ESR Case for iPhone 6/6s, Three Layer Heavy Duty Shockproof Protective Case [Free Screen Protector] [Metal Design] [Matte Silicone Back + Thickened TPU Bumper] for iPhone 6/6s 4.7"-Grey Patented Tri-layer design: The outer case is Anti-scratch Hard PC Back. The soft TPU bumper inside has an embedded solid X-Bone frame that attenuates shocks evenly and strengthens the structure of the case. Also the two steel mesh groves provide extra ventilation for the iPhone. The Shielder's Special: The TPU Bumper was thickened to 4.7 mm at corners to protect the iPhone from accidental drops. Better corner protection of the ESR cushion design provides better shock absorbency. Better Screen and Camera protection: The case has a 1.2 mm raised bezel offering increased protection to the surface of the screen. There is also a 2.5 mm raised bezel to protect the camera. Excellent Grip: Being textured along the sides of the case it provides a better grip against slips of everyday use. Larger Ports: The port openings were enlarged for larger headphone jacks like Beats.
