ErgodyneErgodyne Chill-Its 6665 Evaporative Cooling Vest - Lime, Large

Maybe the problem is my expectations, but having never bought cooling gear before I expected a bit more. What I received was a vest that says it has polyester and cotton in it in the materials tag on the vest. There's no mention of PVA anywhere, and I realize now that the "activated polymer inside" doesn't actually specify what type of plastic they talk about in this vest.So, essentially, this is a cotton T-shirt wrapped in a layer of plastic on the outside.The expectation was that it would soak in water to its core and leave the surface at most clammy. This thing is soaking wet on the outside even after you wring it dry after immersion, and the water flows down and when the top is dry-ish, the hem is dripping. So, I can only assume this isn't in any way a "high-tech" vest with PVA that soaks up a lot of water and slowly releases it to get the cooling effect.. It's a bog standard cotton-polyester vest that you can soak in water.I bought a Chill-its hat alongside this. That clearly states it does have PVA in the sweatband. And the sweatband in the hat is clearly different to the vest - it's cold and somewhat clammy feeling without feeling wet. That is what I expected from the vest, but this vest appears to have none of this more unusual material in it, making it lower tech and I suppose mildly better than just wearing a wet T-shirt. Disappointing. It will cool you down, I'm sure, but at the cost of also soaking through your clothing most likely Caveat Emptor.

Can't really, as a present for my daughter and won't come into full use until next summer.

This vest is a necessity for those who react to heat in a negative.A great aide for my wife who has MS

This vest works well, I'm not experiencing the sliminess others have, it lasts about 3 hrs in temps over 110 degrees.I've used this vest many times now and recommend it.Good quality and a great price.It does make a few damp spots in your shirt but leaves no stains.No more heat exhaustion and that in itself makes it a worthy buy.I wear a XXL shirt but the vest fits perfectly in xl size.Zipper is plastic but of good quality.A metal Zipper would rust over time and rust will cause stains

This product is absolutely amazing. It keeps me cool for hours and very easy to get it cool again. You don’t have to wear those bulky water packs that when they thaw you still have to carry the weight. Anyone looking for a vest to keep cool this is the perfect choice! I had an issue where the bottom fabric of the zipper ripped. Customer service got back to me very quickly and solved my problem right away. I would give 10 stars if I could. Don’t think about it or look for other products. JUST BUY IT!!!

My husband said it works well and keeps his cool in the Arizona heat

It gets the job done but might be heavy for certain types of outdoor activities. Recommend soak it, ring it out , then put it in the freezer over night. Lasts a few hours be f ore chilling is needed again.
