The Anon MFI® Hellbrook Balaclava 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.
