Ergodyne Chill Its 6700CT Cooling Bandana, Lined with Evaporative PVA Material for Fast Cooling Relief, Tie for Adjustable Fit, Flames, 2-Pack

This item is great for short periods of time. I love that it evaporates instead of 9bsorbing the heat. I only wish it lasted longer.

I love this product, they work great, but the color is fluorescent yellow, *not* lime green!

SUMMARY:Chill-Its 6700CT felt like a stiff wet towel and did not impress. I would pass unless you don't have the time or circumstances to prep a Chill-Its 6700 instead.Chill-Its 6700 provides stellar cooling but feels slimy to the fingertip, albeit not to your neck. Another reviewer suggested hydrating less for less slime but presumably less cooling too. Highly recommended, especially if you are going to be in such hot, sweaty circumstances that you are going to want to shower afterwards anyway. More comfortable than the standard tubular neck wrap too.Huachnet provides moderate cooling and is useful when you are just a little hot or if you have access to water so that you can rewet it. It is colder when wet; cool, clean and dry to the touch after 1 hour of hanging in my laundry room. It contains a good amount of polymer crystals.DETAILS:I already have 3 cooling neck wraps filled with crystals, bought many years ago. 2 of them are in a beautiful pattern and have a wooden bead that I can slide up and down to quickly tighten/loosen the wrap; I would have loved to buy more of these but I don't know where I bought them and cannot find them any longer. The 3rd one, without the bead, did not have as many crystals in it, doesn't plump up much, and runs out of cooling energy quite fast. I decided I should buy a replacement and, seeing as experience had already shown that not all neck wraps are created equal, decided I'd better try to find one with ample crystals.After reading many reviews, I decided to buy "Ergodyne Chill-Its 6700 Evaporative Polymer Cooling Bandana - Tie Closure" because a reviewer explicitly said it had more crystals than most; "Huachnet Cooling Sports Scarf Neck Wrap Headband Ice Scarf Reusable Ice Bandana wristband" because it was pretty; and "Ergodyne Chill-Its 6700CT Evaporative Cooling Bandana - Tie Closure" because I wondered if a different technology might work better.The Chill-Its 6700 and the Huachnet both contained polymer crystals and I put them in a bowl full of cool water for an hour (which is much longer than in the directions but I was busy and got distracted). After an hour, they were both very plump. At first, the Chill-Its seemed much plumper but I realized the gel had not spread out lengthwise; after I squished it out to fill the neck wrap evenly, the Chill-It ended up flatter and wider than the Huachnet. The dimensions of the gel section were Chill-It 16" x 1.75" x 0.5" and Huachnet 15" x 1.25" x 1". The Chill-Its gel was homogenous and the Huachnet gel felt like individual orbs, but I didn't notice any difference when I was actually wearing them later. I thoroughly wetted the Chill-Its 6700CT (15.5" x 2" x 0.25") and then hung all 3 neck wraps up in my laundry room.After 1 hour, I checked on the 3 neck wraps. The 6700 was extremely wet with a surface slime, the Huachnet was dry to the touch but still plump and cool, and the 6700CT felt like a wet towel. I checked every hour for about 6 hours and they stayed like that. Each time I touched the slimy 6700 with a fingertip, I was grossed out by the slime and had to wipe my finger on a paper towel. After 6 hours, I decided to put them on. I actually couldn't bring myself to put on the 6700 because I was grossed out by the slime so I started with the Huachnet.HUACHNET: Dry to the touch, it was easy to put on and provided a moderate cooling. The Huachnet is very similar to the neck wraps I already own. Experience tells me that on a hot day, this will become warm from the heat of your neck fairly quickly but you can take it off and let the heat of your neck dissipate and then it will provide coolness again. If you don't take it off, it becomes a warm annoying thing around your neck. It felt like a heavy tube around my neck which was pretty much what I expected.6700CT: This felt like a wet towel when I touched it and it felt like a wet towel around my neck. Not impressive. I didn't think it would have a very long cooling effect.6700: Finally, I wiped the 6700 with a paper towel to try to get some of the slime off (didn't help) and then gritted my teeth and put it on. It was ICY! And my neck didn't care about the sliminess at all. I kept it on for awhile and the 6700 cooled me down and remained cold the entire time. It was flatter than the Huachnet and I think that the increased surface area helped with the cooling effect and it definitely felt more comfortable (no tube effect) around my neck. When I took it off, my neck was slimy and I wiped off with a wet paper towel. Note that the reviewer who said that the 6700 had more crystals than average also warned of the slime and said the effect would be reduced by not overhydrating the crystals; if I soak it for a shorter amount of time, it seems likely that I won't have so much slime.

These things are what they look like. A little rag that you dampen and wrap around your neck. I think they do help for awhile. There are precious few ways to keep cool when you are working out in the sun. These help a little and are real simple to use.

They work pretty good. Not the best but pretty damn good. I recommend them if you’re working in the summer heat, under a sun hat!

The idea is there but for the job it was needed for, these cool neck ties did not perform well. Yes they work but I needed something that was able to stay cool for a long period of time and to cover a larger area of flesh to help remain cool and not overheat. During the summer, a commercial kitchen can reach upwards toward 90 degrees. Still looking for that perfect item-

Works good while wet. It stopped sweat going into my eyes.

Not too bulky

Wore this to a festival in the thick of summer and it was helpful with staying cool. I would say it really only stayed cool for maybe an hour but it was easy enough to just pour more water on it and put it back on.

These were absolutely perfect for my son's football camp. When I found out that he would be practicing in heat I bought these to keep him cool during training drills. 10 out of 10 perfection. They do dry up like the reviews say to be like a cardboard sriffness however that's not a deterrent for me because you only use them when they're wet. Good for pets or hiking or just a hot day too!

It keeps the sweat off for about an hour before rewetting. Gets really hard when dry but does soften when water is reapplied. No real cooling effect. Wouldn't buy again.

Only used once so not sure will need to use more.

Good for summer outdoor activities.
