Our Presidio METALLIC cases have a polycarbonate shell molded together with shock-absorbing IMPACTIUM rubber for two layers of protection in a one-piece case. Ridges of IMPACTIUM rubber on the inside perimeter of this Presidio case compress on impact to absorb and disperse shock. This case is tested to protect your phone against damage from drops up to 10 feet. All Speck cases are independently lab tested for multiple real-life situations to ensure your device is always protected. We test to protect against extreme drops, extreme temperatures, chemicals, antenna interference, cracks and abrasions, device bending, and more.
