Big enough for the minimalist traveller, this 30 litre (expandable to 38 litres) backpack has a modern design aesthetic with a utilitarian focus on function and usability. Side compression straps help manage volume. Two side expansion bottle pockets lay flat when not in use. A zip away shoulder strap system converts the backpack to a large briefcase style bag. An interior hanging pocket and sunglass holder add more function along with a separate laptop compartment. The Mountainsmith Continental Backpack.
