Spandex is a synthetic fabric with a polymer base, like nylon or polyester; spandex, however, has unique properties that make it well suited to certain applications, such as sports apparel. The fabric is able to expand up to 600% and spring back without losing its integrity, although over time, the fibers may become exhausted. Unlike many other synthetic fabrics, spandex is a polyurethane, and it is this fact that is responsible for the fabric's peculiarly elastic qualities.
