Issued during 1943–1945, the U.S. Navy N-3 utility uniform in Olive Drab color No.7 replaced earlier chambray shirts, offering better concealment and practicality in the field. Part of full N-3 set, including HBT jacket, pants, shirt, and matching cap, this shirt was issued to shore parties, construction battalions, amphibious units, and security personnel.
Crafted from Japanese 6.5 oz plain cotton with high yarn density, the shirt is smooth to the touch and comfortable for long wear. Its clean, tailored cut ensures a neat silhouette while allowing ease of movement. Lightweight and breathable, the N-3 shirt is suitable for hot or humid climates, combining historical authenticity with practical wearability.
