Ridiculously over-engineered? Or the perfect case no matter where you're headed? Griffin thinks it's a little bit of both. Simply put, they made Survivor All-Terrain to be the most protective case possible, that you can carry and use every day. Designed and built to meet or exceed military standard MIL-STD-810G, the Griffin Survivor extreme-duty case is built from the inside out to protect your phone from extreme conditions...dust, sand, rain, shock, vibration and a host of other environmental factors. Survivor All-Terrain is built on a shatter-resistant polycarbonate frame clad in rugged, shock-absorbing silicone. A built-in screen protector seals the touchscreen from the outside environment. Hinged plugs seal the dock connector, headphone port, switches and volume controls when you're not using them.
