Ballistic created the Ballistic SG Case for Samsung Epic 4G Touch, with not one...not two, but THREE layers of protection. The first and outermost layer is made of soft TPU which will help absorb the shock of a drop. In addition, this first layer, is co-molded onto layer number 2, which is made of a tough impact resistant polycarbonate. Last but not least, layer number three, which is the inner-most layer, made of a soft silicone. This layer also includes Ballistic CornersTM which means all four corners have extra shock absorption where you need it the most!
