The Anon M3 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. A low-profile cylindrical lens offers a wide field of view, while the terrain defining PERCEIVE lens enhances contrast for a clear read on every feature, no matter the light. Full-perimeter vents plus moisture-wicking face foam provide fog-free clarity to anticipate every turn. They are over the glasses compatible, include a bonus PERCEIVE lens for cloudy conditions, and a microfiber bag for storage and lens cleaning.
