Wiley X Sierra Features The Wiley X Sierra is built around impact-resistant polycarbonate lenses finished in green mirror delivering ANSI Z87.1+ level protection for range days and outdoor work alike. Polarized lenses with 100% UV protection cut glare and block harmful rays keeping eyes comfortable in bright conditions. Removable side shields add extra coverage from the sides without permanently committing the wearer to a bulkier profile. Built-in lens ventilation helps prevent fogging a detail that matters during fast-paced range sessions or humid outdoor conditions. The frame itself is molded from Triloid Nylon in a Matte Graphite finish sized for a medium to large fit that suits a wide range of face shapes. Dual-injected rubber temple tips and rubber molded nose pads keep the glasses secure and comfortable through extended wear reducing pressure points during all-day use. This combination of lightweight frame construction and ergonomic touches makes the Sierra a practical choice for shooters who spend hours behind the gun. Whether on the range or in the field the Wiley X Sierra delivers protection that does not sacrifice comfort or style.
