I was toasty at Sugarloaf last weekend. Outside temp -2 with windchill -29. All I had underneath it was a thin turtlefur bakalava. I can ride with my ipod without precariously putting earphones under the ear flaps because the earmuff style ear flaps have a place for ear phones. That being said the only complaint I have is that the earmuffs make it difficult to hear when someone is talking to you, so you might be a little loud.
