Piorama Adjustable Bag

The incredibly versatile Piorama Adjustable Bag, available in six colors, is an innovative duffel that riffs on the iconic 1950s U.S. military bag. The big difference with this near half-the-weight offering (1.4lbs) is that it expands from a 31-liter to a 62-liter bag (with a 46.5-liter option in between) and can be easily converted to a backpack thanks to some added straps.
