The XCase XL is the worlds lightest luggage set. A blend of Polycarbonate and ABS mixed into the shell makes the XCase XL extremely durable. Push Button Mono Handle System. Go cruising in styles as the case-XL has these special Chrome plated wheels. These inline wheels have metallic ball bearings that allow the case to glide effortlessly. The Polycarbonate allows the shell to absorb impact by 'flexing' when under heavy stress. The ABS is then added to give the shell greater rigidity so that it will not permanently deform when under pressure but instead 'pop' back up into its original shape. The wheels have a large 85mm diameter for greater durability as well as 70mm chrome plated rims to protect the metallic ball bearings from the environment. These wheels are located on the outside edge of the luggage to provide greater stability and control when rolling over rough surfaces which would normally make your case 'wobble'. The case-XL is the lightest set meaning now with the airlines becoming more and more restrictive on allowable weight, this lightweight luggage set is definitely your best choice of luggage as it allows you to pack more. Dimensions: 30" x 20" x 12"; 26" x 17" x 11"; 20" x 14" x 10". Available Colors: Black, Silver, Powder Pink.
