Where is the origin of Panama hat?

The origin of Panama hats is actually Ecuador, not Panama. They are traditionally woven in Ecuador, and have been for centuries. The hats were originally made for local use, but eventually became popular among travelers and traders, who brought them to other parts of the world, including Panama. The hats became associated with Panama because they were often sold there to travelers, who then took them back to their home countries. Despite the name, the majority of Panama hats are made in Ecuador.
