Wool worn in layers or wool and other types of fabric layered are a good winter combination. Rivendell has wool shirts for layering and others do also. When I had a 26 mile commute(total) I found with wool and a lightweight jacket was a pretty warm combo for the top and tights that have a double type fabric worn under jeans or by themselves seemed pretty good bottom layer. I also use sometimes winter bicycling boots and they are toasty and maybe a little to toasty. I wear a wool hat and sometimes a headband under the wool hat if it is really chilly. Enjoy your winter commutes.
