I have this (coyote color) and the 40L version. This is a great pack. I have used it for summer UL overnight wilderness trips high in the Rocky Mountains. It’s a bit small for extended or cold-weather treks. The suspension system is great. I know packs well, own too many, and tired of the UL frameless packs’ (e.g. GoLite) lack of support. Cinch the belt on this pack well and it’s almost weightless. This is worth the added weight. I added pockets to the waist belt, for convenient access to frequnetly needed items.
