The Women's Anon MFI Lightweight Neckwarmer protects your face and neck from wind, sun, and cold with a revolutionary magnetic connection that seals the face panel to any women's MFI-compatible Anon goggle. Versatile midweight fabric offers the perfect amount of warmth and breathability for any weather condition. The vent panel at the mouth ensures fog-free performance. The magnets in the Women's Anon Lightweight Neckwarmer can also be easily removed for machine washing or if you choose to wear it with goggles that do not have the MFI magnets.
