The Anon M4 Toric is an incredible pair of goggles with premium optics and an integrated facemask. Anon's new Perceive Lens Technology that filters light to sharpen your visual awareness. Having more visual awareness enhances color and allows you to see better in any light condition on the mountain. The Perceive Lens also contains a low friction hydrophobic coating that reduces smudges, fingerprints and water beading up on the lens. Toric Lenses match the curvature of your eye to eliminate distortion and deliver an ultra-wide field of view. The Magna-Tech Quick Lens Change Technology uses 16 rare earth magnets that allow you to swap lenses out on the fly. The MFI (Magnetic Facemask Integration) also connects to the frame using magnets when the snow picks up and the wind starts to howl. If you want premium optics in a medium to large fit that you can swap out lenses in a flash the Anon M4 Toric is the perfect option for you.
