Nón Ba tầm is a traditional Vietnamese flat palm hat. It should be distinguished from other traditional Vietnamese headwear such as the conical nón lá and the coiled turban, khăn vấn.
Nón Ba tầm is traditionally worn by women in Vietnam, as an accessory to finer garments, as opposed to the more functional clothes associated with farm work. Until the early 20th century, this hat was widespread in Northern Vietnam.
The hats worn by shamans, traditionally had silver ornaments hanging from silk strings around the brim.
