Winter coats typically feature a LINING, LINER, and liig. The LINING is the innermost layer of the coat, usually made of a soft material such as cotton or polyester. The LINER is the second layer of the coat, usually made of a thicker material such as wool or down. The liig is the outermost layer of the coat, usually made of a waterproof material such as nylon or Gore-Tex. Together, these three features provide warmth and protection from the elements during the winter months.
