The Polar Bear musher hat is warm, snug, and fits comfortably. It covers the forehead and back of the neck well. Bendable metal wire in the brim. Outer layer made of soft-shell with membrane. Lined with soft, 100% merino wool, which does not itch. Wool absorbs moisture and keeps you warm even it it’s wet. Therefore, lining made of wool is better than fleece (made of plastic) in a hat like this. Developed in collaboration with mushers.
