Patagonia decided the wheel was a pretty good invention after all, so they added two of them to their rugged Black Hole Duffel bags and created this superburly, smooth-rolling duffel. Highly weather-resistant, it will protect your gear from rough handling and hold everything you need for an extended trip. Its main compartment is accessed by a zippered U-shaped lid, which has a pair of zippered mesh pockets on the underside to hold small items.
