This is a Karl Helmut thick jersey jacket. Although it's not visible from the outside, mesh material is used on part of the back. I quite like it and have worn it many times, so it has a fair amount of wear, but there's no major damage and I think it's still perfectly usable (^^) 【Material】 100% Cotton Mesh: 100% Polyester 【Color】 Black 【Size】 M 【Measurements (flat lay)】 Shoulder width: 47cm Body width: 53cm Length: 74cm Sleeve length: 58cm *Please forgive any slight errors as these are amateur measurements. There are no noticeable stains, but please understand that this is a used item. Thank you for looking.
