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.
