I live in Cali and it gets 120* over the summer. My daughter never goes outside without a hat. But her hair has gotten so long and curly that I needed to buy her a visor. Although I like the shape of this hat, she was sweating bullets because the material doesnt breath. I like the adjustable brim and how you can tighten it on the inside as well. But since it is some form nylon instead of cotton, Im not sure if this will be functional where we live. Im bummed.
