What Our Gearhead(R) Experts Are Saying: "I've been using the Black Hole 40L Duffel Bag for years as my go-to travel and gear hauler. The recycled ripstop fabric is tough enough for airport baggage handlers and camp dirt, and the backpack straps make it easy to carry when I'm running between gates or hauling to camp."For quick getaways and gear-heavy weekends, we reach for the Patagonia Black Hole 40L Duffel Bag. Built with the same burly recycled polyester ripstop that defines the Black Hole collection, this compact size is endlessly versatile and sized right for airline carry-on. Its TPU laminate and DWR finish shrug off rain and spilled coffee alike, keeping our gear protected on the move. Carrying options make travel smoother-removable backpack straps free up our hands, while the padded haul handles are ready for quick grabs. Inside, the cavernous main compartment holds everything from a weekend's worth of clothes to climbing gear, with an internal mesh lid pocket for stashing smaller essentials. An external zip pocket keeps snacks or travel documents within reach, and daisy chains let us lash on extra gear when we're headed straight to the mountains from the airport.
