In Central Asia, headgear goes beyond the utilitarian concept of protection against the cold and rough weather. The same applies to other items of clothing. It was a sign of recognition of an ethnic or even family affiliation, and of a social position. The quality of the work was in a way a distinctive sign of the wearer. At the same time, it testified to the dexterity of the female members of the household.
Traditionally, when a man left home, he wore the smallest size, wrapped in a generally white cloth. Only the top of the cap was visible. This turban was not worn in the home. The materials most often used were cotton, silk or felt. The technique might be appliqué or needlework, such as cross-stitch. As well as small headgear, men also wore felt or fur hats.
