The Griffin Survivor for Kindle Fire HD 7" is designed to provide heavy-duty protection for your e-reader device. The case is durable and rugged enough to meet US Department of Defense standards regarding the environmental resilience of equipment so it can provide thorough protection for your Kindle in most any situation. An integral display shield protects your e-reader's screen from weather elements such as wind and rain. A rigid internal frame cushions your device against bumps, shocks and drops so it can remain intact if it falls off a table, and be protected during bumpy rides while traveling. Seals for your Kindle's ports help keep out dust and other debris so connections remain strong and consistent. Silicone cladding built into the Griffin Kindle Fire Case prevents your device from experiencing the negative effects of vibration.
