Solar Powered Hat Fan
The solar powered hat fan may not be the most chic accessory for your hat, but will keep you cool in summer. A mini photovoltaic panel harvesting enough solar energy to power the fan directly. A clamp allows you to hang from your hat to direct cool air into your face on those unbearable hot summer days. Tailored mount works best with stiff brim hat and a baseball cap. The fan comes in black and white.
