Worn approximately 10-20 times. The surface is polyester, but it has a wool-like texture and a calm, non-shiny appearance. The color is a light gray, with a darker gray only around the shoulders. The hood is removable, and the zipper is hidden, allowing it to be worn over a suit. The size is S, but it's an import size, so it should fit someone who usually wears a size M. I'm open to a small discount.
