In mildly chilly temps I can get away with just a cotton buff or earwarmers, but when it starts getting windchappingly cold I switch to this Sugoi Balaclava. The fabric is somewhat smooth and silky feeling on the outside, and slightly fleecy on the inside. But it's not made of fleece per se, I find heavier fleece balaclavas to be great for cold weather camping (especially at night) but when I'm working and sweating they're too hot.
