Pea coat - A pea coat is an outer coat, generally of a navy-coloured heavy wool originally worn by sailors of European navies. Pea coats are characterized by broad lapels, double-breasted fronts, often large wooden or metal buttons, and vertical or slash pockets. A "bridge coat" is a pea coat that extends to the thighs, and is a uniform exclusively for officers and Chief Petty Officers. The "reefer" is for officers only, and is identical to the basic design but usually has gold buttons and epaulettes. The pea coat was named after the warm woollen fabric called "pij" that the Dutch used to make their sailor's jackets.The pea coat is the coat shape of the season.
