This is a riders jacket from ISAMU KATAYAMA BACKLASH. The item is used, so there is some overall wear and tear. The wrinkles in the armholes were reportedly created by Mr. Katayama himself. There is no major damage. It is a sample item, so there is no quality label, but it is the same as the items sold. (Please refrain from bidding if you are sensitive to this or are looking for a new item.) It is definitely authentic. White leather that is not product-dyed is rare for BACKLASH, I think. It is very soft and can be worn lightly. Size 3 Length: Approximately 65cm Shoulder width: Approximately 44cm Sleeve length: Approximately 62cm Width: Approximately 51cm (Please note that there may be some errors due to amateur measurements.) The material is leather (I think it's goat).
