Anon takes its already revolutionary magnet-based lens-swapping technology to the next level with the M2 Goggle. Now frameless for maximum field of vision and a cutting-edge look, this design makes changing lenses insanely easy and fast.Magna-Tech quick lens change technology got an upgrade on the M2. Anon removed the outer frame and buttons so all you have to do to take off the lens is literally grip it and rip it. The magnets are strong enough to survive a tomahawk through powder without coming off so you don't have to worry about losing your lens when you take a tumble. The large spherical lens tapers from the optical center toward the periphery for a wide field of vision with minimal distortion. Full perimeter channel venting allows maximum airflow to keep your lens fog-free, and triple-layer face foam provides a comfy fit that seals out the elements.
