Beginning tomorrow, Michigan State troopers will be wearing campaign-style hats, last worn by troopers in the early 1920s, to celebrate the department's 100th anniversary in 2017. The majority of state police agencies wear campaign hats: MSP is one of only six that did not wear them. MSP held a vote to see if members wanted to switch back for the 100th anniversary in 2017, and it was approved. The campaign hat is a black straw hat with a clear coat protection. It is a traditional four-dent style with an extra stiff brim. Similar to their current hats, trooper hats include a black braid, sergeants a silver braid and lieutenants and above a gold braid. Hat badges are being reused on the campaign-style hat. When properly fitted, the strap around the back of the head secures the hat to prevent it from being blown away in high winds.
