The men's Anon MFI® Lightweight Neck Warmer protects your face and neck from wind, sun, and cold with a revolutionary magnetic connection that seals the face panel to any men's and kid's MFI-compatible Anon goggle. Lightweight fabric offers the perfect amount of warmth and breathability for cool to mild conditions. The vent panel at the mouth ensures fog-free performance. The magnets in this Anon 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.
