This large Black Hole Duffel easily swallows a week's worth of stuff. Highly weather-resistant and stubbornly tough, it protects your gear from travel and rough handling. The main compartment opens via a zippered U-shaped lid, which has a pair of zip-closing mesh pockets on the underside for easily misplaced items like your headlamp and phone charger. A zippered exterior pocket holds all the stuff you need to access quickly. The padded bottom panel adds structure and helps cushion the load when your duffel gets the baggage-handler treatment. There are padded removable shoulder straps for a backpack carrying option, 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. Made from 14-oz 900-denier 100% postconsumer recycled polyester ripstop (22% solution-dyed) with a TPU-film laminate and lined with 3.3-oz 200-denier 100% recycled polyester with a polyurethane coating. Both fabrics have a DWR (durable water repellent) finish.
