The use of machined metal instead of plastic provides military-grade drop protection without the bulk. Drop tested to survive 12’ (4M) drops on concrete, Defense Ultra is the ultimate way to protect but not cover up, your phone. Every Defense Ultra case from X-Doria starts from a solid block of metal, machined to the finest detail to create the ultimate device protection. The Defense Ultra contains four layers of protection for your phone; DropShield elastomer, hard polycarbonate, TPU and anodized aluminium. Meticulously combined, these materials allow this case to fit your phone with ultra-precision without the bulk.
