Elastic material used in the fabrics of a summer cycling attire comprising a jersey, bib shorts and gloves. Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont. [1] [2] [3] Yarn of colourless to white Spandex fibers
Nylon is a fibre used to imitate silk; it is used in the production of pantyhose. Thicker nylon fibres are used in rope and outdoor clothing. Spandex (trade name Lycra) is a polyurethane product that can be made tight-fitting without impeding movement.
A lycra jacket. Stretch fabric is a synthetic fabric that stretches. Stretch fabrics are either 2-way stretch or 4-way stretch. 2-way stretch fabrics stretch in one direction, usually from selvedge to selvedge (but can be in other directions depending on the knit). 4-way stretch fabrics, such as spandex, stretches in both directions, crosswise and lengthwise.

Speedo claims that their LZR Racer reduced drag or water resistance by 38% compared to a traditional Lycra practice swim suit. [1] This high-technology swimwear is designed to minimize drag while maximizing support to muscles. [1] Some companies claim that their fabrics reduce drag even more than the water's normal friction against the skin.
