The U.S. NAVY SUBMARINE TROUSERS are made from double-cloth herringbone wool, offering a balance of durability, warmth, and water resistance suited to cold-weather conditions. They are constructed with cotton sewing thread for period accuracy and durability, and feature a nut button fly.

Originally issued to U.S. Navy submariners, the trousers were worn alongside the iconic Submarine Coat. Originally designed for winter patrols and cold environments, these trousers functioned as workwear aboard submarines, where space was limited and mobility was essential. While they were formally documented in the 1941 Naval Uniform Regulations, photographs suggest they were already in use by the mid-1930s. The lightweight herringbone wool used in their construction was considered advanced at the time, valued for its water resistance and strength.
