This is a light and warm shoulder warmer vest. Made of soft fabric, you can wear it to bed. Size: Men's M ※See photos Shoulder width: about 60cm Elastic string on the sides. Color: Grayish navy This is mainly for indoor use and to prevent cold shoulders and neck while sleeping. It's lightly padded and warm. I bought this a few years ago for my husband, who feels the cold easily, but he rarely used it and it has been stored away. It's a used item, but there are no noticeable stains. It has been washed.
