The Anon M3 Goggles feature MAGNA-TECH quick lens change technology, using powerful magnets to make lens changes easier than ever. A low-profile cylindrical lens offers a wide field of view, while terrain-defining PERCEIVE optics enhance 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 MFI compatible for seamless face mask coverage and over the glasses compatible for wear with eyeglasses. They include a bonus PERCEIVE lens for cloudy conditions plus a microfiber bag for storage and lens cleaning.
