The Wiley X XL-1 Advanced is built to protect your eyes from a wide range of hazards. Using Wiley X's patented Facial Cavity Seal, these glasses block out wind, debris and peripheral light to deliver uncompromised visual clarity. The lenses block 100% of the sun's harmful UV rays. They also use a T-Shell anti-scratch hard coat and Foil anti-fog coating for resilience and visual clarity. These glasses meet and exceed numerous safety standards, including ANSI Z87.1-2003 standards for optical and high velocity impact safety and strict military ballistic standards, making them excellent protective eyewear for use at the range and in tactical operations. The heat-resistant frame wraps around the head to eliminate tunnel vision and features double-injected temples for a secure fit.
