With a design inspired by the helmet visors of fighter pilots, the Oakley Flight Deck XM Prizm Goggle delivers a wide-open peripheral and downward line of vision for spotting all of your lines on the mountain. The Prizm lens blocks strategic wavelengths along the color spectrum to maximize the contrast of colors, making every little detail of the terrain in front of you pop. Just like the full-sized Flight Deck, the XM separates itself from the pack with a clean-cut frameless design and offers super fast and easy lens changing through its lens sub-frame attachment. Triple-layer polar fleece foam wicks moisture from your face and delivers all-day comfort, while the dual vents and F3 anti-fog coating ensure your vision stays crystal clear.
