Yep, I really like a thin one that is like pile inside and windproof on the outside. One of mine feels like neoprene wetsuit on the outside. Both are thin enough to wear under a helmet. They are a favorite clothing of mine item for trouring, backpacking, xc skiing, snowshoeing, MTB-ing, and trail running. REI sells a nice one (Novarra house brand).. It only covers the tops of my ears, but I find that sufficient in any weather not much below 0F for most sports of maybe a bit higher at higher speed on the road, but it has always been fine on tour or for other sports.
