The NOMATIC Laundry Bag keeps your dirty clothes organized. At your destination, expand the bag and use the hanging strap to attach it to a door knob. Once the laundry bag is full, fit it easily back in your bag, keeping your dirty clothes separate. The NOMATIC Laundry Bag is designed to fit perfectly in the shoe compartment of the 40L Travel Bag. (Every 40L travel bag comes with a laundry bag included, for all other bags you must purchase separately.) Size/Weight: 11.5" x 6" x 1.5"/ 1 lbs
