As a way of showing team support, Green Bay Packer fans wear which Wisconsin-made product on their heads?

Fans of the Green Bay Packers proudly sport a unique piece of headwear: a bright yellow, triangular foam wedge. This is a nod to Wisconsin's long-standing identity as "America's Dairyland" and its status as a leading producer of dairy products in the United States. The headwear has become so iconic that the fans themselves are affectionately, and officially, known as "Cheeseheads."

Interestingly, the term "Cheesehead" was originally used as a derogatory taunt by rival fans, particularly those from Illinois, to mock Wisconsinites. The tradition of wearing the foam product began in 1987 when a man named Ralph Bruno, inspired by the stuffing from a couch he was reupholstering, burned holes into a piece of foam to resemble Swiss cheese and wore it to a Milwaukee Brewers baseball game.

The hat was an immediate hit and was quickly adopted by the passionate fanbase of the Green Bay Packers. What began as an insult was proudly reclaimed as a symbol of unwavering team loyalty and state pride. Today, the sea of yellow cheese wedges at Lambeau Field is a famous and enduring image in American sports, representing one of the most dedicated fan communities in the world.
