Whether you're beach hopping in Vietnam, hopping subway turnstiles to catch the last train, or trekking along the Nepali coast, the Marmot Trans Hauler Backpack has your back and your gear. This heavy duty daypack carries 28 liters of stuff: tablet, laptop, DSLR camera, a couple of guidebooks, water bottle, energy bars, some apples, and a wad of cash for bail money. If your adventures are slightly less stressful and more along the lines of a fall picnic on Cape May, ditch your electronics and use the space for a bottle of wine, glasses, baguette sandwiches, and fresh oatmeal raisin cookies. Made from 420D high density nylon, and supported with a removable webbing waist belt, the Trans is a transcontinental, transatlantic beast. This pack shrugs off cement walls and burly branches alike, and the D shaped opening turns this sleek pack into a yawning chasm of space.
