Winter coat lining can be made from a variety of materials, including FLEECE and FUR. FLEECE is a soft, lightweight fabric that is often used for insulation and warmth. It is usually made from synthetic fibers such as polyester or acrylic. FUR is a natural material that is often used to line winter coats. It is usually made from animal skins, such as mink, fox, or rabbit. Both materials are popular choices for winter coat lining due to their insulating properties and ability to keep the wearer warm.
