Guaranteed Forever The Vandal backpack features a water-resistant main compartment which can be used in either "roll-top" mode, or in the traditional "flap-down" configuration. A key feature of the Vandal backpack is its ability to quickly double in size from 1,800 cu.in. to 4,000 cu.in. when needed for extra cargo carrying capacity. The Vandal also features multiple weatherproof compartments, urethane coated zippers, weatherproof materials, and a carbon fiber reinforced internal frame suspension system. Front zippered pocket fits most 15in laptop computers or any tablet, a 17in laptop can fit in the rear rolltop compartment. The Mission is where we design, develop, and work in San Francisco. Our workshop was created out of the desire to build gear as tough as it is beautiful. It's this pursuit that has kept us at it for more than 20 years.
