The Montecristi hat company provides the original panama hats, crafted from natural palm fiber by hand in Ecuador. These hats are handwoven and hand blocked according to traditional local craft by skilled artisans. They are lightweight and breathe so are the perfect hat to wear in the hot Australian summer. The Bosalino style has a large sized brim of approximately 8 cm - 9 cm in depth. Sizing: We have 5 sizes. 56, 58, 60, 62, 64. If you are in-between sizes when purchasing your panama hat, we always suggest going for the larger size. You can reduce the size to fit your head by using a small safety pin to fasten inside the center- back band, pulling it across itself.
