The sombrero vueltiao 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.
