The bamboo polyester fabric, which is a 50/50 blend of bamboo, which regulates unpleasant heat and trapped moisture, and polyester, which has excellent quick-drying and durability, has excellent water absorption and moisture absorption, creating a comfortable environment inside the clothing. In a humid environment, the more moisture the fibers contain, the more comfortable the feel, and in a chilly environment, the less moisture the fibers absorb, the more moisture they retain. The difference in moisture content between these two environments represents the performance of regulating the environment inside the clothing according to the environment, and it has been proven to lead to comfort. The figure below is a chart comparing the moisture content of the fibers in a humid environment (temperature 30 degrees Celsius, humidity 90%) and a comfortable humidity environment (temperature 20 degrees Celsius, humidity 65%). Bamboo polyester maintains an appropriate moisture content in both environments, has superior moisture absorption compared to 100% polyester fabric, and also has moisture-regulating performance that keeps the inside of the clothing comfortable. Will be shipped in a thin package without a box via Nekopos.
