Ergodyne Chill Its 6700 Cooling Bandana, Evaporative Polymer Crystals for Cooling Relief, Tie for Adjustable Fit, Blue

I got these to help cool me off while at work. I'm so happy with the product that I'm glad I got the 6pk so I could give some to a couple of my coworkers who work a physical job and my sister who gets overheated easily. They love these bands too. We like to wear them as headbands with either the cooling part on our forehead to also keep sweat out of our eyes, or tied on top of our heads with the cooling part at the base of skull/top of neck. My sister wears hers around her heck like a tie. They do keep you cooler and when it stops, you can reactivate by just putting it in cool water again for about a minute or so. It never fully evaporates back to flat. Its been 3 days since last used and it's still "gelly" on the inside but still works. Easily adjustable and tie. Comfortable, made of good quality material (like a bandana). I haven't tried washing it at all yet, but I recommend maybe wiping with a slightly damp cleaning cloth so to not ruin it?

Fast shipping, works great, & good deal. Helped my dogs & I survive Vegas summer heat when night & early morning temps are still in the 90's. I soak them & then keep in freezer. They stay cold for up to 2 hrs. Bought 2 sets to stay in rotation. Easy to wash by hand with dish soap & water. I highly recommend. Thank you pro seller!

These are 2 very different products based on the same principle - evaporative cooling. Evaporative cooling works the best in dry climates (think Arizona), and has the least effect in humid climates (think Florida). The Ergodyne Chill-Its 6700 Evaporative Cooling Bandana - Tie The 6700 is similar to most all the other cooling bandanas that contain gel beads which absorb water and release it slowly. There are many of these products on the market and they seem to differ mostly on the amount of absorbent beads they contain. This particular model is more generous bead wise than many. Ergodyne Chill-Its 6700CT Evaporative Cooling Bandana with Cooling Towel Ergodyne Chill-Its 6700CT Evaporative Cooling Bandana with Cooling Towel - Tie, Lime The "CT" is does not contain the absorbent beads, but does have a microfiber towel on the inside of the "bandana" which (supposedly) increases its evaporation rate and therefore its cooling rate. It is much lighter than the 6700 (and all of similar technology), it also"refreshes" much faster. "Which one is better?" is subjective and is largely dependent upon your access to cold water, how long you intend to use it, and how much the excess weight (of the hydrated beads) bothers you. For occasional use you should also consider the tried and true cowboy version of the same concept: the standard cotton bandana dipped in cold water. The 6700 will last by far the longest as moderate cooling properties go. As with all of these genera, they do tend to warm up and their cooling is less pronounced over time (as the day progresses); recommended if you want some all day cooling without refreshing the bandana. The downside is you have a heavy thing around your neck and that it may emit a (very light) slime that some find offensive. The slime is minimal and can be avoided by not overhydrating the "bandana" (think Viagra warning), or freezing it. The 6700CT may be preferred by anyone who is bothered by the weight and/or "slime" of absorbent gel "bandanas" and has more access to cooling water during the day. It seems to stay a little cooler longer than a plain cotton bandana (dipped and wrong out), but not much. hth, high

I absolutely loved this thing when it first arrived. Shocked that the coolness lasted as long as it did. The down side is after a couple of uses it started to stink like the wet rag in a sink. I hand washed it and hanged it to dry 3 days later and it still stinks & it hasn't dried. I can't put it on my head as it will make my hair stink too. I wondered if I could put it in my drier to accelerate the drying process but it says not to and I would be afraid of what it would do to my drier. I even went as far as leaving it in the dashboard of my car so the heat of the car would dry it but that also did not work. It is still damp, cool but stinky. It is really to bad because I loved the low profile of the headband.

Soaks up a LOT of water and feels great at first, but soon warms up and then just basically gets your shirt wet. Viewing this as a problem, I decided to put the soaked neckband in the freezer! Make sure you curl it to your approximate neck size and be certain not to bend it when frozen or you'll rip the fabric. I put mine in the freezer for less than 30 minutes so it wouldn't freeze solid and it worked GREAT! I'd recommend getting two so you can swap them out every so often.

Save your money. There are better alternatives out there. This fabric becomes a gooey mess once you put water on it and activate the beads. Plus, once you have it on all the beads squish to one side, rendering it ineffective.

I am in perimenopause and was looking for something to help me stay cool. I remembered about 30 years ago buying a cool bandana in the golf shop that I worked at. It was all the rage and made such a difference when playing sports. I decided to search on Amazon for something similar and found these! This is exactly the same type of product I used thirty years ago. It works! I know some people have complained about not having enough crystals inside, but you just need to evenly distribute them across the bandana before you submerge it in water. My bandana got really fat and stayed cool around my neck for hours. I didn't have one hot flash the whole time I was wearing it. I think I'll order more!

They work. I use them when I mow.

This is a brilliant, simple idea ....and it works! Keeps you cool and comfortable in any situation wether you are working or holidaying. Just soak it in cold water, gently remove the excess water and it's ready to wear, then repeat as required.

This product is supposed to be a chilling bandanna for hot days. I have an old one and wanted a second one to swap off with due to the current heat wave here. I wetted the bandanna and it did not expand at all as it should have, remained flat. Did not cool at all. Cheap product which does not do what it is supposed to do. I am returning it.

Great cooling neck tie in hot weather. Wet to activate the section with ‘crystals’ inside which then swell up to a gel consistency. Love the bandana print. Have used these in the US (kept cold in ‘fridge or frozen before use).

I bought these for my spouse to use at work. They kept him much cooler on hot days. Work great because his hands are free and he can wear them on his forehead or around his neck. Everyone at his workplace wanted some too.

Fits and works great for long lasting cooling!
