The Gear4 Bridgetown case is easy to apply, with large sticker pads that hold each half in place. The two pieces of the case come together to fully protect the back of the device when it is open, and provide a reliable grip thanks to the matte texture of the material and the ridges on the back. A protective piece slides in and out of the back part of the case to protect the hinge when the device is closed. This case is made with D3O Bio, sustainable and renewable plant-based materials designed to harden upon impact and dissipate the shock to keep your device protected. Renewable plant-based material Protect your phone and the planet when you choose Gear4 cases with D3O® Bio: containing 52% renewable plant-based materials with no compromise on impact protection.
