Wiley X began 25 years ago in an effort to provide the US Military with protective eyewear. Recognizing that most people deal with constant threats to the health of their eyes all the time, Wiley X has since expanded to provide sunglasses for anyone in need of premium performance sunwear. All shades, including the Wiley X Slay Sunglasses, come with sleek designs and functional materials. The Wiley X Slay Sunglasses have the following features: WX logo on temples. Polarized lenses (depending on frames), which block intense reflected light and reduce glare. Rubber temple tips for comfort and grip. Open space on temples. Leash strap to connect the temples included. Exceeding the ANSI Z87.1-2003+ High Velocity safety standard. 100% UV protection. Large black zipper case included.
