Big enough, but not too big, for those overnight trips and long treks, the Deuter Futura Vario 50+10 pack gets you through European travels or a day to the cliff. A volume of 3650 cubic inches provides the capacity for all of your goodies, like a hydration bladder and trusty hiking poles that will get you through a weekend backpacking trip. Features like the top-loading construction make it easy to pack the Vario to the brim. Ripstop nylon material shows that Deuter knows what kind of durability you need on your hikes. Control sweaty-back syndrome when you head out for that five-mile jaunt to the talus fields of Chaos Canyon with the Deuter's custom Aircomfort system. This design creates a separation between you and the pack for optimal stability on long hikes and reduction of sweat.
