Ridges of IMPACTIUM™ material on the inside perimeter compress on impact to absorb and disperse shock. Dropped from 10 feet multiple times by independent labs to ensure superior protection. A polycarbonate outer shell and an inner IMPACTIUM™ lining are molded together to give you two layers of protection in a slim, one-piece case. Gives phone screen extra protection from scratching and shattering if your phone falls and lands face-down. Angled raised rubber ridges on the back provide a secure no-slip grip and help prevent phone from sliding off surfaces. Designed to allow for Qi wireless charging. Speck® cases are independently lab-tested for multiple real-life situations, including extreme drops and temperatures, chemicals, antenna interference, cracks and abrasions, device bending, and more.
