Hat band

A hat is a head covering which is worn for various reasons, including protection against the elements, ceremonial reasons such as university graduation, religious reasons, safety, or as a fashion accessory. In the past, hats were an indicator of social status. In the military, hats may denote nationality, branch of service, rank, and/or regiment. Police typically wear distinctive hats such as peaked caps or brimmed hats, such as those worn by the Royal Canadian Mounted Police. Some hats have a protective function. As examples, the hard hat protects construction workers' heads from injury by falling objects and a British police Custodian helmet protects the officer's head, a sun hat shades the face and shoulders from the sun, a cowboy hat protects against sun and rain and a Ushanka fur hat with fold-down earflaps keeps the head and ears warm. Some hats are worn for ceremonial purposes, such as the mortarboard, which is worn (or carried) during university graduation ceremonies. Some hats are worn by members of a certain profession, such as the Toque worn by chefs. Some hats have religious functions, such as the mitres worn by Bishops and the turban worn by Sikhs.

While there are not many official records of hats before 3,000 BC, they probably were commonplace before that. Archaeologists think that the Venus of Brassempouy from 26,000 years ago may depict a hat. One of the earliest known confirmed hats was worn by a bronze age man (nicknamed Ötzi) whose body (including his hat) was found frozen in a mountain between Austria and Italy, where he'd been since around 3,300 BC. He was found wearing bearskin cap with a chin strap, made of several hides stitched together, essentially resembling a Russian fur hat without the flaps.
