Grade 4 Birdseye Fabric is a high-quality fabric with strong functionality and wide application range, and is one of the bird's eye fabric series. The surface of the fabric has a unique bird's eye texture and is covered with multiple small holes. These holes not only give it a unique appearance, but also significantly enhance the breathability and comfort of the fabric. Through these tiny holes, air can flow freely, effectively regulating body temperature and accelerating sweat evaporation, thus keeping the wearer dry and comfortable during high-intensity exercise or high-temperature environments. Grade 4 Birdseye Fabric also has moisture wicking properties, which can quickly absorb and release sweat to help keep the skin dry. Grade 4 Birdseye Fabric is very suitable for making sports equipment, such as running clothes, yoga pants, fitness clothes, etc., especially for sportswear that requires breathability and moisture wicking functions.
