cotton lined and built out of our light 5oz oilskin so it's great in the
tropics where it can dump an inch of rain in 10 minutes, at least you will know

added a built-in leather hat band just to make it a cut above the rest and
added the two large mesh eyelets so there is plenty of air circulation. Brim
