This one will be misunderstood by many and loved by many more. It may be original shape of the wrongly called "Panama" hat, a classic one that has many names as Optimo and Colonial. This will be the kind of hat you want if you have heard or read the stories about rolling or folding straw hats, still it will be under your own risk but because of its shape it will be easier to go back to the original form.
