Defense Shield combines hard polycarbonate, soft rubber and anodized aluminum to form the best protective iPhone 8 and iPhone 7 case. The use of machined metal instead of plastic provides military-grade drop protection without the bulk . Drop tested to survive 9.9' (3M) drops on concrete, Defense Shield is the ultimate way to protect but not cover up, your iPhone 8 or iPhone 7. A heavy-duty, machined aluminum bumper protects the perimeter of your device, while inside, soft rubber wraps around your iPhone 8 or iPhone 7, protecting from drops and ensuring metal never touches your device. 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.
