If you are using a bumper case, we would suggest you purchase one as not all impacts happen on the screen or the sides.
Although the bumper case provides plenty of protection for daily usage as the bezel on the back can protect your phone from a direct impact on a flat surface. It only acts as a 1-line defense against drops & knocks, which is why we always suggest users pair it with a front & back screen protector for optimal protection!
We know that many of our customers prefer to use our bumper without anything on the back so they can feel the back of the phone. For those who would like a bit of texture and protection, why not pick up one of our Impact Skins instead?
