Available only from Hammacher Schlemmer, this is the hat that uses evaporation to keep your head up to 30º 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 for up to between four and seven hours, depending upon conditions. The hat’s patented fabric inner liner retains the cool water where it vaporizes over five hours, the evaporation process naturally drawing heat away from your head, keeping you cool. With a suede cinch and braided cord around the brim, and chin strap. Its wide 3" brim protects your face and neck from the sun’s harmful UV rays. Sizes M (hat size 7-71/8; head circumference 221/2"), L (71/4-73/8; 231/4"), XL (71/2-75/8; 24"), or XXL (73/4-77/8; 247/8"). Imported. Khaki. (2 oz.)
