The Anon Women's WM1 Snow Goggles feature Magna-Tech Quick Lens Change Technology, which uses 14 rare earth magnets to make lens changes easier than ever. Womens-specific design ensures the best possible fit and comfort. Spherical Lens Technology mimics the curvature of the human eye for superior optics, while new SONAR Lenses by ZEISS enhance contrast for the best possible definition and terrain recognition. The super convenient Magnetic Facemask Integration (MFI®) seals your Anon MFI® facemask to the goggle in one quick snap. Additionally, the WM1 goggle is Over The Glass (OTG) compatible for wearing with eyeglasses.
