Smith makes a "Turbo" lens that is especially designed for this problem. I think they are basically ski goggles, they have some holes drilled at the top of the lens are are backed with foam on the inside. But that doen't really solve your Scott problem now does it? You could try an old suba diver's trick... spit inside of them, and use your finger to smear your saliva around. lol, sounds dirty I know, but it's cheap and might work :cool:
I had some Smith Top Fuel goggles, and they fogged badly. I used some of those Scott anti-fog cloths on the inside of the lens, and that stopped the fogging problem. The only thing I didn't like was that the inside of your lens takes on this greasy/oily film. Doesn't affect vision much, but on the really hot and sweaty days, oily condensation would build up inside the lens.
This past fall I tried a pair of Pro Grip light-sensitive goggles. Temps were in the 50's to 60's, riding in a combination of fast and slow woods. Classic conditions for chronic fogging on the Smith Top Fuel and traditional goggles. The Pro Grip rep claimed zero fogging, and you know what.... he was right! I have used these on 4, 3-4 hour trail rides, and they never fogged once. Temps ranged from the low 40s through the mid-60's. We'll have to see how they do in the summer next season.
I also tried a pair of Scott Voltage Pro goggles for a day, and they were fog-free as well (same conditions).
I would invest in a good pair of anti-fog goggles, and skip the anti-fog cloth. If you can't see while riding, it really sucks, and taking your goggle off to see is a really bad idea. I know a guy that tore a cornea doing it.
I used to wear my glasses as well and the Smith Turbo goggles with the fan were the only thing that worked for me. That combined with the Fog Clothe. I have contacts now but still use the Fog clothes. These things are great and pretty cheap.
Ive used the scott no-fog wipe. It works o.k. but it causes the condensation to collect in droplets creating a little distortion, but way better than fogged over lenses!!! Another item that I have found VERY helpful is a "nose guard" that mounts on the bottom of my Oakley's. It also direct more air up through the bottom of the goggles so any fog or moisture is more quickly evaporated. Mine is pretty old, but I think I've seen something like it for scott goggles, maybe smith.
the pro-grips are the way to go for sure.i have raced in everything from 20 degrees to 90 degrees,rain all of it and those things never fog up.i can sit on the line for 5 min in the dead of winter and no prooblems.i highly reccommend them.
