Why does Chicago PD have checkered hats?

The Story Behind Chicago PD's Iconic Checkered Hats

If you have ever spotted an officer from the Chicago Police Department, you likely noticed the distinct checkered band wrapped around their cap. Far from a simple design choice, this eye-catching pattern carries a rich history connecting the Windy City to classic Scottish police traditions.

The iconic pattern was officially introduced to Chicago officers in May 1967 by Superintendent O.W. Wilson. Known formally as the Sillitoe Tartan, the three-layer checkered band was adopted to make officers instantly recognizable to the public, enhancing visibility and adding a sharp, distinct element to their standard uniform.

The origin of the design dates back to 1932 in Scotland. It was created by Percy J. Sillitoe, the Chief Constable of the Glasgow Police Department, who sought a clearer way to distinguish his officers in busy street crowds. Decades later, Chicago embraced the motif, turning a Scottish law enforcement signature into an enduring symbol of American civic pride.
