HyperKewl Evaporative Cooling Sport Cap

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.

Got this for my wife. She said that it does keep her cooler during runs in the Sacramento heat -- not as much as we thought it would, but enough to be helpful. It also absorbs sweat better than a regular cap.I bought a similar HyperKewl cap in a different style. I had the same reaction: not a miracle, but still worthwhile. We will both keep the caps and continue to use them.

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.

This is a great idea but it doesn't cool for very long on a hot day. If you stop every now and then and cool the hat off with new cool water then it works great. But it doesn't take long for the water to get hot on your head and then you lose the cooling effect. It is a good quality hat and I wear it a lot outside without wetting it because the white fabric helps keep my head cool.

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.

Keeps you nice and cool on hot summer day. I use it for outdoor yard work. Stylish and great looking hat. Remains in tact after wetting and lasts up to 4 hours.

I really wanted this hat to work because it was recommended for patients like me. I live in southern CA which is dry desert climate. This just didn't work for me. It doesn't fit snugly enough against my head. Maybe this hat works better for people who have extremely short hair? Plus, the bill being wet was super unpleasant and difficult to wring out with the rest of the hat to activate the cooling element, so it was dripping water on my face. Returning this.

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.
