Bellweather has some good gear. Craft has a lot of xcountry ski jackets. Look for something that has a windproof front and a breathable weave in back. For a ride of a few blocks it's not important but if you commute 10 or 15mi in winter, being able to get your sweat to pass out the back is important. My wife and I will stop occasionally and brush off each other's backside, clearing the frost that forms from our sweat. You may need a windproof layer over that in really cold temps but down to about 0F I much prefer my backside to be very breathable.
