Griffin's Survivor extreme-duty case is designed from the inside out to protect your iPad from extreme conditions: dirt, s&, rain, shock, vibration, & a host of other environmental factors. Survivor is built on a shatter-resistant polycarbonate frame clad in rugged, shock absorbing silicone. A built-in screen protector seals your multi-touch display from the outside environment, while hinged plugs seal the dock connector, headphone port, hold switch, camera, & volume controls. Survivor is independently tested to meet or exceed environmental testing standards for blown rain, blown dust & grit, vibration, shock, temperature & humidity.
