  1. 40 years of air conditioned comfort 5 Star Review

    Posted by on 8th May 2017

    As a machinist with 40 years of working on close tolerance parts in temperature and humidity controlled shops I started working in a shop that is open and subject to all of that great Maryland/DC heat and humidity. I started last year near the end of summer and knew I had to do something or my spoiled self was going to suffer. I researched different vests and really liked what I saw with STACOOL VESTS. I made the purchase and put it to the test. I can say that my world is going to be VERY COOL from here on out. I tried one reviewers idea of wearing it over a T-shirt and agree that it is most comfortable that way. I hand stitched our company patch over the vest so I could be "Uniform Compliant" and some of my coworkers asked me which Boss gave me the product. I told them "The Smartest One" and told them to order their own and they too could STACOOL and smart like me!

  2. Very help 4 Star Review

    Posted by on 8th Aug 2016

    We purchased this vest for our son with special needs. He is heat intolerant and does not sweat. We just recently got the vest and so far it has been good. It actually works like a weighed vest for him as well due to the weight of the ice packs. Not too heavy though. We did have to switch sizes as he measured for an XXS but we returned it for an XS. It fits nicely and the customer service was wonderful! Hope to use it for many years.

  3. Product is a big help, customer service is great 5 Star Review

    Posted by on 5th Aug 2016

    This vest does what it claims: keep your body temperature down. I suffer from cholinergic urticaria (heat hives). When I'm outside on a hot day, sitting in a poorly air-conditioned office, or severely stressed, I break out in hives. What an awful feeling! It's truly embarrassing to, in a public place, start pouring water on myself to get cool. I needed a better solution.

    StaCool's under vest seems to be doing the trick. The gel packs were fairly easy to hydrate, and they slipped very easily into the vest. (That's no small thing. With other brands, it was almost impossible to get the gel packs to fit right.)

    Here are a few other notes, in case they're helpful to prospective buyers:

    - I'm 5'10, 155 lbs. Every shirt I own is a MEDIUM. Since the cooling vest is meant to be a snug fit, I ordered one size down (SMALL). I was shocked to discover it was still too big and that I needed an EXTRA SMALL.

    - I wear an undershirt beneath the vest---not because it's too cold, but because the undershirt helps hold it in place.

    - This vest is more concealable than its competitors, but I can still see the back of it jutting out beneath my shirt. That doesn't bother me, though. Being cool's better than feeling cool!

    - StaCool's customer service is excellent. They 1) answered questions over the phone before I bought my vest; 2) provided me electronic copies of the gel pack instructions when I misplaced my print copies; and 3) allowed me to exchange my vest for a different size.

    I'm very happy with my vest as well as StaCool's customer service. They've got a customer for life!

  4. Love it! 5 Star Review

    I finally received my vest. I tried it this weekend and I loved it!

  5. "Cool" vest! 5 Star Review

    Posted by on 15th Jun 2016

    I bought this vest to help me with my heat intolerance related to MS. I have worn in at my job teaching Physical Education outside. It kept me cool for almost 3 hours. It's not too cold, but it does a good job of keeping my body temperature down. The other day I got really hot in my house and I put the vest on and within a few minutes my body cooled down tremendously. I also love the cool style of the vest. That's what help me determine which ice vest to purchase. It's very comfortable to wear and very easy to put the ice packs in. I definitely recommend this vest.

  6. Vest fits great and is very comfortable 4 Star Review

    Posted by on 20th Nov 2015

    Vest is a nice product. wish it had a quicker way to dry than drip dry. I can only afford the one at present and it is not quite dry when I start out. Although I guess you could say it adds to the cool for the first hour of wearing.

  7. Helps for MS management 4 Star Review

    Posted by on 3rd Aug 2015

    I have MS, and got the cooling vest on the advice of my medical case manager for outdoor summer use. I wore it last weekend to our grandsons' outdoor birthday celebration - an afternoon picnic on a very warm day - and was able to comfortably participate for a few hours. It's both lightweight and comfortable to wear. This was an excellent purchase for me.

  8. good for Texas 4 Star Review

    Posted by on 12th Jul 2015

    Tried it today while working in what feels like over 100*F. Marvelous.

  9. Great way to beat the heat 4 Star Review

    Posted by on 6th Jul 2015

    I purchased this vest to wear while I ride my motorcycle in the Arizona summer. I tried it under a mesh jacket at first but it only lasted about an hour that way. I now wear it under a closed and zipped up jacket now to hold in the cold, it worked this way for about 3 hours. I am only using 2 ice packs in the front because all 4 are a bit heavy and bulky under a close fitting jacket. It keeps my core temp nice and cool and have made riding in 110 degree heat bearable. I would recommend this product.

  10. Easy To Use and Effective at what it does 4 Star Review

    Posted by on 16th Jun 2015

    This is the only cooling vest I have ever purchased and I went into it with some skepticism and a slightly incorrect mindset about what these things did. I do not have MS, I just wanted one to wear in the 90 degree weather in direct sun when I am working on lines(telephone pole wires).
    The vest is comfortable enough. It pinches around the neck a little and doesn't extend as far down the back as I think it should but it fits very well. They tell you before check out that if you dont know what size to get, get the one lower than your size because you want/need the vest to fit snuggly. This is not only because you want the vest comfortable, but because you want the vest flush against you to feel the cold. If you don't get the right fit the vest might not work properly, or at least you won't feel cool.
    Feeling cool is the wrong mindset I mentioned earlier. Don't think of these vests as the one stop fix to make you feel like you're in AC when the temperature around you is mid 80's. The extra set they give you is wonderful to have on hand to swap out when you feel the gel packs starting to lose their cool. Bonus points if you have a freezer at your work to keep cycling them. All 8 packs, depending on your freezer, can take up quite a bit of space.
    The cooling power of the vest is very nice. I had difficulty with deciding if it was cooling me down enough or not at first. This is partly due to the gel packs being safer and not being as cold as ice, and partly due to the fact that bodies acclimate. Acclimation can be tricky because you will begin to think the vest isn't doing it's job because the skin its been sitting on is used to being chilled. Twist the vest to either side if you need to find out if it's still cooling you; and often times it is, no matter how hard your brain might try to trick you.
    That being said THIS IS NOT THE COLDEST VEST
    Steele makes colder vests with cooler icepacks. The problem with these is that they can actually be too cold for some people, and definitely too cold and too bulky to wear directly on skin or in a concealable way. The Stacool Under vest is very concealable; the first day I wore it to work no one noticed it under my t-shirt.
    All in all this is a wonderful vest that I would recommend. You just have to research all the available ones and find the ones that fit your climate and activities. This is definitely the best effective concealable vest for it's price range.
    (First Line Tech makes what most would call the perfect vest but at a much steeper price.)
    (Steele makes the coldest most durable but zero conceal ability and possibly too cold for some.)
    (Koolmax is the cheapest. Conceal ability, comfort, and ease of use take a back seat.)
    (StaCool makes light, safe vests that get the job done and can be concealed fairly well while maintaining safety, comfort, and an affordable price range.)
