The mid-sized Black Hole 55L duffel bag is highly weather-resistant, stubbornly tough and 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 lost items like earbuds and a 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. Carrying options include padded, removable shoulder straps, webbing handles with a snap closure and haul loops at either end for linking multiple bags. Daisy chains let you lash additional gear to the outside. Made from burly, 900-denier 100% postconsumer recycled polyester ripstop with a TPU-film laminate and lined with 200-denier 100% recycled polyester with a polyurethane coating. Both fabrics have a DWR (durable water repellent) finish.
