DON'T BE A HOT HEAD! COOLING CAP keeps your head comfortable under the warmest conditions. Just soak the baseball-style cotton cap in cold water—the thermal lining stays cool for hours; keeps your head up to 20° cooler than the outdoor temperature. Washable. One size fits most; has adjustable back.
Love it!! Keeps my head cool from the sun.
I give it about a 6 out of 10. Not bad. Need to use it more to see.
