The unique thing about cycling that is often ignored is that the wind is always from the front, so you can put wind-blocking fabric on the front only and the back can disperse vapor. This prevents the steam-bath effect.

I would highly recommend the Kucharik wind-front wool jacket. I wear it all winter here in knoxville. With appropriate layers, it is good from about 50F down to under 20F. Not too geeky for full-time casual wear, and also works fine on long winter rides in bike duds.
