A checked fabric made from yak thread, a rare animal hair. You can feel the high-quality smoothness that is unique to yak. This season's check fabric is woven using three materials: yak, mohair, and cotton. Although it is made of animal hair, it is extremely light and soft, and the characteristics of the fiber make it highly breathable, making it comfortable to wear even in spring and summer. This item is an open-collar short-sleeved type. Punched items are also available.
