My Barmah canvas Drover has helped me survive some of the hottest destinations on earth.  In the past 3 years, I have worn this hat on hikes in the Arizona desert, to the rainforests of Panama and Costa Rica, through Italy in the heat of August, to the equator and the Galapagos Islands, and through Israel and the dead sea basin.  I just ordered another from RodeoBeach -- not because my first one is worn out, but because I want a second one in another color.  You cannot go wrong with this hat!!
