Lycra Elastane (19%)
What is Lycra Elastane (19%)?
Lycra elastane is a synthetic fiber known for its exceptional elasticity. It is commonly made through a chemical reaction involving a polyester and a diisocyanate, creating a polymer that can stretch significantly beyond its original size.
This material is mainly used in textile manufacturing to give garments flexibility and help them retain shape. Health concerns primarily focus on potential skin sensitivities, although such reactions are rare and usually minor.
When you see Lycra elastane on a label, it indicates that the product will have stretch properties, commonly found in activewear like workout shorts and leggings.
Commonly found in: Workout Shorts, Leggings, Swimwear, Underwear, Sports Bras
What to watch
- Some individuals may experience minor skin irritation from synthetic fibers.
Benefits
- Provides excellent elasticity, improving comfort and fit in garments.
The FDA does not specifically regulate Lycra elastane as it is not an ingestible material.
There is limited research on health impacts due to its primary use in textiles, with isolated reports of skin irritation.
Lycra elastane is made from synthetic fibers and is generally considered vegan as it is not derived from animals.

Scout's take
Synthetic polyurethane-based stretch fiber. Confirmed plastic leaching on skin contact during wear, amplified by sweat and body heat during exercise. Adds a second vector of microplastic exposure beyond the nylon base.
