Oakley A Frame Goggle: For the ultimate in fog-free mountain time, the good people at Oakley have engineered a fog-foiling goggle like none other, the Oakley A Frame Goggle. With specialized surge ports to control airflow, these are the most breathable goggles on the mountain. Oakley’s special homebrew F-3 series anti-fog treatment and dual lens design make the A Frame Goggle a three-tiered fog threat. Check100% UV filtering, impact protection that meets all ANSI Z87.1 / ASTM F659 standards, durable urethane that stays flexible, and (to top it off) a triple-layer polar fleece foam that wicks moisture away from your skin—what else could you ask for.
