It´s Clear and Simple. For Pinlock or standard Visors
What Fog City does for the motorcyclist is easily explained; clear vision even under the most difficult of weather conditions.
How Fog City does this is much harder to explain but when you can’t see, you can’t ride.
The FogCity® Fog Resistant insert lens adheres to the inside of most motorcycle helmet shields. The patented anti-fog coating reduces the formation of fog under normal temperature-humidity conditions even after repeated cleanings. The treatment is extremely hydrophilic which causes condensation to spread as a clear layer, rather than form droplets, which appear as fog.
Also have photochromatic ones for $59.99, Using light reactive technology they transform from a subtle shade of green to a deeper shade of mid blue within seconds in bright sunlight and return to their original colour when the weather changes.
