Keep warm with a beautiful hat knitted in Montana. These hats are made of Predator Friendly Wool, which comes from sheep raised by ranchers and farmers who do not kill native predators on their land -- coyotes, mountain lions, bears, and wolves. By choosing certified Predator Friendly Wool products, you are sharing the risks and rewards of sustainable agriculture in America. One size fits all. Hats are hand-made so availability varies.
