The Anon M4S goggles (Cylindrical) + Bonus Lens + MFI® Face Mask offer the M4's widest field of view via cylindrical lens design, with the added versatility to swap between cylindrical and toric lenses using Magna-Tech® magnets. MFI® face mask integration creates a seamless, gaper-free interface with Anon helmets, while the low-bridge fit frame is engineered for smaller face profiles.
