Wikipedia
A slouch hat is a wide-brimmed felt or cloth hat most commonly worn as part of a military uniform, often, although not always, with a chinstrap. It is a survivor of the felt hats worn by certain 18th century armies. Since then, the slouch hat has been worn by military personnel from many different nations including Australia, Britain, India, New Zealand, Southern Rhodesia, France, the United States, the Confederate States, Germany and many others. Australia has had a slouch as standard issue headwear since the late Victorian era.
Today it is worn by military personnel from a number of countries, although it is primarily associated with Australia, where it is considered to be a national symbol. The distinctive Australian slouch hat, sometimes called an "Australian bush hat" or "digger hat", has one side of the brim turned up or pinned to the side of the hat with a Rising Sun Badge in order to allow a rifle to be slung over the shoulder.
In the United States it was also called the Kossuth hat, after Lajos Kossuth. During the American Civil War (1861–65) the headgear was common among both Confederate and Union troops in the Western Theater, although not always with its brim turned up at the side. During the Spanish–American War, as commander of the Rough Riders, Colonel Theodore Roosevelt became known for wearing a slouch hat.
