The term fur generally refers to the thick coat of soft hair that covers the skin of some animals, which is used in the making of garments as trimming decoration or as lining in footwear. Most recently, out of concern and protection towards animals, faux fur has been developed from synthetic fibers to resemble very closely natural fur and still maintains the same properties of softness and warmth.
