Ingredient
Elastane (13%)
What is Elastane (13%)?
Elastane is a synthetic fiber known for its exceptional elasticity. It's composed of a long-chain polymer called polyurethane, which is produced by reacting a polyester or polyether with diisocyanate. The result is a highly stretchable material that's used in many garments.
Elastane is commonly used in clothing like leggings and sports bras to provide comfort and flexibility. While there are no significant health concerns associated with its use in clothing, elastane fibers can cause skin irritation in some individuals, particularly those with sensitive skin.
When you see elastane on a clothing label, it indicates the garment will have stretch properties, offering a snug and flexible fit. This can enhance comfort and performance, especially in active or athletic wear.
Commonly found in: Leggings, Sports Bras, Swimwear, Athletic Wear, Underwear
What to watch
- Some individuals may experience skin irritation from prolonged contact with elastane.
Benefits
- Elastane provides excellent stretch and recovery, making clothing more comfortable and form-fitting.
The FDA does not regulate elastane, as it is used in textiles rather than food or drugs.
Elastane is generally considered safe in textiles, with limited research on any direct health effects except for minor skin irritation.
Elastane is a synthetic fiber and does not involve animal-derived ingredients, making it suitable for vegans.

Scout's take
Synthetic polyurethane stretch fiber. Suspected primary BPA carrier in athletic wear — commonly used as a polymerization catalyst or antioxidant during elastane production. Continuously sheds microplastics during washing.
More from Scout's analyses
Synthetic polyurethane stretch fiber. 13% is a relatively high spandex load for performance fabric. Continuously sheds microplastics during wear and washing. Combined with the nylon, the garment is 100% synthetic — no biodegradable content.
