The smaller, more versatile cousin to the 21 and 24, the Urban Assault 18 is the perfect daypack for your urban adventures. This 18L 3-Zip backpack is constructed with high-tenacity 500D Cordura fabric and YKK zippers, so it will be tough enough to stand up to all of the obstacles in your way. With a floating padded sleeve to fit your laptop, a document compartment, interior dump pockets, external bottle holders, and a full-length HDPE frame sheet, you’ll be able to carry all your crucial gear to traverse the concrete jungle. Inspired by military rucksacks, the Urban Assault 18 is a nimble, rugged choice for your everyday carry, both on and off the grid.
