Check out this sleek, low-profile frame that fits flawlessly with the included face mask (MFI®) for full protection. These goggles feature a SONAR lens that boosts contrast so you can see better without straining your eyes. The spherical shape offers a less distorted view compared to a flat lens and it's never been easier to swap lenses out when the conditions change; Anon's Magna-Tech® quick lens change technology is safe, secure and seriously easy. The lenses offered here are ideal for partly-cloudy to snowy conditions, but really your options are unlimited since you can get every color lens for your gear-bag.
