Chambray shirts were worn as work clothes by U.S.NAVY. The U.S.NAVY chambray shirt, which is beginning to be depleted in the vintage market, attracts many military fans. Inspired by the so-called 50s model used from the late 1940s to the 50s during World War II, it was reissued in Kamakura's original pattern. While following the original details of the time, such as the straight collar that creates a rugged atmosphere, blue buttons in the same color as the shirt fabric, and gusset with red line, the sizing has been upgraded to fit the modern style. Japanese chambray fabric is used, which fades uniquely as it is worn.
