The new Modular Travel Bag System from FirstSpear uses the the Rolling Bag Frame. There are a couple of components available of various sizes and they can be combined to offer a custom luggage solution. The bags slide over the frame and connect to one another via Tubes. Available in Black, Coyote, Ranger Green, Manatee Grey and Blue.
