The men’s Anon Circuit goggle features Magnetic Facemask Integration (MFI®) that seals your Anon MFI® facemask to the goggle in one quick snap. Toric Lens Technology mimics the curvature of the human eye for superior optics while also providing enhanced peripheral vision and maximizing the possible vent volume in the goggle. NEW SONAR Lenses by ZEISS enhance contrast for the best possible definition and terrain recognition. Anon’s Lightweight Thermoplastic Polyurethane (TPU) Frame has the highest resistance to abrasion, maintains consistent flexibility in changing temperatures and has superior elasticity to fit every face shape. Full Perimeter Channel Venting works in tandem with Integral Clarity Technology to provide clear, fog-free vision in all conditions. The Circuit goggle is Over The Glass (OTG) compatible for wearing with eyeglasses. Includes microfiber goggle bag for storage.
