The Giro Axis Snow Goggles frameless design features an elegant new quick change lens system and clean, bold style. Four self-locating magnets assist in lightning-fast lens replacement and four snap pins (think of a sophisticated version of a snapback cap) keep the lens securely locked in place. The medium fit accommodates a wide range of face shapes while boasting an impressively wide EXV field of view. The Axis includes two of the best lenses in the business with premium VIVID lenses with Optics by ZEISS (one sun/all conditions lens and one Infrared storm/low light lens). VIVID is a patented lens technology - developed by Giro in partnership with Zeiss Optics - that improves the visual experience on snow by enhancing contrast and definition. VIVID reduces eyestrain, improves reaction time, boosts confidence and delivers precise vision without color over saturation. The VIVID Onyx lens features a silver mirror treatment that enhances contrast while limiting color peaks, providing less eye fatigue and improved reaction time in bright sun.
