giro buster goggles namuk northern lights

From corduroy groomers to fast laps in the mini park, kids will be able to count on the Buster's many features. And with so many color and graphic options to choose from, the only hard part might be figuring out which option to go with. 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.
