N1 Jacket - Light OliveOriginally issued to US Navy crew in the mid 1940s, the N1 deck jacket design was in use by the military until the 1960s, becoming one of the longest serving US military uniform styles ever. Universal Works interpreted the N1 jacket with a simplified construction, contemporary fit, and button flap chest pocket finished in a durable cotton twill and filled with insulating polyester to see you through winter. Based on mid 1940s US Navy N1 deck jackets
