Undercover Sleeve-Switching Jacket The sleeves are made of leather with a USED finish. The leather sleeves are soft, and the jacket is light overall, so you can wear it casually anytime. The sleeve ribbing is also finished with leather. Size 3 Width: Approximately 55cm Length: Approximately 66.5cm Raglan sleeves, so shoulder width and sleeve length cannot be measured. It has been used, but it has been worn with care, so I think it can still be worn.
