Thank you for viewing. This is a GR Racing jumper. The size is M, but it's a European size, so it feels like a size L. It's new and unused, but it has been stored at home, so please refrain from purchasing if you are sensitive to this. Width: 53cm, Length: 75cm, Shoulder width: 44cm, Sleeve length: 64cm (Please note that there may be some errors due to amateur measurements.) Returns and exchanges are not accepted. Thank you. ☆ We also have other GR Racing items for sale, so please take a look if you'd like.
