Is there such a thing?
A buddy of mine picked one up from nothern power and had no problems with fogging. I bought the same helmet and fog city, though much better then my old helmet.
Tought about trying the mask in the helmet to help direct hot air away and down from the shield. This is getting frustrating and exspensive.
I dont like the idea of using the motor cross style though I'm giving that some thought. There has to be something on the market though in a full helmet that works.....
