Ridiculously over-engineered? Or the perfect case no matter where you're headed? We think it's a little bit of both..Simply put, Survivor is the most protective case we've ever built.Designed and tested to meet or exceed US Department of Defense Standard 810F, Griffin's Survivor Extreme-Duty Case is built from the inside out to protect your iPhone from extreme conditions ... dirt, sand, rain, shock, vibration and 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 and volume controls. A detachable heavy-duty clip secures your iPhone to a belt or bag strap.
