Looking at it from the back of the phone, the center panel is a hard plastic while the top/bottom/rim is a more flexible plastic/rubber like material

It has high ridges on the face side to protect the screen in a typical drop, the backside allows for easy access to the finger print scanner, the top and bottom parts of the case are made of a sturdy and slightly softer rubber like material which covers not only the top of your phone, but it extends around the corners as well.
