This burly carryall is inspired by the simple utility of shipping containers on trains. Made from waterproof fabric and equipped with water-resistant zippers and seams, it will protect your gear from rain and rough handling. Its U-shaped lid allows quick access to the main compartment, while two zippered internal mesh pockets keep small items organized. The padded bottom panel adds structure and helps cushion the load when your duffel gets the baggage-handler treatment. Carrying options include removable, padded and adjustable shoulder straps, webbing handles with a snap closure, and haul loops at either end (that facilitate linking multiple bags). Four daisy chains let you lash additional gear to the outside. A zippered exterior pocket holds the stuff you need to access quickly.
