HyperKewl Plus is a combination of specialized fabric and fibers which utilizes a unique chemistry to achieve rabid absorption, stable water storage, and enhanced evaporation.

All of our evaporative cooling products use HyperKewl technology which can provide an average cooling of 10-15°F/6-8°C cooler than the ambient temperature (depending on airflow).


HyperKewl™PLUS fabric absorbs and then slowly releases water through evaporation.

When the water evaporates, energy is consumed, and a cooling effect is created.

We look at this as supercharging the body’s natural cooling process.


It’s easy to activate. Just soak in water. Squeeze out the excess and you’re all set.

Enjoy 5-10 hours of cooling power*.


HyperKewl™PLUS fabric is machine washable up to 104°F/40°c.

Our Evaporative Cooling fabric continues to work for up to 150 wet/dry cycles.

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.Pumped Water Cooling Shirts

These are the most advanced and the coolest of the cooling vests.  Based on technology developed by NASA, these shirts work by circulating cool water through non-kink tubing around the wearer’s body.  As this water moves through the system it takes the heat away from the body cooling you down.   This water then flows back through the System Unit to a reserve of ice cold water.  The circulating water automatically cools before being re-circulated around the vest.

  • Come in different power options including 12v, battery and standard outlet.
  • Provide a cooler temperature than both evaporative and phase changing cooling vests.
  • Works in high humidity.
  • Available as shirts and vests
  • Can be used as rehabilitation stations for construction workers or emergency services

Frequently Asked Questions


Q: Is HyperKewl Cooling fabric safe?
A: Yes. It contains non-toxic polymer. See our MSDS under "Documents".

Q: How does it work?
A: Our HyperKewl is sewn into the lining of all our garments. The special fabric absorbs water very quickly and releases it very slowly for extended cooling from evaporation.

Q: How long do I hydrate the garments?
A: 1-2 minutes.

Q: What is the lifespan of the HyperKewl products?
A: HyperKewl fabric is designed to provide up to 100 wet/dry cycles.  Water absorbency will diminish over time as HyperKewl fibers migrate and entangle within the fabric structure.  You may see an initial decline in the absorption of water after 5-10 wet/dry cycles as the fabric "settles," but absorbency will remain relatively stable after this initial 5-10 wet/dry cycles.  This is normal and the fabric is still very effective at water absorption and evaporation.  Absorbency will also be impacted by hydration length, garment care, water quality, as well as other factors.

Q: How much will the items weigh?
A: You control the weight of your garment by how long you hydrate it.  Our #6529 Sport Cooling Vest will weigh approximately 750 grams after a 2 minute soaking.

Q: Can I silk screen and/or embroider the products?
A: We recommend embroidery.

Q: How can I wash the garments?
A: In order to maintain the longest life of the product and HyperKewl Cooling fabric it is best to hand wash the garments with a gentle soap and brush.  Avoid soaking the garments in soapy water.  Simply use the brush to wash off the garment.


Q: What temperature is the Phase Change Material (PCM)?
A: A comfortable 14 degrees C.

Q: How do you activate PCM?
A: Solidify the inserts by placing them in a fridge, freezer, or ice water.

Q: How long does it take to activate them?
A: Approximately 30 minutes.

Q: How much does PCM weigh?
A: PCM is 25% lighter than water.

Q: Is PCM safe?
A: Yes, it is non-toxic, non-carcinogenic, and non-flammable.

Q: Is PCM reusable?
A: Yes, the inserts can be re-activated over and over again.

Q: How long will the PCM stay activated?
A: Vest inserts will remain at 14 degrees C for up to 3 hours.

Q: How can I wash the inserts and clothing?
A: The inserts can be wiped off with a cloth.  They are made of polyurethane and are very durable.  Do not use sharp objects as the inserts could be punctured.  The clothing can be washed as per normal washing instructions for cotton or poly/cotton.  Remove the inserts before washing.
