I do wear tights...a couple have doubled up knee areas and are invaluable on the cold cloudy days or cold damp days. If cloudy and under 50 or breezy and under 50, the tights come out. Above that is simply weather for knickers because I can go from a sunny 45-65 with knickers and warm socks. It is often sunny here, even in the winter, so it stays pretty warm since the sun is so intense at altitude. I even loved Assos' lycra-only (no fleecy material inside) and my biggest disappointment is that they were discontinued.
