HyperKewl 6529-HV-XS MiraCool Cooling Vest, Soak for 3 Min, Cool for 5-10Hr, Lightweight for Hikes, Running,Camping, Outdoors

Ii's simple and effective. Riding the 395 from Los Angeles to Mammoth in the summer when it's 110 on the edge of the Mojave, this did the trick for me. It kept my body from overheating on the road in between pit stops where I would refresh it. In such high temps it's not going to be "comfortable" but it can keep you from developing life threatening hyperthermia. A must have for riders in the southwestern US.

I purchased this vest before a 300+ mile bike ride in hot, humid summer heat and sun. I had overheated on that ride the summer before. The vest works as advertised. At rest stops I dunked the vest in water and put it on over my cycling jersey. When I put the vest on it didn't soak me. It just felt damp. It did make me feel noticeably cooler for sure. I wore it during the ride at one point and the coolness lasted about 1 1/2 hours while riding until the vest started to dry out. I don't recommend carrying the vest on a bike ride unless the ride is supported as it is bulky and gets heavy when wet. It would be great for those working in the heat of the day, or for support vehicles to have for those people who are starting to over heat. (sports teams, work crews) Good value for the price. If you are wondering about sizing, err on the larger side. Even if the vest is a bit large it still works.

I am pleased with the quality. It is substantial, not flimsy, and appears to be well made. I ordered the XL, which is what I normally wear in a T-shirt, and I find the vest to be true to size (my chest measures 44"). I am short (5') so the length hits about hip level on me. The lime green color is easy to see at night, which I consider a nice safety feature. Once saturated, this vest is a little heavy and hard to wring out, so it will drip, and you will get wet. I think it would help to run it through a rinse/spin cycle in the washing machine to help with this issue, but you wouldn't be able to do that if you weren't near a washing machine. It definitely works better at cooling if there is a breeze. I use mine while walking; if you are on a bike you'll get more air movement, even if there is no wind. I am in AZ, so even at night, the temps can be in the 90's, however, humidity is pretty low. I'm not sure how well this would work in a humid climate. I have some of those neck coolers with gel beads that swell up when soaked, and I was using them prior to getting this vest. The vest does not puff up like the neck coolers do, and that is a good thing. Overall, a good product for my purposes.

I had heard good things about these kind of cooling vests so decided to try one out. I am a motorcycle rider and normally take a long meandering ride around the country and Canada each summer so experience some really hot days of riding. This vest has done a great job so far. I left my home town of Naples, FL on June 25 and am now in Washington State headed to Canada. When ever I have put this vest on it has done what it was described to do, which is keep me cool on the hot days. I would recommend this to anyone who wants to feel cooler on any hot day.

Works well, but cooling effect doesn't last as long as stated in ad.

muy buena calidad, si bien todavia no lo probe, tengo unas toallas similares y funcionan muy bien, asi que le tengo fe a este chaleco

Bought as a gift for brother, who does a lot of outside work. I have one myself, and they work quite well on those overly hot summer days when you're working or playing hard. It helps keep you a little safer in extreme heat, and certainly feels better than without' something like this.

Not good for sweaty southwest Florida summers. Just keeps you wet, not cool at all and it is very heavy so you get hotter doing outside tasks like mowing the lawn. Might work in a dry environment like Arizona, but definitely not in a humid environment.
