fits well with helmet and keep my head and ears warm in winter, perfect!
Riding in 25-35 degrees F this winter with my old system (a headband + an ill-fitting wool cap) wasn't awesome. This hat is a gamechanger for me! It's very fitted (note: I wear a Small helmet and it's tight--in a good way) and the brim is a bit smaller than most cycling caps, which I like. It's warm, looks good, and a great value for the price.
