The men's Anon MFI® Mesh 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 kids' MFI-compatible Anon goggle. Ultra-lightweight mesh fabric offers the perfect amount of warmth for cool to mild conditions, along with breathable performance to prevent fogging. The magnets in the mask can also be easily removed for machine washing or if you choose to wear the mask with goggles that do not have the MFI magnets.
