The Evaporative Cooling Brimmed Hat.
This is the hat that uses evaporation to keep your head up to 30° F cooler than outside air temperature. The hat works by first running it under cool water and shaking off the excess. Its 100% polyester microfiber suede conducts body heat outward, while retaining the cool water and releasing it slowly through evaporation, cooling your head. Its ventilated crown also provides cooling. With a suede cinch and braided cord around the wide 3" brim. It also provides a sun protection rating of UPF 50+--the highest possible--and its wide 3" brim protects your face and neck from the sun's harmful UV rays. Imported. Khaki. Sizes M (7-7 1/8), L (7 1/4-7 3/8), XL (7 1/2-7 5/8), or XXL (7 3/4-7 7/8). (2 oz.)
