The Marker Posse Magnet+ Red Plasma Mirror adult winter sports goggles offer a high-quality cylindrical lens with NMT Optics coating. NMT OPTICS (Nictitating Membrane Technology) technology is a surface that supplies great visibility. This membrane prevents water, grease or dust from sticking, and moisture wicks away quickly. Fingerprints, dust and sweat have no surface to cling to and thus are easy to remove. The lens of those alpine ski and snowboard goggles is magnetically fixed within the Superfit invisible frame, so it can quickly be swapped if the light gets bad, so you may be perfectly equipped in any kind of light conditions. In addition, a lightweight neoprene box and a microfibre bag are included.
