No two trips are the same, and this carry-on travel backpack adapts to the fact. It is accessible from top, side, front and rear via intuitively placed weatherproof zips. The pack meets international carry-on requirements, but expands to 45 L hauler and collapses to a 35 L daypack, making it a great for 1-bag travel. You can organize everything into a range of internal and external pockets, and the main compartment is divisible by a zippered mesh sleeve. Use the magnetic catches for tucking away the shoulder straps and hip belt whenever needed. Exterior is made from weatherproof 100% recycled nylon canvas.
