It's like having air-conditioning on your bike!
Riding to Sturgis this summer? Or riding on Route 66? If you're on a bike, and it's over 80 degrees, you better get one of these! It's like having air-conditioning on a motorcycle. Put it in a ziploc bag fill it with 2 gallons of water and put it on. It will last about an hour when riding your motorcycle in 90+ degree weather. The all you have to do is turn into the next rest area, put you vest in a 1 gallon ziploc, bag and fill it up. It will take more than a gallon to soak it up and you'll be surprised how much water it holds. After an hours ride, you're dry! (except for the crotch in your Levi's) LOL

Works great when there's wind
This vest works like it says - by evaporative cooling. This makes it great for any situation where there's a breeze; otherwise it will feel wet and clammy if you're just standing around with no wind. Very effective when riding a motorcycle - it saved me through 6hr of 112 deg heat in the southwest. As for size - I take XL shirts but the XL vest was loose over my t-shirt so I'd say it runs large. I still wear a vented jacket over it which keeps it in contact with my skin and works as designed. Very light weight and comfortable and the price is right for something you are going to wear occasionally.

Keeps me cool in the summer.
I recently purchased this Evaporative cooling vest and I'm really impressed with its performance. The quality is excellent, and it's very easy to use. I've been using it on and off for about a month, and it has consistently met my expectations. One of the standout features is the way it cools you down, while allitle heavy when it is full you can ring some of the water out and make it just perfect. It has made a significant difference in my experience of being out doors or riding my motorcycle, While there are a few areas where it could be improved, overall, I would highly recommend this product to others. The quality is very nice the Zipper works great. It's a great value for the price, and I'm glad I made the purchase. I've written several reviews on Amazon, and I try to be as detailed and helpful as possible for other shoppers in making informed decisions

Worth the money.
Worked great. Requires a lot of water (gallon at least). You will be wet. I used this today (98 degrees according to the Harley) and no problems. It stayed cool until it was dry (about two hours) then it was a hot. I wet the vest at a convenience store and it went right back to cool. Here again, a bottle of water will not be enough water, it takes at least a gallon to activate the vest and you will be wet (but cool). Feels well made, not cheap. Zipper is nice and large (plastic) and did not hang up or stick. The back comes down off the neck which is ok with me but it does not cool the neck - upper back and below. No interference with my helmet. The front is open to mid-chest allowing some air flow down the front after the vest dries (positive) and the sides are open except for an elastic band (no cooling material on the side) but I did see this as a positive once the vest dries. The vest did not flap in the wind, it stays put and somewhat rigid when wet. After the vest dries it floats around a little but not to the point of a problem. Vest weight is around two lbs dry, water is 8.2 lbs per gallon so the vest starts out heavy and gets lighter as it dries. Size seems right, no bunching or gathering, bottom landed right in my lap as I sat on the bike. Kept my core covered and cool, front and back. Remember, everywhere this touches will be wet, so pants and shirt will be a little more than damp.

Decent if your expectations are realistic
I've had this vest for about 6 weeks, so it's seen a lot of 100 degree days. I use it just for commuting and sub-2 hour rides, as it loses it's effectiveness after that. I typically don't use it unless temps are well into the 90s. Does keep your core noticeably cooler for a while and only takes a few minutes to "activate". On the downside, to really work well as long as possible on really hot days, you really have to soak it. This makes it heavy, and your shirt underneath will get wet, as will the top of your pants or shorts, and probably your underwear as well. I find this an acceptable tradeoff to keep somewhat comfortable, but others may not. Evaporative vests like this supposedly work best in low humidity, so if you live where there's a "dry" heat, you may have better results. Sizing seems true, so make sure you get the size that provides you with a comfortably snug fit under your jacket to get the most benefit. It's also handy when running errands on hot days, since it helps keep you from overheating while walking around in stores with gear on. For the price and what it's designed to do, I think it's a good investment. The only reason I gave it just three stars is the construction quality concerns me, since there are a few areas with stitching flaws that look like they could cause trouble later on.

Fit and performance review from hot weather biker
Let me start with the fit. I'm 5'10", 155 lbs, 40" chest, male, and ordered a medium, and that's a good fit. It's got breathing room, but not too big. Now for the performance. I've been on two rides since purchasing. First day was an hour long ride at 95 degrees fahrenheit, high humidity, 2 lane highway speeds for about an hour. Was also wearing full face helmet, denim jeans, leather vest. I definitely stayed cooler than I would have without it. Second ride was at 100+ degrees, high humidity, freeway speeds for about two hours. Other safety gear was the same. Again, I stayed noticeably cooler than I would have without the evaporative vest. I did not fully saturate the vest, and it had just about dried at the two hour mark. The vest chafes just a bit around the neck, but it's not a problem, just an observation. Also, note that the vest works through evaporative cooling. This means that your torso will get wet. It also means that the vest will be noticeably heavier when wet. This should be expected... just sharing for folks who may not have considered this. Definitely will use again.

Cold and Wet
This vest does what it is intended to do, keep you cold during super hot days while working in the scolding sun. However, while it is mentioned that the vest can be damp due to how you're supposed to make it cool, lords forbid it rains when you wear it. It will be like wearing a large sock over your clothes. You will be kept just warm enough to not keel over, but cold and wet enough to feel like a slimy foot in the winter. It also takes forever to dry once it has been absolutely drenched from the skies waves of fat rain. I've had mine hang above my bathtub in the hopes that it will be dry enough to put back on, but alas- That took days, to nearly a week of trying to hang dry it. Besides it's soggy nature, good vest. (Tldr, vest good, does its job, fear the rain.)

I recommend
I was skeptical first of how will this work... But iam service engineer and was a desk worker befow who lives in AC now I can work under the sun In the summer and iam sensitive to heat.... It really reduced feeling of heat ALOT in summer under 45 degree combined with very large fiahing hat Downside that it will make ur shirt little wet but when u take it off it will dry in sun or AC for 10 - 15 minutes or u can get a spare shirt.... I would be honest it is not like staying in AC but in this temperature under the sun and very high humidity it is a life saver Overall very impressed and I still recommend

UN PLUS POUR LE CONFORT SOUS LES FORTES CHALEURS
Je roule à moto dans le Gard (FRANCE) sous le soleil et après avoir trempé ce gilet dans l'eau froide, le laisser échapper le surplus d'eau, je l'enfile sur un T-shirt sous la veste moto . . . Enfin, une régulation de ma température corporelle. . . fini de transpirer à grosses gouttes de sueur dans les embarras de circulation . . . L'effet de refroidissement dure jusqu'à 3 heures c'est selon le type de randonnée à moto et les conditions météos. Trouver une source d'eau froide ne pose aucune difficulté puisqu'il faut aussi abreuver en carburant le 2 roues. Conclusion : super achat qui améliore l'attention et donc la sécurité du conducteur puisque celui-ci n'est pas "anesthésié" par la chaleur du Sud. A RECOMMANDER.
