This is a green zip-up jacket made with Thermolite Plus. The size is listed as S, but the chest width is 56cm, so I believe it can also be worn by someone who usually wears a size M, and I've listed the size as M. The collar has a built-in hood, and the cuffs can be adjusted with Velcro. It's also padded, so it provides protection against the cold. I'm selling it to clear out my closet. - Brand: HECHTER STUDIO - Material: Thermolite Plus - Color: Green - Design: Zip-up, with pockets Thank you for looking.
