The sombrero vueltiao (Colombian Spanish for turned hat) is a traditional hat from Colombia and one of its symbols. It is made out of Gynerium sagittatum known locally as caña flecha, a type of cane that grows in the region. The word vueltiao is a Colombian regionalism from the northern Caribbean Region and the area surrounding the Magdalena River basin that originate in the word for "turn" or "lap" (Spanish vuelta), and arose due to the way the hat is made. The quality of the hat is determined by the number of pairs of fibers braided together to make the hat, and its bending flexibility. The more flexible the hat is, the higher quality it is.
