I was hoping that these hats were a true sun hat, using SPF protection materials. They are not! Contrary to the description stating that they are a cotton/polyester material, all three are labeled as 100% cotton, and it is a stiff cotton. The crown of the cap has a weird shape and doesn't fit comfortably at all. I own another true sun hat and the material is lightweight and the bill is longer that normal. This cap is nothing like that at all.
