Cooling effect is surprisingly great!
Its a bit heavy but it feels soooo good. It's thick and keeps your head cool for much longer than I anticipated. It fits a bit tight, but that's okay because it stays on, but it can become a little uncomfortable after a while, but you get used to it. It doesn't look great when you're wearing it, but who cares when you need it to stay cool or have a headache. I do love that its large enough you can pull it down over your eyes, incredibly helpful for a migraine. Made from a good quality material too.

Works great at soaking up sweat
Great item to keep sweat of your face and glasses. Soaks up so much sweat that I was surprised by just how much sweat a had to wring out after using it. Never felt hot. Always felt cool on my head.

Good quality and comfortable
These are comfortable. I would have given them a 5 star, but it seems that they dry out too quick after I wet them to keep me cool. I use them whenever I go walking.

Very helpful in the heat
I have used Ergodyne products for some time. Most notably their “wraps” for your neck. (Just bought some more!) This headband is great under my baseball cap when I’m working outside, whether it be working on the house or in the yard. I’m not sure what some people may be expecting with these wraps and headbands. They are intended to help keep you comfortable while out in the heat. No…they won’t stay cool themselves. But they can make a huge difference in keeping you a little bit more comfortable. When they get dry, it’s a sign you need to re-wet them; I always have a spray bottle handy to do that. Plain and simple. They don’t stay cool, but they keep you a bit cooler by retaining the dampness against your skin. I work outside for a few hours several times a week here in FL, and during Summer these days the heat index can be over 100 even in the early evening. These, along with a mister and a lot of water to drink (and sometimes a big industrial fan when there’s no wind), are a huge help. The high humidity can make the dampness in these evaporate after a few hours, so I make sure to re-wet them when I need to.

Not a lot of help
I thought this would be "cooling" while working in the yard but nothing much has changed. It does keep my hair off of my face and it isn't too tight which I worried about. I wear it under my straw gardening hat. Until it is saturated it does stop the sweat running down into my eyes. I haven't wet it down prior to use yet. I'll have to try that on a day I'm not going anywhere because it certainly destroys any hope of looking presentable after. I sweat like crazy and after an hour or so in the heat I come in looking like I was swimming, with or without wearing it.

Great value & it works!
Loved it so much I bought more. I found it very effective as long as it stayed wet. There was no slipping at all and it was very comfortable. Good value!

My Cool happy Grandson
I brought these for my grandson who works in a warehouse. He didn't get them until this week. He was in my family room yelling my name. "Grandma, I want to tell you something." I walked in the room. He said these words to me. These are great. I put them in the freezer last night. It's 2:45 pm and they are still ready. Yes, this is great" Where did you get them from? Thank you for the great product and at reasonable price also.

Soak it in the sink when you wash hands.. it's wonderful
I use this primarily to trap the baby hair while driving. But I also love the cooling affect after soaking it.. it's amazing how that little extra moisture feels so much better in the heat
