This is likely a Patagonia shirt made of chamois cloth. The tag is missing, so the size is unknown. Please refer to the actual measurements: Length: 72cm, Width: 60cm, Shoulder width: approximately 52cm. Please allow for some error. The condition is generally faded, giving it a nice vintage look. There is a white stain below the left chest pocket. The size tag is missing. I believe there was also a Patagonia P-tag on the chest pocket, but that has been cut off. I think there are no issues for those who are used to vintage clothing. #patagonia #Patagonia #chamoiscloth #chamois #navy #longsleeveshirt #vintage #usedclothing #llbean #L.L.Bean
