Tucson , Az.. here. I ride everyday to work and back totaling about 41 miles. Typically I wear this time of year jeans and chaps, uppper body layered with t-shirt long sleeve shirt , two sweaters with a thinsulate lined leather jacket over that, a heavy full head belaclava over a doo-rag with a good pair of goggles finishing with a velcro heavy duty half belaclava once again over the lower face and nose and heavy gloves.
I stay toasty that way for the most part. Usually dont need all the layers for the evening ride home.
