I accidentally put my nice warm wool socks through the laundry and now they suck... I usually wear a ski jacket, some salomon ski gloves, jeans and hiking boots. This is good until about -10 to -15c. Once it gets past that I'll start layering under the jacket (with wicking bike clothes on at the base layer) and put on a pair of pearl izumi tights/snowpants deal that I picked up before winter. I have been considering getting a cycling specific jacket shell but my ski jackets work too well to really justify it.
