Wool and wool blends good. Crosscountry ski pants over bike shorts and merino- poly longjohns great for legs since rain and snow bead up on the outside. Balaclavas good, too. I wear $3 wool liner gloves under 240 gram thinsulate gloves or mittens. I also like windblock fleece over a couple layers since i found one in red. HiVis good in sketchy vision situations..
