Nylon spandex legging bra fabric combines 80–85% nylon and 15–20% spandex, offering exceptional stretch (up to 500% elasticity) and shape retention for snug yet comfortable support. The blend ensures durability, moisture-wicking, and breathability, ideal for high-movement activities like yoga or running. Its interlock or knit structure resists pilling and maintains smoothness against the skin, while 4-way stretch enhances flexibility. Common in seamless designs, it supports compression for muscle stability and adapts to body contours without chafing. Innovations include UPF 50+, antimicrobial treatments, and recycled variants for sustainability. Lightweight (200–300gsm) and machine-washable, it balances performance, comfort, and long-term wear.
