The last two times I have commuted 15 miles with temps in the low 20's, I used my balaclava but had to remove my eye wear (clear safety glasses) because they were fogging up so bad. I only have the issue when I have the balaclava covering both my nose and mouth. If I pull it down to expose my nose and mouth I don't have the problem, but then my face gets too cold.
What sorts of eye wear are less prone to fogging? I heard mentioned "Visorgogs" in the commuting forum. Anyone used those or have another good option?
