New Recyclex interior lining New Duosaf double coil zipper for added security and strength Designed in the USA. Hard outer shell made from strong polypropylene. "Rippled" effect on shell reduces the appearance of scuffs. Expandable for extra capacity. Lightweight frame. Lightweight adjustable aluminium trolley handle lets you move around airports in total comfort. Spinner cases feature four dual multi-directional 360 degree wheels, so you can push or pull your luggage in any direction. Inside the main compartment, a set of elasticised packing straps help you pack. The lid is separated from the main compartment by a zippered mesh curtain, allowing you to keep your luggage organised as you travel. A pocket in the mesh curtain, plus a handy pocket that dangles from the top of the case ensures small items won’t get lost among the rest of your luggage. An inbuilt TSA-compatible combination lock secures the main compartment. A TSA lock works in exactly the same way as a normal padlock, but when you travel in America, it allows security staff at airports to open your bags should they need to inspect them, without the need to damage your padlock or your bag.
