IZOD golf wear. It's labeled as size M, but the fit is large, so I think it's equivalent to a size L. Measurements taken flat: Shoulder width: 47cm Width: 54.5cm Back length: 71cm Please compare these measurements with your own clothes before purchasing. Although it's unused, it seems to have gotten dirty during storage. It might come out with washing, but please be aware of this. Please refrain from price negotiations. No comments needed, immediate purchase is welcome!
