What Our Gearhead(R) Experts Are Saying:"I took the Mission 100L Duffel Bag on a multi-week alpine expedition, and the Seamless Folded Body construction genuinely holds up better than anything else I have used at this size. At 2. 2 pounds, it disappears into your luggage on the approach, and the lockable zipper feet gave me real peace of mind through multiple cargo transfers."Expedition logistics have a way of humbling even the most seasoned alpinists, and the gear you trust to hold everything together needs to be as serious as the objective itself. The Black Diamond Mission 100L Duffel Bag was designed with that reality in mind, stripping away everything unnecessary and doubling down on the features that actually matter when your bag is getting dragged across airport floors, lashed to pack animals, or thrown onto a pulk sled in the dark. The Seamless Folded Body Construction eliminates the seams along the bottom and ends where traditional duffels fail first, and the 900D recycled PET Ripstop fabric resists weather and abrasion without adding bulk. At just 2. 2 pounds, it is one of the lightest expedition duffels available at this volume, a number made possible by building the entire bag from a single polymer material that also happens to be fully recyclable at the end of its life. A straight YKK #10 zipper with lockable feet keeps the main compartment secure through every leg of the journey, while the combined webbing bail handle converts to a shoulder strap for the long hauls between base camp and the trailhead.
