Around 1900, the bucket hat or fishing hat was introduced. Normally, this bucket hat is made up of tweed cloth, or wool felt. At that time, it was mostly worn by the Irish farmers and fishermen traditionally.
It gives great protection to the farmers and fishermen from rain. The reason is that there is raw wool or unwashed wool used in the manufacturing of these hats, which makes them naturally waterproof.
These Irish walking hats were then adopted for country pursuits in the interwar years internationally. The reason is that they could fit inside the coat when folded. Most surprisingly, if this hat fell in the mud, it can be easily cleaned with a damp sponge. Moreover, it can also be reshaped by using the steam from a kettle.
The members of the mod subculture also wore the bucket hat in 1960.
If we talk about the modern bucket hat, it is made from a tropical hat made from olive drab cotton. That olive drab cotton was firstly issued to the US army during the Vietnam War. Most amazingly, these bucket hats are very lightweight. They are popular among civilians for sun protection as well as for use in sports such as fishing.
