Elastane (also known as spandex or Lycra) is a synthetic fibre with exceptional elasticity: it can stretch several times its length and return to its original shape. Elastane is almost never used pure — it is added in a small amount (a few per cent) to other fabrics to give them stretch, good fit and the ability to hold their shape. It is precisely thanks to elastane that jeans hug the figure, sports and swimwear cling perfectly, and knitwear does not stretch out. The fibre was invented in 1958 and made a genuine revolution in the comfort of clothing. Elastane does not crease, is light and durable. It is the 'invisible hero' of the modern wardrobe — rarely the main material, but the one that gives freedom of movement, comfort and a perfect fit to almost any piece.
