The Oakley A Frame Goggles has a three-tiered defense against fog with surge ports to control airflow, F-3 Series anti-fog treatment, and a dual lens design with a thermal barrier of trapped air. Oakley took all that technology and juiced it with the precision of High Definition Optics® (HDO®), topping it off with a wish list from the pros: 100% UV filtering, impact protection that meets ANSI Z87.1 / ASTM F659 standards, durable urethane that stays flexible, and comfortable triple-layer polar fleece foam with moisture wicking. About the only thing you don’t get with the A Frame® goggles is fog.
The Dark Grey (17% VLT) Lens is a contrast option for Sunny Conditions and a protection index of 3.
