Olive M1941-Inspired Knit Jeep Hat

The Jeep Hat began as the U.S. Army’s “Cap, Wool, Knit, M1941,” a short-billed knit cap issued during World War II. It was designed as a warming layer beneath the standard steel helmet, where the low profile, knit lower, and small visor could add warmth without getting in the way.

From helmet liner to hunting hat

After the war, surplus examples moved into garages, farm trucks, deer camps, and duck blinds. The same details that worked beneath a helmet made sense in cold-weather hunting: a knit body pulled low over the ears, a short bill that kept sun and weather out of the eyes, and a shape that stayed close to the head. The design later picked up the nickname “Radar Hat” after Radar O’Reilly wore one on M*A*S*H.

The Olive Jeep Hat keeps that field form in a quiet military color. The upper is made from 100% polyester with polyester insulation. A 100% acrylic knit lower holds warmth around the head and ears, while the moldable short bill can be shaped to the wearer’s preference.

It is a simple cold-weather hat with a long working life behind it, ready for the woods, marsh, camp, or the drive in before daylight.
