Our smallest Black Hole(R) duffel meets most airline and train carry-on requirements. Tough and highly weather-resistant, it keeps your gear protected and easily accessible. 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 your lottery ticket. A zippered exterior pocket holds all the stuff you need 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 for a backpack carry, 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 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.
