I have worn this for a single really cold weather ride. it was the second layer in a 4 layer top and it worked well. I am beginning to believe that riding in thirty degree (F) means that one is always going to be something less than comfortable because little is actually windproof, no matter what the manufacturer claims. Still, this is warm and looks great. I have two other Black Bib thermal jerseys and they are comfortable, wash well, and look great. Can't wait for slightly warmer weather in the early spring.
