The only visor that meets and exceeds the demanding Z87.1 standard for optical clarity, which provided distortion-free optics through the entire range of vision. Every Oakley Visor is coated with AFR, a specially formulated coating that provides anti-fog and scratch resistant properties to the polycarbonate visor, which ensures unsurpassed clarity and durability in any temperature condition. Also acts as a replacement sheild for the full face sheild.
