I'm in Los Angeles, I am looking forward to the "winter", won't have to take 3 showers in a day from commuting.

In "winter" I wear wool socks(all year round), full finger gloves, cycling shorts with knickers(wind/water resistant) over them. Then usually just a wool t-shirt or one cycling shirts as a base layer, with a synthetic cycling hoodie on top, that usually comes off about 2 miles into my commute. I've acquired another long sleeve wool+synthetic shirt which will probably make the rotation this winter. I find that I really don't need that much as I get pretty warm once I start riding
