Anti-fog it is, but...
pro: it helps get rid of the fog con: it rubs against the helmet edge, while opening and closing, hence, it gets out of position and unseals from the visor.

The BEST Anti-Fog System ever
I have tried everything. In Seattle you ride in the rain and cool weather. I have tried Fog City, sprays, breath guards etc. Pinlock works because it uses second shield that is held in place by tension and a silcon seal. Fog City only uses the seal which I found to be good for a month or so
