This is one great sun hat.  Yet the mesh crown keeps the top of my head cool.  One point of caution.  Be aware that if you order the XXX-l size, it's really spacious.  I normally wear a 7-7/8 hat but this XXX-l size is more like an 8 or even bigger.  I was able to adjust the sweat band with some paper strips so it would fit.  If you ain't got a super large head don't order this size.
