What Our Gearhead(R) Experts Are Saying: "The Flight Deck M gives you that fighter-pilot field of view without the bulk of oversized goggles. The Prizm lens really makes terrain features pop in all light conditions, and they vent well enough that fogging is rarely an issue."Inspired by the wide visors of fighter pilots, the Oakley Flight Deck M Prizm Goggles maximize your peripheral vision so you can spot every detail on the mountain. The rimless O Matter frame keeps your view open and makes swapping lenses simple with Ridgelock Technology, while the medium fit ensures compatibility with most helmets. At the heart of the Flight Deck M is Oakley's Prizm lens, which filters strategic wavelengths to enhance contrast and definition across changing conditions. Whether it's a bluebird powder day or flat light in the trees, Prizm optics sharpen your vision so you can ride with confidence. The F3 anti-fog coating keeps condensation in check, and triple-layer foam seals out snow while wicking away sweat for long-lasting comfort.
