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