With a bold design made from high-quality materials, the Wiley X Slay delivers a sharp appearance with high performance capabilities. The temple guards and nosepiece are rubberized to keep the glasses in place even during intense activity. The shatterproof lenses naturally block 100% of all UV rays up to 400 nm in wavelength to protect your eyes in extremely bright conditions. These glasses exceed the ANSI Z87.1-2003+ standard for high velocity safety, giving you a pair of eyewear that is built for the long haul. A leash cord, cleaning cloth and large zippered case are all included so you can get to work (or play) right away.
