'70s-inspired aviator sunglasses designed specifically for those who love motorcycling, with Z87 safety lenses, extra-durable OBE hinges and anti-reflective coating for optimal vision. The yellow NightRider lenses with a VLT of 76% improve your vision during evening rides and low-light rides. The purple AR coating is extremely beneficial as it eliminates reflections from the inner lens, an important feature when riding a motorcycle at night.
