Say 'howdy' to the DC Saddleback Carry-On Bag and its 23 liters of vacation-enhancing volume. Made from cotton canvas with ripstop nylon, the Saddleback features an aesthetic inspired by outdoors-style backpacks. But you can tote your city-slicker laptop in the suspended laptop sleeve and carry your water-bottles in the stretch side pockets. A secure harness system complete with padded waist belt eliminates swaying and the sternum strap features a built in whistle lets you sound off in case you're lostAAAor just want to make noise.
