The warp is made of 80/1 ultrafine cotton, and the weft is woven with processed nylon and polyester yarns. The difference in shrinkage between cotton and synthetic fibers produces a crepe wrinkle effect, and the material is extremely light and thin, with good stretchability and quick-drying properties. The yarn itself has moisture absorbency, so the jacket does not become stuffy and can be worn comfortably even in summer. Elastic shirring at the cuffs and hem. Placket connected to the armhole prevents itself from coming out when the front is opened.
