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.
Compatible with iPod touch 5th and 6th generation.
