The Sync is the entry point into Anon's magnetic lens-change ecosystem, powered by M-Fusion. Magnetic alignment guides the lens into position, and a magnetic latch holds it there, making changes fast and intuitive. Perceive optics deliver the same high-contrast terrain-defining clarity as the rest of the Anon lineup. MFI (R) magnetic face mask integration keeps the face mask sealed to the goggle. Bonus Perceive lens and microfiber goggle bag included. The Sync is for riders who want Anon's optical and face mask integration technology in a capable, no-nonsense system.
