The Anon M2 Snapback Goggles feature MAGNA-TECH® quick lens-change technology, using powerful magnets to make lens changes easier than ever. A snapback strap eliminates pressure points for comfortable wear under a helmet. Their spherical lens mimics the curvature of the human eye for precise optics, while the polarized lens reduces glare for crisp, clear visuals in bright conditions. They include a bonus lens for cloudy days and a microfiber bag for storage and lens cleaning.
