Beautiful, crisp morning at around 30f here in DC/MD. With no wind, this is perfect commuting weather for me. I seem to find a good layering combo at around 30: sweatpants on bottom with wool socks; long-sleeve wool-blend jersey with a fleece vest and light reflective windbreaker with vents open. Thin beanie under the helmet to cover the ears; glove liners and light-midweight gloves to complete the ensemble. Little sweat, no frozen bits. I wish it would stay 30 and windless all winter!
