Lets say your out exploring the jungles of Africa, and find that your super sweet old school pith helmet just doesn’t have the airflow that you need to keep you cool. Whatever shall you do? You could always do this.

With cooling abilities far beyond the average sun-shading hat, this is the safari-grade helmet that harnesses the rays of the sun to power a miniature fan that keeps you comfortably cool while at the beach, on a hike, gardening, cheering a sporting event, or any other outdoor activity. The hat has a whisper-quiet motor powered by four compact solar panels on top. In the evening, or on a cloudy day, the fan is powered by two AA batteries (not included). As lighting conditions change, you can easily switch between solar and battery operation with a flip of a switch. Crafted from weather-resistant coated linen straw for reduced weight and the highest degree of breathability. Imported. 5″ H x 11 1/4″ W x 13 1/2″ L. (8 1/2 oz.)
