lower in general, but not their quality. No complaints. I believe that this pack will serve me well for my intended use. I have spent a long time crawling the WEB looking at packs (many, many of them) and this seems like a great deal. Also, Moosejaw rocks. Very quick delivery. Very quick.
