HyperKewl Evaporative Cooling Sport Cap

Breathable, good sun protection, lightweight, adjustable hat band. Cooling properties when wet.

Well worth the investment. Works as advertised. I play tennis in South Carolina, 85-90 degrees, sunny, this allows me to carry-on without melting. Simple concept that works. I soak it in ice water prior to heading out, quick wring-out, good to go for at least an hour. Refresh at water fountain and your back in the game! Both wife and I wear one. Only drawback- comes only in the color shown.

Works okay. Obviously not like an AC unit blowing on your head but it's better than nothing. Must re-wet every hour or so, otherwise it just feels like a regular hat. The fit is good, for people who say this hat is too small they must have some very big heads.

These are the best hats for cooling

This works pretty well. It's not so easy to wring out but it does keep your head cool for several hours....even in the desert!

After trying it out this weekend playing at an outdoor music jam I have to say I’m disappointed. Did not keep me cool. Just has you sitting in a wet hat but not really a cooling effect as I had expected. Would not recommend.

This is a stylish and great hat! I love that the black looked the same after soaking in water and when dry so no one could tell it was for cooling. It had a nice cooling effect and lasted a long time. I have a health condition that makes me sensitive to heat and I’m excited to have this option and could find some thing attractive and not bulky. I wore this on a boat tour in 80-85 degree weather for 3 hours and it was still cool when I got home.

Wet this cap and it will help you stay cool. Hat needs to be wet to help you cool off, otherwise it is just a hat.
