A fur hat is hard to beat when the temperature dips. The best is Otter and mink for durability followed by beaver and muskrat. Long haired animals like fox, racoon, coyote, fisher make good hats but they will never last as long as the first ones mentioned and they tend to go off color the more sunlight they are exposed to. The trapper style that has side flaps that can be tied down over the ears or up as the weather warms are a terrific looking hat. One thing you may want to think about is a hand muffler with the fur on the inside they are very warm.
