A hard top layer spreads the impact over a wider surface area whilst a second layer, BulletshieldTM featuring BASF polymer found in bullet proof glass, absorbs and dissipates impact. A final third soft layer dampens force and further absorbs impact protecting your screen with the most intelligent impact protection yet. An advanced self-healing anti-scratch layer created with reflowing polymer completes the world"s most advanced HTC One M8 screen protector.
