I left the slopes early yesterday, because a sudden wet snow flurry reduced my visibility to near zero. I was unable to keep my goggles de-fogged.

This isn't the first time that's happened. Over the years, I've tried various forms of stuff applied to the goggles, to no avail.

I know there's nothing that can stop snow from sticking to the outside of the goggles, but is there a such thing as a high tech pair of goggles that is fog-proof on the inside?
