I know this is an old post, but I've just done a big science project on anti-fog solutions. I've settled on FogTech for the visor, but it seems to smear a bit on my prescription glasses (apparently because of anti-glare and anti-scratch coatings on the lenses).

It was driving me NUTS! I'd get my Gerbings gear plugged in, my jacket and liner zipped, my helmet secured, then I'd put on my glasses and...immediate opaque fog. Argh!

I Googled every anti-fog solution I could find, laid them out on my kitchen counter, and cleaned/coated/tested. I'd stick the glasses in the freezer for a few moments, then take then out into my chilly garage, put on the helmet, shove the glasses over my ears, close the visor, and breathe. Then I'd cuss.

...until I found Clarity DeFogIt (http://www.defogitworks.com/). It seems expensive (~$9 for 5ml!), but a drop will do the job. Shake it first, then spread it over both sides of the lens (I just use a clean finger), gently buff with the included microfiber cloth and ahhhhhh...now I can see!

Turns out they also sell a kit of 3 FofIt-impregnated cloths at WalMart in the Vision Dept for about $4. Seems to work as well as the liquid.

Hope it works as well for everyone else!
