Anon M5 Goggles With Mfi Face Mask

The Goggle

The Anon M5 is a big goggle — not clunky, but genuinely wide with an impressive field of view. If you've been squinting through a cramped frame on a flat Pennsylvania day at Seven Springs, you'll notice the difference immediately. The magnetic face mask snaps on without fumbling with cold fingers, making this feel less like a goggle and more like a full cold-weather system.

What Sets It Apart

The MFI — Magnetic Face Mask Integration — is the real story. Most goggle-and-mask setups either gap out (cold air straight to the face on Roundtop's groomer runs) or bunch up and fog you out. Anon's magnetic attachment pulls the mask flush against the frame. It's not a gimmick — customers have come back specifically to buy a second MFI mask after one season.

It also comes with a bonus lens. Swapping is fast: Magna-Tech uses magnets along the top of the frame, so it's pull-and-snap rather than stretch-and-curse. Worth knowing: the M5 runs large and fits best on medium-to-large faces. Riders with narrower faces sometimes find it sits proud of the nose, letting cold air sneak in. Come try it before you commit — we'd rather tell you now.

Lens Tech

Perceive is Anon's proprietary lens tech, and it delivers. The contrast enhancement makes shadows and rollers pop — on a flat-light day at Hidden Valley when everything looks the same shade of white, that can save you from catching an edge on a rut you never saw.

The flat toric lens cuts glare and distortion across the full frame width, so peripheral vision stays clean. Full-perimeter venting keeps airflow moving — fog complaints are rare with this one, even on high-exertion tree laps.

Fit & Compatibility

The M5 is helmet-compatible with Anon's own helmets and most other brands with a standard goggle channel. Triple-layer face foam seals well without squeezing after two hours. The silicone-lined strap grips a helmet reliably.

Lens options cover a solid range: nOnyx and SunOnyx for mixed light, VarBlue photochromic for changing conditions, and Sun Red for bright bluebird days. Not sure where to start? SunDays variants are strong all-around picks for Mid-Atlantic conditions.
