One of my favorite solutions is in this thread: http://www.bikeforums.net/winter-cyc...free-last.html
I seem to recall seeing that some companies are now selling pre-made devices of this kind

On the first test runs, on the coldest days, I experienced a slight fogging of my glasses inside my goggles but the dishwashing soap trick has taken care of that. It is such a relief to not have to worry about losing visibility during my commute.
I have posted more details
here if anyone is interested.
I had corresponded with

I have often posted that for any evaluation of winter gear, the poster should specify temperature
and distance (as a function of time).

One post once suggested that a "cold" ride is one where the water bottle freezes solid; a function of temperature and time. For my 14 miles that occurs at about 15ºF or less (-9.4ºC).
