This multi-liter backpack will take you everywhere from a day on campus to camping in the mountains: combining high-quality, sustainably sourced materials and thoughtful design with premium functionality. Unlike any other 4-in*1* pack out there, this one is designed to give back to humanity by bringing environmental sustainability into every decision about production and consumption, including how it’s manufactured, what materials are used at each stage of the supply chain as well as its impact on animals, people, forests and waterways.
