Product notes from OAKLEY:
Lens fog is a performance killer, so we developed a three-tiered defense. First, we devised surge ports to control airflow. Second, we formulated F-3 Series anti-fog treatment. Third, we engineered a dual lens design to reduce fog with a thermal barrier of trapped air. Then we 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.
- Anti Fog Treated Ballistic Lens - Plutonite lens pass ANSI standard Z87.1 for optical clarity, high mass and high velocity impact - Patented Polaric Ellipsoid lens geometry - 100% protection against UV A, B and harmful blue light - Triple polar-tech fleece face foam for maximum moisture wicking - Optically corrected dual lens goggle - Superior venting to eliminate fogging
