From pro-sized parks to heli-accessed lines, the Oakley Airbrake XL Prizm Goggle delivers uncompromising vision with its oversized design and color-boosting Prizm lens. SwitchLock technology promotes convenient lens swapping when stormy conditions barrel down on your local mountain. Taking advantage of SwitchLock, the Airbrake XL comes with a second Prizm lens for quickly adjusting to variable alpine conditions. Prizm works by emphasizing colors where the eye is most sensitive to detail, allowing you to visualize nuances in terrain and features lurking just beneath the snow, even in glaring-bright conditions. Adding to Prizm's exceptional clarity, the F3 anti-fog coating prevents condensation from obscuring vision during socked-in storms and soggy spring days.
