Elastane (6%)
What is Elastane (6%)?
Elastane, also known as Spandex or Lycra, is a synthetic fiber known for its exceptional elasticity. It is produced through the polymerization of polyurethane, creating fibers that can be stretched significantly and hold their shape without sagging.
It is commonly used in clothing and textiles to provide stretchability and comfort. While elastane itself is not absorbed by the skin, it can cause irritation or allergic reactions in sensitive individuals.
When you see elastane on a label, it's important to remember that it's meant to improve the flexibility and fit of the garment. It is widely used in activewear and apparel requiring stretch.
Commonly found in: Pants, Leggings, Swimwear, Activewear, Undergarments, Sports bras
What to watch
- May cause skin irritation or allergic reactions in sensitive individuals.
Elastane is not directly regulated by the FDA as it is a material rather than a consumable product.
Scientific studies on elastane focus on its performance in textiles, with no health-related concerns typically reported.

Scout's take
Gives the microrib its drape and slim fit and keeps the knit from bagging out. At 6%, alongside a 94% organic cotton base, it is a functional necessity rather than a source of exposure.
