Does anyone know anything about Panama hats from Ultrafino Panama Hat Company online. They have a couple of hat that I like. The Venicia Gambler Panama and the Fedora Safari Panama. Both have a 3"-3 1/2" brim and are in the $125 price range. They don't say what type of sweatband they have. I am looking for a good quality hat for sun protection in the hot months. I have a nice Stetson but it is to hot in the summer. Is a leather sweatband an indication of a quality hat vs cotton or twill?
