Spandex material, also known as Lycra (5 letters), is a synthetic fiber that is lightweight, stretchy, and durable. It is often used to make clothing items such as swimwear, sportswear, and lingerie due to its ability to fit the body snugly and comfortably. Spandex material is also used in medical braces and orthopedic supports. It is highly resistant to chlorine, perspiration, and body oils, making it an ideal choice for activewear.
