AGF has introduced the Ballistic SG Series Case for the AT&T iPhone 4 offering 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 two, made of a tough impact-resistant polycarbonate. Last but not least, layer number three (the inner-most layer) is made of a soft silicone. This layer also includes our Ballistic Corners™ where all four corners have extra shock absorption where you need it the most. . Phone Compatibility: iPhone 4 (ATT)Other products from A4C
