Nike's Khyber Goggles adapt to all the environments, conditions, and terrain that you could possibly shred across. A push-and-pull bracket lets you quickly change the lens out on chairlifts, and Nike included two cylindrical lenses to get your collection started. Each lens features Transitions adaptive sun technology, which darkens and lightens the lens in response to sunlight and weather conditions. A spherical dual construction with an anti-fog coating ensures a large vision that stays crystal clear in moisture-riddled conditions, and outriggers pair the Khyber Goggles with any helmet. The flexible frame features a triple-layer face foam lining with Therma-Fit to prevent heat loss, and the silicon-coated strap ensures a secure fit.
