This is a long-sleeved T-shirt from Frisco Choppers. The size is S. The manufacturer is Port & Company, and compared to the old 80s-90s Hanes of the same size, it has a longer length and a looser fit around the arms. For reference, I usually wear an LL (178cm, 74kg), but I was able to wear this. The waist was a bit tight, but the arms had plenty of room. Shoulder width: 41cm Body width: 42cm Sleeve length (from shoulder seam): 64cm Length (from back of neck rib to hem): 61cm Measurements are taken flat. There may be slight variations. It's in excellent condition, having been purchased new and worn only once. Collectors, please consider. No returns accepted.
