Elastanes are synthetic materials which have similar properties to elastic rubber. They show elastic recovery from very high extensions. The fibre often consists of a polyurethane block copolymer in which the molecules have a highly coiled structure. Other materials have highly elastic properties,e.g. special polyesters such as polybutylene terephthalate. These materials are used in swimwear, support garments such as athletics garments, skiwear, leotards and increasingly in comfort stretch general clothing. Garments constructed from elastanes give good shape retention and muscular support. Although elastanes may be used bare, they are often covered with a non-elastic yarn.

In reality the design of garments or other items of equipment has a highly significant effect on mobility.
