Dual-Vented Lenses with F2 Anti-Fog Coating - Goggles with dual vented Lexan lenses take advantage of Oakley F2, an anti-fog coating developed specifically for cylindrical lens geometry. In addition, all Oakley snow goggles undergo rigorous testing to ensure venting is evenly balanced for added protection against fog buildup.
Combine that with full 360° frame venting and you're ensured optimum airflow to help eliminate fog buildup.
