6700CT

My son is wearing a cooling cap purchased from amazon so he wears this around his neck and he says this really helps to keep him cool just wet and ringout and your ready to go!

This is exactly what I was looking for! The Ergodyne Chill-Its 6700CT Cooling Bandana with PVA material is a total lifesaver in this Florida heat. I go on 2.5-mile walks daily, and this keeps me cool the entire time.Pros:Amazing PVA cooling materialLong-lasting relief (hours!)Fun skull designPerfect length & fitPairs well with other PVA gearSuper easy to use!Great Value!Cons:None—this one’s perfect for meThe PVA cooling material is where the magic happens—it lasts for hours, especially when positioned at the back of my head (where I sweat the most). It reactivates easily with water and stays cool even in brutal humidity.The black skull design is awesome—fun, bold, and different. The tie length is perfect, not too short or too long, and super easy to adjust for comfort.Pair this with the company’s cooling vest and towels (yes, I own them all!) and you’ve got a whole cooling system that actually works.

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).Ergodyne Chill-Its 6700CT Evaporative Cooling Bandana with Cooling Towel (this product).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).The Ergodyne Chill-Its 6700 Evaporative Cooling Bandana - TieErgodyne Chill-Its 6700 Evaporative Cooling Bandana - Tie, Solid BlueThe 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."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 potential "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

It ties in the back and it’s wider than I thought. It makes your hair really wet. Men might like it but not women.

My husband wears this when cutting grass and playing golf. He says they really help with keeping him cooler

Not sure why this gets good reviews. I used it this weekend for the first during the protests. Didn't keep me cooled down & does not last long. Then washing them by hand to get the sweat off, the blue inside is falling apart. Wish I had stuck with the bandana types that swell with water that I have bought before.

Stayed very cool for a good amount of time and when it got warm, just shoknit around and it got cool again. Used it all summer!

Perfect for working in hot restaurants !!!
