Feather lightweight yet extremely durable top grade polycarbonate ABS hard shell materials for maximum impact resistance. The polycarbonate allows the shell to absorb impact by 'flexing' when under heavy pressure. 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. Features an internal retractable aluminum dual-tube telescopic handle with push button system. State of the art 360 degree spinner wheels, allow effortless maneuverability even when the checked cases are loaded up. Features a spacious main compartment with full interior lining, top and side carry handles for easy lifting and deluxe interior features include a garment compartment & side zippered pocket. Available Colors: Silver, Black. minimize
