What Our Gearhead® Experts Are Saying: "I’ve worn the full-size M4s for years, but the M4S fits smaller faces way better without losing any performance. The toric lenses give great clarity in mixed light, and the Magna-Tech lens swap system is so smooth it makes mid-run changes a non-issue."When we want peak clarity, quick adaptability, and a dialed fit for smaller faces, we reach for the Anon M4S Toric Goggles. Offering the same elite optics and helmet integration as the standard M4, the M4S features a slightly smaller frame without compromising field of view. Perceive lens technology enhances contrast and depth perception in variable light, while Magna-Tech® magnetic lens technology makes switching lenses nearly effortless. The toric lens shape combines the best of spherical and cylindrical curves for distortion-free vision across the entire lens. Integrated MFI creates a seamless connection between mask and goggle, and full-perimeter venting ensures consistent airflow to keep your vision fog-free no matter the weather.
