we don't get very cold winters here, but i have a set of JL velo arm and leg warmers (under stuff they work well too) and some swrve winter weight knickers that are amazing as long as it's not terribly wet out. anything that breathes and wicks sweat... wool, certain synthetics... and layering will make a good kit as long as you dress for the weather. if it's -5 out and you put on a wool base layer and one jacket, you're probably going to have problems. just anticipate your situation and dress accordingly.
