The Akubra hat is a distinctive part of Australian culture. Claimed to be derived from an Indigenous Australian word, Akubra is the company name of one of Australia's most famous producers of hats, although the name tends to be used more often to describe the hats themselves. Indeed, the company's range of hats is so large - and so ubiquitous - that in Australia nearly any hat of a similar design is likely to be mistakenly referred to as an Akubra. Akubra"

A barretina is a traditional catalan hat that was frequently worn by men, especially in the countryside, until the 19th century. It is a hat in the form of a bag, made of wool, usually red, or sometimes purple. Today, use of the barretina is uncommon in everyday life, but is still used in folklore dances, or as a symbol of catalan identity. Salvador Dalí popularized the barretina in recent times. The catalan Christmas figure caganer also wears a barretina. Barretina"

The biretta is a square cap with three ridges or peaks (four for those who hold Doctorates of Sacred Theology or STD), surmounted by a tuft, traditionally worn by Roman Catholic clergy, as well as by some clergy of the Anglican Churches. Historically, the biretta was used by all ranks of the clergy from Cardinals to priests and deacons. It is also part of the Court dress of Advocates in the Channel Islands. Contrary to public opinion, the biretta has not been abolished as a result of changes in regulation of clerical dress and vesture following the Second Vatican Council, but it has fallen into a state of disuse, and is therefore most commonly seen in use by clerics of episcopal rank on occasions where its use is mandated by church rubrics.

The end of this bag was attached to the right shoulder as a defense against sword-cuts. In Great Britain busbies are of two kinds: (a) the hussar busby, cylindrical in shape, with a bag; this is worn by hussars and the Royal Horse Artillery; (b) the rifle busby, a, folding cap of astrachan (curly lambswool), in shape somewhat resembling a Glengarry but taller. Both have straight plumes in the front of the headdress. Busby"
