Abbi
Ski Diva Extraordinaire
I found a big improvement in the amount of fogging of my goggles when I got these cloths and did the inside of the goggle. The Abom goggles do not have an inner coating like most goggles, they rely on their heating, so you're always worrying about the battery. I'd use these even on non-Abom goggles, tho, because inevitably those coatings get disturbed. These cloths seem to be more effective than the equivalent Smith ones I've used. This should also help when it's just your glasses. Not a total fog eliminator, but seems to be reduced and dissipate faster.

I got something similar at my eye doctors. It was working for everybody in the office. No joy for me! Makes me crazy because I like to wear glasses except when I am skiing when I wear contacts. One day I will find the right product!
