The N-1 Deck Jacket was introduced in World War II, replacing the Pea Coat in all but formal situations due to its improved practicality. The N-1 system was a three-piece, cold-weather system that included a helmet and overalls, but the Deck Jacket was often matched by sailors with other climate systems, like the N-2 and the N-3, to suit their preferences and service conditions.

The N-1 Deck Jacket had experimental iterations in Navy Blue and with clasp closures, but ultimately the U.S. Navy settled on the Button & Zip Closure N-1 Khaki, which was widely cherished by deck crew, who would often wear their N-1 beyond service. The N-1 Deck Jacket was phased out after the Korean War, but modern systems are heavily influenced by this seminal piece.

The N-1 DECK JACKET / SPECIAL EDITION goes beyond traditional military specifications and utilizes an extra heavy cotton corduroy shell, finished with a soft sheepskin collar, as opposed to the classic alpaca collar. Though scarcely seen, vintage garments have been discovered with non-spec collars such as mouton. Maintaining the distinctive lining in alpaca, this wool acts as an incredibly effective insulator with the unique property of remaining warm when wet. The N-1 DECK JACKET / SPECIAL EDITION is finished with a 40s bell-shaped front zipper in brass and wool ribbed cuffs.
