We've refined the one that started it all for Heat Wave - Introducing the Lazer SLIM. Everything you've grown to love about the Lazer, just trimmed down for a look that's stylish and clean. The Lazer SLIM comes on our NEW Performance platform and is Z87+ out of the box with our Quick-Latch side shield system, and rubber no-slip inserts in the arms and nose. The SLIM is the proverbial Goldilocks of Lazer Face universe. They feature the width of the standard version, but with 5mm less lens height and a repositioned nose piece, bringing the SLIM to sit further down on the face. The changes are subtle, but the look and fit is drastically improved if you ever thought the original Lazer was just too loud. The Lazer Slim fits great on wide range of head sizes, from male to female and small to large making them the perfect unisex Lazer Face. The performance line is a complete evolution in product - We've taken the unmistakable Lazer Face® frame and given it a complete overhaul, 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 nose for a fit that is not only more comfortable, but grips and stays in place. The lens is a 6C base single lens, that is curved on both the horizontal and vertical axis for optimal clarity and features Heat Wave Anti Fog Tech with a dual surface lens coating that prevents condensation from forming, ensuring your vision stays crystalline and your glasses stay on. *Anti-fog coating is applied to lens only Lens Technology: 2mm thick Polycarbonate lens meets or exceeds mass impact requirements for Z87 standards, injection molded to the highest standards and tested to ensure optimal clarity, along with color and light transmission standards. Heat Wave ANTI-FOG glasses feature anti-fog treatments on both sides and are 100% guaranteed to remain fog free.
