A simple, rugged form and excellent cold-weather protection.

The deck jacket was worn by U.S. Navy ship crew members to protect themselves from strong winds on the deck of a ship.

Made from a thick, high-density cotton material that offers excellent warmth, water resistance, and wind resistance, this jacket features a boa lining blended with alpaca and wool around the neck and throughout the lining, ribbed cuffs to prevent cold air from entering, and a double closure with both a zipper and buttons. A chin strap and drawstring allow it to withstand even harsher conditions.

While deck jackets are strongly associated with the color khaki, the initial N-1 model first issued to the US Navy in 1944 was navy blue, and originals are extremely rare. The color was later changed to khaki in 1945 and was worn by the US Navy until the 1950s. Incidentally, even among khaki jackets, the period can be determined by the "USN" stencil on the chest, or the thickness of the font.

While it may not have the flashy appearance of the M-51, also known as the mod coat, or the MA-1, M-65, or N-3B, which are quintessential military wear, this deck jacket boasts a simple look while still providing excellent cold-weather protection. It's popular not only among military enthusiasts but also among bikers and those who appreciate rugged fashion, and various companies release versions based on the iconic N-1 model.
