The Footprints Goggle is a re-imagination of the first snow goggles ever to be produced. Retro design meets technical features from the present. There's no school like the old school. FEATURES: Spare lens included Cylindrical lens shape Medium / Large fit Helmet Compatible and Over the Glass Compatible (OTG) GOGGLE CARE TIPFog happens—it's just part of riding in the mountains. To keep your goggles in top shape, never touch the inside of the lens; there's a super delicate anti-fog coating that can be damaged with even the lightest touch. Always store them in a soft bag, avoid placing them face-down, and let them air dry naturally after use. Steer clear of heaters or humid spots to keep them clear for your next run.
