This is a nylon and sweatshirt combination. - Color: Gray The size is XXL, but it fits slim. I think it's like L to XL. It doesn't look bulky even when worn over a T-shirt. It feels just right, like wearing a thin sweatshirt. Reference: 172cm, 75kg The nylon part has stains, although they are not very noticeable. See photo 6. Thank you for looking.
