This is the cap that uses evaporation to keep your head up to 20 degrees 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.

4-1/2" H x 7" W x 10" D. (4 oz.)

  1. Cool - ing review by mrfudd2

    Purchased this cap for summer wear and tried it already.
    Feels like it will work just fine and dandy.
    I'm not accustomed to wearing anything on my head but this should keep me cooler in the heat.
    Purchased mainly for travelling to Italy next May.

  2. Evaporative hat review by Emcg

    I gave as gift to husband. He tried it and found it dried very fast and did not have any cooling effect on very hot days
