The Peacoat and the Navies That Wore It into History

The peacoat's name likely derives from the Dutch pijjekker, a coarse pilot cloth jacket worn by Dutch sailors. By the mid-1800s, naval forces across Northern Europe had adopted double-breasted wool jackets as standard cold-weather issue. The fundamental design remained consistent across fleets.

The U.S. Navy version, standardised in the early twentieth century, was constructed from 32-ounce melton wool in navy blue, heavy enough to resist Atlantic winds. The double-breasted front could be buttoned from either side, allowing the wearer to shield the windward side regardless of direction.

Melton explains why the peacoat looks the way it does. The cloth is woven, then milled and felted until the surface fibres lock together, which is why collar and pocket edges can be cut raw without fraying or binding. That density blocks wind rather than trapping air, so the coat is warmer than its weight suggests but does little below freezing without a jumper underneath.

After World War II, surplus peacoats became widely available to civilians. Their compact hip-length made them practical for urban wear. Through On the Waterfront starring Marlon Brando, the peacoat entered the visual vocabulary of mid-century cool.

Surplus buying rewards a little label reading. Pre-1970s United States Navy coats are pure wool and noticeably heavier; later contracts moved to an 80/20 wool and nylon blend, harder-wearing and less pleasant against the skin. The contract number stencilled inside dates the coat, and earlier examples carry ten buttons where later ones carry eight. The buttons themselves repay a look: the standard naval pattern shows a rope-fouled anchor ringed by thirteen stars.

Today producers range from Sterlingwear of Boston, which still holds the U.S. Navy contract, to luxury houses like Saint Laurent (https://www.sterlingwear.com). Genuine naval peacoats are boxy and heavy; fashion versions are slimmer, lighter, with more refined buttons.

The ideal fit allows layering without looking sloppy. Shoulders should sit cleanly, the body close but not restrictive, length at or below the hip bone. Slimmer men benefit from narrower lapels and tapered bodies. Heavier builds should avoid excessive shoulder padding.

Wool quality matters more than brand name. Look for 100-percent melton in at least 24-ounce weight. The lining should be satin or quilted. Anchor buttons in antiqued brass are traditional. Avoid polyester blends which compromise breathability.

A peacoat takes alteration well in one direction and badly in the other. Sides and centre back can be brought in for around £60 to £100, and sleeves shorten easily because there are no cuff buttons or vents. Length is effectively fixed by the pocket position. Store it brushed, on a broad wooden hanger with room either side, and keep cedar in the wardrobe: moth larvae favour undisturbed dark wool, and heavy melton makes a substantial meal.

The peacoat bridges casual and smart, pairs with jeans to tailored trousers, and works in any climate below ten degrees. Own one in navy blue melton, maintain it with brushing and pressing, and it will anchor your cold-weather wardrobe for a decade or longer.
