The trapper hat is a type of winter hat with ear flaps (earlaps). The ear flaps can be tied up on the crown, or left down and tied under the chin.
When the ear flaps are left down, they protect the ears, chin, and jaw from the elements.
Trapper hats are often made entirely of fur, such as the Russian Ushanka, or they can be made of wool, leather, nylon, etc., and lined in fur for added warmth.
