Coldest ride for me since early spring, about 28 F. Broke out the winter gear - full tights, warmer gloves, balacava. Wore my Craft rain jacket because there is a slight chance of light showers this afternoon. I was very comfortable, and managed to stay warm without sweating, which is nice. The colder weather seems to be shortening the charge life on my light batteries, so I am having to recharge more frequently.
