Semi Worsted Cashmere Henley. Tubular jersey knit neckline. Full length sleeves. Center front placket with button closures. Ribbed tubular jersey knit sleeve cuffs. Tubular jersey knit bottom hem. Semi Worsted Cashmere (CSW) yarn is made by combing the cashmere fibers before spinning them into yarn to ensure that the fibers all run parallel to each other and lie in the same direction. This creates a yarn that is smoother and more compact than regular woolen cashmere, creating a more substantial body that has greater recovery and less pilling.
