This is a U.S. military issue utility shirt, the "OG-507." It's a standard piece loved by many military fans, dating from the late 1980s (made in 1987). Compared to the previous model, the OG-107 (100% cotton), this shirt uses a "DURA PRESS" fabric, a polyester blend, making it less prone to losing its shape and giving it a smooth feel. It also resists wrinkles after washing, making it very suitable for daily use. The deep olive green color remains beautiful, and it's in a plain state without any noticeable patch marks. Because of its simplicity, it's a versatile military shirt that fits any style. 【Details】 • Era: 1980s (made in 1987) • Material: 50% Polyester / 50% Cotton • Color: Olive Green (OG-507) • Specifications: U.S. military issue (DLA100-87-C marking) 【Size】 Marked Size: 15 1/2 × 31 Actual measurements are as follows: • Shoulder width: 45cm • Body width: 55cm • Length: 79cm • Sleeve length: 57cm ※ Please forgive any slight errors due to amateur measurements. 【Condition】 It's in mint condition with little wear, close to deadstock.
