In 1937, the troopers' uniforms were similar to today's. They wore French blue shirts and blouses, French blue caps, and black Sam Browne belts and holsters. In the winter, they wore boots and boot breeches. In the summer, they wore slacks with a French blue stripe on each leg.
In 1947, "Ike" jackets, named for a style General Dwight D. Eisenhower made popular during World War II, replaced the blouse. In the 1950s, blouses and open-collared shirts replaced the Ike jacket, and troopers began wearing semi-western gray straw hats in the summer. The summer of 1964 must have been hot: the agency allowed short-sleeved shirts for the first time and started purchasing patrol cars with air conditioning.
Today, troopers wear slacks, shirts, and a dark blue campaign hat throughout the year. The blouse is for dress occasions, and a work jacket is optional.
