Super durable and fully submersible, the Osprey Transporter Waterproof 70L Duffel Bag is a workhorse gear hauler that can hold up to the elements on both land and water. An option for kayak campers and rafters, the duffel is fully waterproof when closed, thanks to a double TPU coating and waterproof, YKK Aquaseal zippers. The removable suspension system doubles as a shoulder strap and married backpack straps, allowing for additional carry options beyond the oversized grab loops at the duffel's ends. Multiple lash points on the exterior make it easy to anchor the bag to our truck, roof rack, raft, kayak, mule train, or alpaca—whatever kind of adventure we've got on tap.
