Natural gut is usually offered in coated form, to reduce its tendency to unravel, particularly when humid or wet. Synthetic gut is nylon, nearly always composed of a single filament. It is a very inexpensive string to manufacture and is generally the least expensive string to purchase. Small changes from pure nylon are usually found in strings sold as "synthetic gut".
