Coat fabric is an important factor in the construction of a coat, as it affects the look and feel of the garment. Loden, tweed, WOOL, serge, and MOHAIR are all fabrics commonly used to make coats. Loden is a heavy, water-resistant fabric made from boiled WOOL, while tweed is a rough, woolen fabric with a distinctive pattern. WOOL is a natural fiber that is soft, warm, and durable, making it a popular choice for coats. Serge is a twill fabric made from WOOL, cotton, or synthetic fibers, and MOHAIR is a strong, glossy fabric made from the hair of Angora goats.
