The Deuter Quantum 70 + 10 is a load-hauling beast designed to handle anything your travels throw at it. Whether you're about to embark on a two-month Eurail trip or you're going to spend a year circumnavigating the globe, our Top Pick for Extended Travel will almost certainly meet all of your travel needs. This pack's name is deceiving - the Quantum actually holds 90L of gear (body = 70L, brain = 10L, and daypack = 10L). Even though we weren't looking for the best backpacking backpack, we loved using this pack for multi-day backcountry adventures and loved using it to carry mass amounts of gear. We were looking for the best travel pack on the planet and this one has some sweet features that land it pretty high in our lineup. It is super comfortable and has plenty of space for all your stuff.
