This hat has been awarded a rating of UPF 50+ which means that you will be protected from almost 100% of the harmful UVA and UVB rays. (We recommend that you still use sun screen for maximum protection.) Far superior to a straw hat, our braided hats have a wide soft elastic inside the brim which makes them fit comfortably. "Monica" is a blend of natural color and darker beige color fibers that give it a nice textured look. Fits medium size heads 57cm to 58cm.
