The sombrero vueltiao is Colombia's national hat — handwoven from caña flecha grass by the Sinú indigenous people of the Caribbean Coast (the heritage Sinú region around Tuchín and Sampués). The hat takes 7-30 days to weave depending on the number of vueltas (turns) — the higher the number, the higher the quality. A sombrero vueltiao 19 (the highest grade) sells for COP 500,000+ ($120+); a basic 15-vuelta starts at COP 80,000 ($20). Pack: a real sombrero vueltiao is a Colombian-heritage souvenir; verify hand-woven (not machine-made) at Artesanías de Colombia (the government-certified crafts store).
