Wizard-like photochromic lenses are now available for the Performance Line. These adaptive lenses adjust from a clear to dark tint depending on the light intensity in your environment, and boast a wide VLT range at 75%-17% Performance line features include 2mm thick lenses that meet ANSI Z.87 mass impact requirements plus an all-new extended length arm, specifically designed for our standard frame range, with new beveled emblems. The all-new Quick-Latch side-shield system provides lateral protection from debris and unwanted side light meeting ANSI Z87+ standards with side shields installed. Rubberized Hytrel® inserts are strategically placed in the arms and, notably, now the nose bridge for a fit that is not only more comfortable, but grips and stays in place.
