rain, fog, helmets

[Arden Kysely]

Has anyone tried either of the products here http://www.fogtech.com/ ? If they work as shown, they could make winter riding a lot simpler and safer. I have a Scorpion helmet with a fog-free visor that works OK, but seems to be losing it's magic, and I'm always looking for something to keep the rain drops from sticking. __Arden
