The North Face Rolling Thunder Medium is one of the toughest wheeled duffles around. It is made from mountaineering grade laminate material so it is water-resistant and super durable. The large main compartment allows you to pack generously and the internal compression straps and top zip mesh pocket keep everything nice and organized. Durable in-line skate wheels, ambidextrous retractable handle and all the carry handles you could possibly want make this bag the envy of the luggage carrousel.
