Polyester spandex 4-way stretch knit interlock fabric combines 80–95% polyester and 5–20% spandex, offering multidirectional elasticity (up to 500% stretch) for unrestricted yoga movements. The interlock knitting structure enhances durability, minimizes edge curling, and ensures a smooth, breathable surface. Its moisture-wicking properties keep wearers dry, while the blend resists pilling and maintains shape after repeated use. Ideal for yoga leggings, it supports compression and muscle stability, with optional UPF 50+, antimicrobial treatments, or recycled polyester variants for sustainability. Medium-weight (200–250gsm) and machine-washable, it balances comfort, flexibility, and long-term performance
