This is the cap that uses evaporation to keep your head up to 20º F cooler than outside air temperature. Made by a supplier of cooling apparel to professional cycling teams, Olympic athletes, and the military, the hat is charged by submerging in cool water for one to two minutes, then wringing out the excess. The cap's patented fabric inner liner retains the cool water where it vaporizes over 5-10 hours, the evaporation process naturally drawing heat away from your head, keeping you cool. 100% cotton with 53% polymer/47% cellulose liner. One size fits most; adjustable hook-and-loop back. Hand wash, air dry. Imported. Khaki. 4 1/2" H x 7" W x 10" D. (4 oz.)
The Evaporative Cooling Cap comes with The Hammacher Schlemmer Lifetime Guarantee at no additional charge. If this product ever disappoints you, for any reason, you may return your Hammacher Schlemmer purchase for exchange, credit, or refund.
