The 70L Black Hole® Duffel features an easy-to-access main compartment for stowing away a week's worth of stuff, removable, ergonomic shoulder straps, and a zippered pocket can be accessed from inside or outside of the bag and, when empty, acts as a self-contained storage system for the whole duffel. Patagonia's Black Hole® bags are made from 100% recycled fabric that is extremely durable and weather resistant.
