My Suomy doesn't fog. My Arai Quantum was terrible though. My biggest problem is keeping my glasses from fogging.....thinking of trying contacts soon.
Yup, my glasses is my biggest concern.
And be careful with contacts. A friend of mine lost his on an unexpected speedbump. Since he didnt have his glasses with him he forced himself to ride home. Crashed his Duc 916 into a ditch trying to avoid the bike in front of him.
I'm thinking about getting those laser eye surgery to make the problem go away permanently
