Familiarity: I've put it through the wringer
This is my first of the newer construction style of camelbacks, and it is WAY easier to use then the old ones. The bladder opens easier to fill, and slides in and out of its sleeve way easier. Otherwise its what you'd expect if what you expect is quality and enough room to carry the essentials and have a little room to spare as the seasons change. This is a great pack to have if you want to leave your tool kit and tube in one pack that will work for riding the monarch crest (32 miles at high altitude) or quick laps on the local trail.
