Laza X Armor Dual Layer Protective Case Don't just cover up your phone, give it a coat of armor. Protection and style in one sleek case. X Armor has it all. The X Armor is the new leader in protective cases providing better impact absorption than any other bulky case on the market. Air Cushion Technology corners reduce the thickness of the case while providing optimal protection for your device. The Tough Armor also features distinct beveled edges and lay-on-the-table design, which reduces bulk while providing better overall protection. Box cases are bulky and heavy making the device inconvenient to use. The other colors are all matte-coated for a fingerprint resistant exterior. The heart rate sensor and fingerprint unlock is fully compatible with this case.
