raptic shield, compatible with apple iphone 11 (formerly x-doria shield) - military grade drop tested, anodized aluminum, tpu, and polycarbonate protective case, apple iphone 11, red x-doria raptic shield combines hard polycarbonate, soft rubber and anodized aluminum to form the best protective iphone case. the use of machined metal instead of plastic provides military-grade drop protection without the bulk. drop tested to survive 10’ (3m) drops on concrete, raptic shield is the ultimate way to protect but not cover up your iphone. a heavy-duty, machined aluminum bumper protects the perimeter of your device, while inside, soft rubber bubble pattern wraps around your iphone, absorbing and deflecting any shock your device experiences on impact. an oversized raised lip protects your screen from drops and surface scratches. in the rear, clear polycarbonate protects your device without covering it up. an integrated sound channel amplifies the bottom speaker and redirects sound to the front of the case for the best sound experience. simple snap on construction means no tools are required.
