The SCOTT screen locking system features 4 locking notches running through the screen, so whatever the impact, you can be sure that the screen won't be thrown off. What's more, the screen is made of a thicker material (1 mm) to further enhance its strength.
To change the screen, simply open the 4 clips (2 at the top and 2 at the bottom) to remove the screen from the mask in a matter of seconds.
