T-Mobile D30 HTC ONE s 4g (ONLY from T-Mobile) Flex Protective Cover Case Skin Shell D3O Ultimate impact Protection for TMobile HTC one S D-30 Tech 21 Teal with White Stripes

Protect and personalize your HTC One S with the D3O Flex Protective Cover. D3O Flex Protective Cover is made with D3O impact protection technology.

What is D3O technology? D3O is the secret ingredient that's composed of a super high-tech polymer that provides protection in case of impact. In everyday use, the molecules that make up the Flex Protective Cover flow freely making it soft and gel-like. But upon shock or impact they lock together - absorbing the impact and spreading the shock evenly across the surface of the material. That means your phone stays in one piece, no matter how hard the impact!
