The Sagen Goggle brings top-tier performance to all riders and their unique styles. Park laps, or exploring every acre of the resort, the Sagen keeps you focused on the ride ahead through offering outstanding performance in a beautifully minimal design. Product Features EXPANSION VIEW (EXV) TECHNOLOGY - Perfected at Giro's test lab in Scotts Valley, California, this groundbreaking new frame design serves up unparalleled peripheral vision. We started with a helmet-compatible goggle, and then shaved down the frame rim and added frameless zones to optimize a massive spherical lens focused on the best possible peripheral vision in a goggle. INJECTION-MOLDED CYLINDRICAL LENSES - Injection-molding a cylindrical lens helps refine optics and minimize distortion that can occur in thermo-formed cylindrical lenses. OTG FRIENDLY - Engineered specifically for bespectacled skiers and snowboarders, goggles that are OTG (Over-The-Glasses) feature a finely crafted interior with extra volume to accommodate prescription frames comfortably. Increased air volume inside the goggle keeps your vision crisp, clear, and fog-free. TRIPLE-LAYER FACE FOAM - Triple Layer face foam with microfleece facing SEAMLESS COMPATIBILITY - For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring a seamless interface between helmet and goggle for an exceptional fit and dependable, worry-free function.
