RaceQuip® Tear-Offs are 2mil thick and designed to be taller than others to work especially well with RaceQuip® Vesta Series helmets. These clear Tear-Offs (sometimes called tear aways) are sized for VESTA model helmets (12 1/4" center to center) so they will not lift in the center. They work well for all types of racing and come 20 to a package.
