This is a POLO SPORT MA-1. I think it's one of the most serious models in Ralph Lauren's military sampling. Vintage US military originals often have the problem of being too short in length, but this one is designed with a silhouette that's easy to wear as streetwear. It's very well made. There's a small scuff on the back. It hasn't gone through the fabric. The collar ribbing is slightly stretched. Size: M Actual Measurements: Shoulder width: 51cm Sleeve length: 65cm Length: 67cm Width: 67cm Thank you.
