Thank you for viewing. This is a masterpiece rider's jacket from 2-D-Live. 2-way Wire is inserted into the collar, allowing it to stand up and maintain its shape. Although there are no tags, it has been carefully preserved and is like new. Size 3 is a rare size that is still easy to wear! Equivalent to a brand's L size. Slim fits were common back then... It has a double zip, so you can relax by opening the hem. For motorcycles, leather ultimately has limited usage conditions, so I thought cotton would be better and bought this. Actual measurements: Pit to pit: 53-53.5 cm Shoulder width: 43-43.5 cm Sleeve length: 66 cm, 24.5 cm to the center of the short sleeve zip Length: 63 cm, about the size of a modern M! The quality tag is also clean. Size: M
