We think it's a little bit of both.

Simply put, the Griffin Survivor All-Terrain Case is 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 All-Terrain Extreme-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 All-Terrain 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, and hinged plugs seal the dock connector, camera lens, headphone port, hold switch and volume controls. A detachable heavy-duty clip secures your iPod touch to a belt or bag strap.

Survivor is independently tested and verified to meet or exceed environmental testing standards for blown rain, blown dust and grit, vibration, shock, temperature and humidity.
