The Patagonia Black Hole® 40L Duffel Bag is perfect for small loads and long weekends and meets most airline and train carry-on requirements. This duffel bag is made from a burly recycled polyester ripstop with a highly weather-resistant TPU-film laminate and a DWR (durable water-repellent) finish. It features a top zipper that allows the bag to open wide for quick access to the entire main compartment and, when empty, the duffel stuffs into its own pocket for compact, self-contained storage. Its padded, removable shoulder straps let you carry the Black Hole® Duffel like a backpack and can be detached when not in use and the reinforced haul handles withstand over-zealous baggage handlers. The Black Hole®'s zippered side pocket can be reached from the outside or inside of the bag and a mesh interior lid pocket keeps essentials organized and close at hand. The Patagonia Black Hole® 40L Duffel Bag will become your go-to for any travel or activity.
