AeroStrong is a breakthrough elastane fiber — 40% lighter and 3× more durable than conventional spandex. Built in America for America's leading apparel brands.
Our proprietary polymer architecture delivers performance that conventional elastane simply can't match — without trade-offs.
40% lighter per denier than standard spandex. Your garments feel weightless while maintaining full stretch and support across every wear.
3× the flex-cycle lifespan. AeroStrong fibers resist degradation from chlorine, heat, oils, and repeated washing — garments that last.
98% elastic recovery ensures garments hold their form wash after wash, wear after wear. No sagging. No bagging. Just consistent fit.
Performs consistently from 20°F to 150°F. Ideal for activewear, outdoor apparel, and garments subjected to high-heat industrial laundering.
Drop-in replacement for conventional elastane. AeroStrong processes on existing circular knit, warp knit, and weaving equipment with zero retooling.
Engineered and manufactured in the USA. Shorter lead times, domestic supply chain reliability, and full OEKO-TEX® Standard 100 certification.
