Dress to be cool/cold for the first 20 minutes. Wool base layers if cold. At 50 F, I am wearing bibs a jersey, knee and arm warmers and even the ar warmers are questionable. Around 35, I wear leg warmers, my regular bibs, longsleeve jersey and an isulated vest. Below that, flocked tights, wool base layer, wool jersey, light jacket or vest, shoe covers and a balaclava.
