The Aviant Voyager 65+10L Backpack is Deuter's largest pack built for traveling continents for weeks or even seasons. Its 65L capacity expands to 75L to accommodate goodies purchased around the globe as well as about a week's worth of traveling accessories. The cushy Contact back panel and sturdy steel frame feel like a backpacking backpack built to handle trekking from Swiss town to the nearest trains taking you to Paris. When you reach the train, the Aviant's shoulder straps, hip belt, and back panel all stow away to stay safe for compact packing. The removable daypack has enough room for what you need in the trolley, as well as day trips to museums and cafes. A full-zip opening on the front panel allows easy packing and unpacking.
