• Mesh Panel A mesh panel in the center serves as a vent for your breath, so your goggles don't fog up.
• Removable Magnets Magnets are removable for machine washing or to wear the face mask with non-MFI® goggles.

Made for mild to cool conditions, the Anon MFI® Lightweight Neck Warmer protects your face from wind, sun, and cold. The adjustable design can be worn as neck warmer in mild conditions and pulls up for full face coverage with a seamless connection to MFI-compatible goggles in colder, stormier weather.
