Yesterday I bought a like new Concept (C1?) from an older gentleman that developed arthritis and had to quit riding before he even got to use it.

Coming to work this morning was my first time to wear it, and it fogged up to almost a scary level. Temp was 25 when I left the house.

Now I'm not new to riding by any stretch and I've never had a helmet fog up this bad. I did all the tricks to de-fog and nothing worked. I really like this helmet but I have to find a cure to this fogging.

By the way, the helmet that it is replacing in an Arai RX7-7, basically a racing helmet. If it even came close to fogging a simple 1/8" lift of the shield cured it right away. This didn't work on the Schuberth.
