I'm still happy with my Smiths. Like Pinerider when I stop I tend to fog the lens, and it clears when I get under way. Although the other night with the -4 F temps there was some freezing, and it was difficult to remove the crust.
I've tried the shop goggles, as well as the ones they sell for raquet ball, but the lens' get scratched too easily, making them dangerous on the ride, when on coming traffic hits them with headlights. And ski goggles, well we've all tried them. Like everyone else I don't know the trick to keeping them clear. They work okay, but slowly fog, until frustrated you pull them off, and put on your glasses. I have thought of making larger holes. But one of the problmes with the goggles I've got was the foam that is in contact with the face collects sweat, so that is like more vapor being added to the inside of the goggles. Anyone ever try scuba gear?
