I am selling this item because I bought it at a used clothing store last year but never had a chance to wear it. It is an American-made Adidas track jacket. There is no size notation, but it feels like a size M. For those who understand used clothing, how about it? Size Length: 66cm Width: 60.5cm Sleeve length: 90.7cm Shoulder width: Not measurable due to raglan sleeves *Please note that there may be some errors due to amateur measurements.
