The Anon MFI® Midweight Neck Warmer snaps magnetically into compatible Anon goggles via MFI® technology, eliminating the gap between face protection and goggle frame. The integrated design prevents cold air infiltration and snow ingestion while maintaining a clean, streamlined look. Compatible with M4, M5, and other MFI-enabled Anon goggles.

• MFI® Goggle-Ready: It comes with all three types of MFI® carriers, so it's compatible with any pair of MFI® goggles.
• Mesh Ventilation Panel: A mesh ventilation panel in the center serves as a vent for your breath, so your goggles don't fog up.
• Removable Magnetic Carrier: The carrier insert is removable for machine washing or to wear the face mask with non-MFI® goggles.
• Lifetime Warranty
