Colback (hat)

A colback is a cylindrical fur hat, usually made of black lambskin, worn as part of the dress uniform of certain military units. It is particularly associated with hussars, fusiliers, and other regiments of similar historical origin or affiliation.

The colback's distinguishing feature is a colored bag (often referred to as a flamme or plume bag) which hangs from the top or side of the hat. The color and placement of the bag often indicate the wearer's rank or unit affiliation. This bag is typically made of cloth or similar material.

The colback serves a largely ceremonial purpose in modern military dress. Its origins lie in earlier forms of military headdress that provided some degree of protection, but contemporary versions are primarily symbolic and ornamental, reflecting the historical traditions of the regiment.

Variations in the style and ornamentation of the colback exist depending on the national military tradition and the specific regiment in question. These variations can include differences in the height of the hat, the color and material of the fur, and the design of the plume bag.
