Lots of different anti fog available. They all work on the same premise - prevent moisture from building by filling in any imperfections on the inside of the visor.
I have had good success with FogZero and CatCrap if you want a commercial product.
If you want a cheaper alternative that works just as well - use Pledge furniture polish. Seriously.
Lots of guys I referee and play hockey with use it for the same reason (inc. me).
I never knew Pledge will prevent fogging

For helmets i owned, Scorpion anti-fog shield is best Shoei is useless w/out the pinlock.
