What is Elastane (15%)?

Elastane, also known as spandex or Lycra, is a synthetic fiber known for its exceptional elasticity. It is created through a chemical process involving polyurethane, which results in a fiber that can stretch significantly yet return to its original shape.

Elastane is used in clothing to provide stretch and comfort, particularly in form-fitting garments like leggings and bras. There is no substantial evidence indicating that elastane itself poses significant health risks when used in apparel.

When you see elastane listed on a label, it usually indicates that the clothing item will have enhanced flexibility and fit. This material is commonly appreciated for its comfort and durability in activewear and everyday apparel.
