Start with a cozy hug of silicone all around. Those flashes of color peak around edges and protect every corner. Add a strong plastic shell on top of that to absorb each hard knock. With the Tough case, your HTC One S is secure in motion throughout your active day. Not only does the Tough case mean business. It means business in lightweight, practical style. Its slim profile has your new tool completely covered - without adding bulk. The case uses two of the most durable materials on the market - hard ABS plastic and silicone - to protect the hottest technology.
