Kool Breeze solar fan hats keep your head and face cool with a small solar-powered fan built right into the brim. This collection features cowboy, gentleman, Thurman, and hard-hat styles, several with UPF 50+ sun protection. Powered by the sun, the fan runs whenever you are outdoors with no batteries to charge. They are a practical way to stay cooler during yard work, gardening, golf, and long days in the sun.
