Slouch hat
（重定向自Bush hat）
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, Germany and many others. Australia has had a slouch as standard issue headwear since the late Victorian Era.
