Why do they have anzacs slouch hats?

The Anzac slouch hat is a distinctive wide-brimmed hat worn by Australian and New Zealand soldiers, particularly during World War I. Its design includes a unique feature where one side of the brim is pinned up, which helps with visibility and ventilation in hot climates. The hat symbolizes the bravery and camaraderie of the ANZACs (Australian and New Zealand Army Corps) and has become an enduring emblem of national identity and military heritage in both countries.
