LANSING, Mich. (WOOD) — Michigan State Police troopers will be doing a throwback next year.

Troopers will wear campaign-style hats, last worn by troopers in the early 1920s, to celebrate the department’s 100th anniversary.

The campaign hat is a black straw hat with a clear coat protection.

MSP is one of only six state police agencies across the nation that don’t wear the campaign hats.
