Slimline is a one of a kind protection for your iPhone. It is simply the slimmest protection out there as it does not cover any main components of the phone. You get the full experience of the phone and feels like there is nothing on it. All bumpers and cases on the other end cover the mid section of the phone, and cases cover the back too, which adds to the phone's size and weight. Our goal was to design the slimmest protection out there by covering the phone as little as possible.
