Panama Hats are hand-woven in Ecuador from the fine fibers of the Jipijapa palm. Because of their lightness, Panama hats are worn in warm weather and the wide brim provides sun protection. It is said that the name Panama Hat was associated with this head wear because it was worn during the construction of the Panama Canal.
