The Built-In Solar Hat Fan could very well become a summer staple for people who can't stand the seasonal heat waves. As its name succinctly gives away, it boasts a built-in fan that is powered by solar panels. Resting in the brim shading the wearer's face from the sun, the fan blows down cool air to ensure that he or she doesn't succumb to the hot day before them.
Developed by Thanko, the Built-In Solar Hat Fan may not be the most stylish accessory o the market, but if it prevents heatstroke, that shouldn't matter in the least. Available in four colors (red, yellow, blue and black), it is is size adjustable between 53 to 58 centimeters.
