I love Heys luggage. Just love it. Not only do they offer amazing color and pattern choices in their full line but cases such as these are extremely resilient, "popping back" to their original form when pressure is applied or they're traumatized by baggage handlers.

The Xcase-XL is the world's lightest luggage set, a blend of Polycarbonate and ABS mixed into the shell makes the Xcase-XL extremely durable .

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 .

Push button mono handle system and special chrome plated inline wheels have metallic ball bearings that allow the case to glide effortlessly . 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 . 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' .

This lightweight luggage set is definitely your best choice of luggage as it allows you to pack more . Each case has a combination lock.
