I am a great fan of the Gore Phantom jacket, which has the added advantage that you can zip the sleeves off if it warms up unexpectedly and ride with a short-sleeved jacket. And it's day-glo yellow as a bonus.
But having said that, I don't ride in the real winter. As soon as the temperatures drop to freezing (like round about now), I wimp out.
