Case-Mate is taking on Otterbox for the claim of best super-protective case. The Otterbox Defender series has long-been the go-to case for those looking to keep their iPhone free from harm -- but Case-Mate says the Tank provides military-grade protection for the iPhone 4 and 4S.
Modeled after motorcycle helmet engineering, Tank is designed with a hard, impact resistant exterior and a shock absorbing interior. A shatter resistant, polycarbonate hard shell combines with the thick, silicone cushioned interior.
The retractable screen shields from impacts, cracking and condensation, fully protecting the iPhone screen. The Tank exterior is made of a premium, soft grip texture that slides easily in and out of your pockets. The Tank tests number one in impact resistance against the leading brand, and meets or exceeds US military standards.
