What is Spandex?

Spandex is a synthetic fiber known for its exceptional elasticity. It is made from a long chain polymer called polyurethane, which is produced by reacting a polyester with a diisocyanate.

Spandex is used primarily in clothing, including underwear, athletic apparel, swimsuits, and more, due to its ability to stretch and return to its original shape. There are no significant health concerns associated with spandex as it is not ingested and has minimal contact with the skin's surface.

When you see spandex on a label, it's worth noting that it is included to provide comfort and flexibility in the garment. This is especially beneficial in activewear or stretch-fit garments.

Commonly found in: Underwear, Blouses, Shorts, T-Shirts, Sweatshirts, Pants
