The small size of the Patagonia Black Hole® Cube was designed to be used as a dopp kit or to help organize small travelling essentials. This rugged little 2-litre bag is made of 450-denier polyester ripstop that has a weatherproof TPU-film laminate and is further coated with a durable water-repellent finish. The simple zip-opening design folds open to a mesh divided main compartment, allowing for the quick organization of things like toiletries. The exterior features a lash-friendly daisy chain and a durable grab handle.
