A monolithic shield of optically pure Plutonite® is flanked by lugs of stainless steel. Patented XYZ Optics® maintains clarity at all angles of vision, even with raked-back lens contours that open your peripheral view. Our proprietary lens material blocks 100% of all UV and allows Dartboard™ to exceed ANSI Z80.3 Industrial Standards for impact protection. Unobtainium® inlays offer a comfortable, secure grip. All Oakley eyewear is warranted for one year from the date of purchase against manufacturer defects.
