I purchased this hat for a trip out to the Grand Canyon. It has an extra large brim which will keep the sun off of my face and the back of my neck. I have fair skin and I get sunburn easily. In addition I won't have to put sunscreen on my forehead because of the large brim, and the dark color underneath reduces reflective glare.
The quality is excellent, the brim holds its shape. This is the first sun hat that really keeps your head cool. Highly recommend to buy it. You get what you pay for.
