I didn't wear it much before it became too small. It's made of sweatshirt material and is well-made. Size: 130 The color is a light gray. In the summer, you can wear it as is or with short sleeves, and if you layer a long sleeve underneath, you can use it for a long period of time＾＾ There are no noticeable stains, but please understand that this is a used item before purchasing m(_ _)m
