This is an XL size, and the color is dark gray. MUJI Inner Down, Collarless I used it for about a month and a half, but I was careful not to get it on my neck or wrists, so it's very clean. I wore it over sweatshirts and thick flannel shirts, so there's no sweat stains. I'm selling it because I don't think I'll be wearing inner down this year either. The item itself is relatively new and I think it's clean. I've marked the images with a red pen, so please check the manufacturing year and model number. Made in '23. There's no unpleasant storage smell, it's clean. Color: Dark Gray
