Size 7 1/2. Actual measurements: ● Inner circumference: 62 cm. *Actual size, approximately L to XL. This is a reproduction of the US ARMY M-37 denim hat by YMCL KY. It's a reproduction of the denim hat used by the US ARMY from the 1930s to the 1940s. Vintage versions are highly sought after and expensive, with larger sizes being scarce. This is a reproduction sold around the 1990s, and I think it's well-made. Finding a vintage one in the right size is difficult, so a reproduction is a practical option. The condition is good, and it's a beautiful item with relatively little wear. There are no particular areas of concern, but it is a used item, so please purchase only if you understand this. YMCL KY.
