Sports textiles refer to high-performance textiles designed to support comfort, mobility, and safety for athletes during sports activities. The fabric used in sportswear is mainly developed to provide high performance whilst participating in physical exercises. They are mainly made from primary materials such as polyester, nylon, elastane, and spandex, and are sometimes blended with high-tech materials like Coolmax, Gore-Tex, or carbon-fibers.
Sports textile technologies of today include moisture-wicking finishes, compression engineering, temperature-regulating materials, antimicrobial finishes, and 3D knitting techniques for seamless manufacturing. Such technologies make it possible to control body temperature, minimize muscle exhaustion, and provide protection from injury or UV radiation.

Sports textiles have applications in professional sportswear, fitness clothing, outdoor materials, and sportswear. They find classification under performance sportswear, protective sportswear, accessories, and team sportswear. The key products that fall under sports textiles include compression legwear for muscle support and recovery, sportswear T-shirts that help in the evaporation of sweat, helmets and pads that provide protection through impact-absorbing materials, and base layers that provide warmth during cold sport activities. Sports textiles combine science with design, thus enhancing sports abilities.
