This suitcase is designed to be extra-lightweight and expands to allow you to pack more while still enjoying the rigid structure and durability of a hard case. Closure: The two-way zip-around closure features two low-profile integrated TSA-approved locks with replaceable pullers at the top of the case for easy access. Exterior features: Protective bumpers accent the streamlined silhouette while adding to the built-to-last nature of the case. The three-stage telescoping handle and four spinner wheels provide stability and ease of maneuverability.
