The Defender case features three layers of defense including a durable inner polycarbonate layer outer silicone layer and built-in screen protector. The two-piece inner layer is built from high quality polycarbonate that snaps around the device to create a secure protective layer. A screen guard is built into the inner layer to protect against scuffs and scratches. The outer silicone layer wraps around the inner layer to create a unified defense against oopsies like bumps and drops.
