Try a Polartec Neoshell jacket. Lou at Foxwear dot net can make you one inexpensively. Temp range on mine is 20 to 45 degrees F with great comfort. Check out the video below or icecyclist for more info.

With this jacket you will only need one long sleeve wicking layer underneath. It vents like nothing I have ever used while keeping just enough heat within the jacket to keep you nice and warm. Blocks 99 percent of wind so the windchill is not relevant as a temperature measure for this jacket.
