What Our Gearhead(R) Experts Are Saying:"I run the M4 with the MFI mask on the coldest days of the season and the magnetic connection actually stays sealed, no gap letting wind in around my nose. The Magna-Tech lens swap is so fast I can go from a bright bluebird lens to a flat light lens without ever taking off my gloves."We step off the lift into wind that's been picking up all morning, and this is where the Anon M4 Cylindrical Goggles and MFI Face Mask combo earn their place in the kit. Built for riders who face everything from bright bluebird mornings to biting, exposed ridgelines, this setup adapts to the mountain instead of asking you to tough it out. The Magna-Tech lens system uses powerful magnets to make lens swaps nearly effortless, so dialing in the right tint for changing light takes seconds instead of minutes fumbling with frames. The MFI face mask clicks onto the goggle magnetically for a gapless seal against cold air, and full perimeter venting keeps things fog free even with the mask attached. A bonus cylindrical lens, storage case, and lens protector round out a kit built for riders who want to be ready for whatever the day brings.
