Wiley X Sierra Features The Wiley X Sierra pairs a polarized blue mirror polycarbonate lens with a durable Triloid nylon frame to deliver clear glare-reduced vision in bright conditions. The polycarbonate lens construction resists impact far better than standard glass or acetate giving the wearer real protection without added bulk. Removable side shields extend coverage for ANSI Z87.1 plus rated environments where lateral debris is a concern then come off easily for a more casual everyday look. The matte black finish keeps the frame understated while the medium to large sizing accommodates a wide range of face shapes. Dual-injected rubber temple tips grip securely without pinching and rubber molded nose pads distribute weight evenly across the bridge of the nose for comfortable all-day wear. Built-in lens ventilation channels airflow across the lens surface to reduce fogging when moving between temperatures or working up a sweat. The 100 percent UV rating shields eyes from harmful rays during extended outdoor use whether on the range the job site or the trail. These combined features make the Sierra a dependable choice for anyone who needs rugged eye protection that does not sacrifice comfort or style.
