This is the perfect sunscreen hat, and for me with a larger head, it fit just right.  It's made of a stretchy straw material, has a strap (needed on a windy day), a nice 4.5 wide brim all the way around which really keeps the sun totally off my face.  I have received more compliments on this hat!  Well made, great price.  I bought two, just in case I couldn't find it again when my first one wore out.  Highly recommended, terrific ,sunscreen protection hat!  Update 11/15 -  the hat being shown here is not one of the hat I bought.  They have the wrong picture up now. The one I purchased is brown and black, made out of a delicate straw like material.
