The Summit series of packs are some of the easiest to like in the Frost River line. “It’s all you need”, has been said. Just put stuff inside, throw your shoulders through the straps and go. No need to meticulously pack contents… It can be stuffed and you can be on your way. The Expedition adds side pockets that will carry a 1L water bottle and a front pocket to stow small items. It is all you need and a little extra.
