Spinner luggage provides the utmost mobility and maneuverability for today's travelers. It features four, multi-directional wheels that rotate on two axes, thus providing a 360 degree spinning capability. This makes it effortless to pull or push, which lessens the strain on the body. In addition, it will stand upright, even when open, making packing and unpacking trouble-free. Many styles have interior hanger hooks for wrinkle-free transportation of clothing, as well as compression straps, lined pockets and removable mesh pouches. Spinners are available in various forms such as a hard exterior version, with a shell made from a material like polycarbonate, a soft exterior model, made from various materials including vinyl, canvas, nylon, leather and polyester, or a soft exterior variant that is combined with a steel frame. Corner guards, typically made from a textured or rubberized material, act as an extra layer of protection from wear and tear. Spinner bags with a locking mechanism provide additional security for checked bags.
