These are "Ski Doo" helmets, correct? Versions 1, 2, 3. I see a couple by Can-AM also but appear to be motorcycle. I'm going to look into one myself. I've had glasses forever and CONSTANTLY fog up. I can get by for awhile by leaving my visor cracked open, but then they eventually frost over. It really affects the enjoyment factor because I either cannot see or my face is frozen...
