HyperKewl Evaporative Cooling: This simple and effective technology works by combining water with our HyperKewl Fabric to create garments that gradually release water through evaporation to keep you cool, but comfortable. Typical applications include industrial safety, construction, emergency services, military, outdoor recreation, athletics, motorcycling and equine.

Who are cooling vests for?

At The Warming Store we have cooling vests available for a range of activities and uses.

  • Construction workers, gardeners and anyone else who works outside during the summer
  • Military personnel
  • People suffering from medical conditions with heat sensitivity
  • Motorcyclists
  • Sportsmen and sportswomen
  • Emergency Services
  • Anyone who wants to enjoy the summer without being overwhelmed by heat


How do they work?

We have 3 styles of cooling vests which work in different ways to help you keep your cool.


Evaporative Cooling Vest

These use the natural effect of evaporation to cool you down.  When these vests are placed into water the specially made non-toxic  material absorbs hundreds of times its weight in water.  This stored water is then slowly released.  In hot areas this water will start to evaporate.  As it does it the heat from the wearer is transferred into the air helping to reduce your temperature.

  • Light weight.
  • Easy to use throughout the day.  If it dries out all you have to do is submerge in to water for hours more cooling.
  • No electricity is required making them perfect for people on the move.
  • The most affordable form of cooling vest.

Phase Changing Vests

These non-toxic vests have a large pocket front and back in which a refrigerated, frozen, water or air conditioned cooled pack can be inserted.  This flexible cooled pack will then help reduce the wearers’ temperature for up to 4 hours.  These inserts can be refrozen as and when necessary.  Each vest comes with one set of packs.  For all day cooling we suggest ordering extra packs which can be kept in a freezer or cooler until it is necessary to exchange them.

  • Hard wearing.
  • Works in high humidity.
  • Each cool pack can be reused.
  • Does not produce condensation.
  • Typically provides a cooler temperature than evaporative cooling vests.

I umpire in the hot sun and had a tournament with temps 100 everyday. I would not have made it without this wonderful product. It seemed to knock 10 degrees off the temperature around me. I ordered a second one for my brother upon my return. You can't go wrong for the price even if you only use it once in a while.

Nice for extreme hot weather!

Quite comfortable, just be sure to maybe order a little tight to go against a soft wicking shirt. I ordered a large and I needed a medium to keep it tight against me.

Effective cooling
July 6, 2020
Just got back from a 10-day motorcycle trip through western Colorado where the temperatures were frequently in the upper 90s. I wore the cooling vest over a moisture-wicking T-shirt, under my textile motorcycle jacket (lots of air flow). I only had to wear it for about the last hour or two each day, but it did a great job of keeping me cool. I could soak it down in the sink in a gas station restroom and it would still be working when we got to the hotel later in the afternoon. Definitely better than the cheap cooling vest that I got from CycleGear a few years ago.

Lifesaver for horseback riding in the South
June 19, 2019
I questioned whether this would be effective in the South, since the humidity can reduce evaporative cooling. However, when riding my horses, it is highly effective, even when humidity is off the charts, since I am moving while on the horse. The dampness only lasts two hours, even when riding under cover, but that’s enough to make the hot, humid, very long summers endurable.
  • Effective
  • Needs to be re-wet after two hours

Just what I was looking for. Personally, don't like wearing vests but this one is a cheaper alternative that works.

Love this vest!

It does have 1 con, but I didn't want to drop it down to a 4 star because it fits and works so well. I like that I can wear it next to my skin, under a light summer top, although it would probably be OK on top of a tee shirt. The main negative is that when you wear it next to your skin, the zipper tends to irritate a bit - they should have put a flap on material underneath the zipper. Actually, with the stretchy sides, I don't think it really needs a zipper at all. Also, it would be nice to have it lighter -colored versions, like off white or light tan, so it wouldn't be obvious under light-colored clothing. I plan to take it with me when I travel to Indonesia next year, since it's hot there the year round and I start getting unhappy when the thermometer hits 72* F.

Nice addition for warm weather riding
October 20, 2016
I bought this cooling shirt for riding across the Mojave Desert during the Motorcycle Cannonball. It was perfect! I didn't wet it down at first because the morning was a little cool. Late morning I stripped it off, wet it in a sink, put a mesh jacket on, and headed across the desert. I wish I had discovered this thing YEARS ago! This thing is perfect for anyone riding motorcycles in hot weather. I would highly recommend it. However, I had to bump up a couple of sizes from what I normally wear--I know it's supposed to fit tight, but I didn't want it fitting THAT tight.
  • Works incredibly well. Not too pricey
  • Runs small
