Simply put the most protective case we've ever built. Tested and certified to meet or exceed US Department of Defense Standard 810F and UK Department of Defense Standard 00-35 Griffin's Survivor Military-Duty Case is designed from the inside out to protect your iPod touch 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. Detachable heavy-duty clip secures your iPod touch to a belt or bag strap.
