Made of a tough but flexible rubber material, this Cotechs bumper is built to last, features moulded on/off and volume keys. Designed specifically for the Sony Xperia Z3, the bumper offers wrap-around protection from minor damage without impeding access to any of the phone's functions. All buttons and ports are still easily accessible while the bumper is on the phone. Due to it's flexible nature, the Sony Xperia Z3 rubber bumper is easy to apply to your device, where it is held securely in place. Should you feel the need to change it, perhaps for another colour from the range, it is just as simple to remove. The bumper also benefits from a crystal clear rear cover to offer all round protection.
