The EZ Tear provides a shield for the folded tear-offs to keep you from grabbing them by accident. It protects the folded tabs and guides your hand to the top tear-off so you can get the full benefit of every single tear-off and ultimately keep your vision clear so you can focus on the racing and not fumbling with tear-offs.
The EZ Tear is universal and attaches between the lens and the tear-off post and adjusts to accommodate the tearoff tabs on all brands of helmets and tear-offs.
