Injection-Molded Cylindrical VIVID lenses with Optics by ZEISS® to insure premium lens quality, the injection molding of the Giro Ella Women's Goggle lens minimizes the distortion that can occur in conventional thermoformed cylindrical lenses. VIVID lenses are designed to eliminate flat light and haze for high-contrast vision; the landscape literally pops into focus when you put a pair of these on, you can see contour in the snow so you can confidently pick your line. The Quick-Change Magnetic-assisted Lens System is powered by four self-locating magnets to make lens replacement lightning-fast, with four snap pins to keep the lens securely locked in place. Shipped with two lenses, one for sun/all-conditions lens and one Infrared storm/low-light, you’ll always have the right lens for the day you’re facing. EXV Expansion View Technology gives you a wider and deeper field of vision than you’ve experienced with other goggles, while the EXV frameless design gives these a clean, sleek, styling. Designed to mesh perfectly with your helmet the EVAK Vent Technology works with the front vents in your helmet to keep moist air moving from behind the lens for a fog free experience up there on the mountain. Sized right for smaller faces if you’re wearing a small or medium helmet, look at the Ella.
