Desc. Features Specs & Guarantee Introducing a complete evolution in product - We’ve taken our legacy Vise frame and given it a complete overhaul, making them Z87+ out of the box, featuring new performance arms, with an integrated Quick-Latch side-shield system. In the comfort department you will find rubberized touch points throughout the frame also ensuring that the frames stay in place on your face. The cherry on top of the performance line is a lens matched side shield melds form and function together for a look that is flat out stunning and is entirely unique to the performance line. Performance line features include 2 mm 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.
