Big enough, but not too big, for those overnight trips and long treks, the Deuter Women's Futura Vario 45+10 SL Backpack 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 sweat 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 moisture.
