Size: M (US size S) Purchased from the official Dortmund online shop, but I'm selling it because I don't plan to wear it. It has a half-zip and two buttons. There's also a pocket on the stomach, so you won't have trouble with storage. *Please refrain from purchasing if you are concerned about even minor details, as it has been stored by a private individual. *When shipping, it will be folded as small as possible.
