yeah could be the very dry cold helps.. seems like the colder it is the less trouble i have too..
skiers can get away with goggles without trouble because they dont generate as much eat using gravity for their momentum.. downhill anyway.. nordic skiers cant get away with it as easily.. especially at race pace.. I dont commute in the winter anymore, but where this could have really been a bennifit is in traffic when you have to stop at a light for instance.. they would fog enough to make it cloudy until you got enough wind going again.. i only use these when its pretty cold.. I have a pair of BugZ Lunaz that I use when the wind chill isnt as dangeous... I have other uses for the fan goggles too.. they are great for shoveling snow and snow blowin.. but heck with cold and snow anyway.. bring in the rain!!!!!... wash away the salt..
