The U.S. NAVY SUBMARINE JACKET, formally known as the Coat, Winter, Woolen, was a wool coat issued specifically to U.S. Navy submarine personnel who were considered an elite unit within the Navy. Designed for use in the confined, cold environments aboard submarines, it emphasized functionality and mobility, while also serving as a symbol of distinction from other naval divisions.

The Real McCoy's have reproduced this unique piece to the highest standards using a double-cloth herringbone wool, which is a durable, lightweight, and water-repellent fabric widely used in both military and civilian workwear before WWII. The jacket stands out for its rare black coloration, setting it apart from the standard navy blue issued garments. Though officially listed in the 1941 U.S. Navy uniform regulations, photographic evidence suggests that variants were already in use by the mid-1930s. Due to limited production for pre-war submarine crews, original examples are extremely rare.

The jacket's design is intentionally understated, featuring two large patch pockets and a high stand collar with a functional chin strap for additional protection against the cold. Over time, the herringbone weave develops a more visible texture.
