• IS HYPERKEWL™ FABRIC SAFE?

    Yes. It contains non-toxic ingredients. See our Material Safety Data Sheet under our “Science” section for more details.

  • HOW DOES IT WORK?

    Our HyperKewl™ fabric is sewn into the lining of all our HyperKewl™ powered products. The special fabric absorbs water very quickly and releases it very slowly through evaporation for extended cooling.

  • HOW LONG DO I HYDRATE THE GARMENTS?

    Soak the garment for 2-3 minutes. See instruction on the garment for details.

  • WHAT IS THE LIFESPAN OF THE HYPERKEWL™ FABRIC?

    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.

  • CAN THE PRODUCTS BE REUSED?

    Yes. Just make sure you hang them to dry when not in use

  • HOW MUCH WILL THE ITEMS WEIGH?

    You control the weight of your garment by how long you hydrate it. Our #6529 Sport Cooling Vest soaked for about 2 minutes will weigh approximately 750 gram.

  • CAN I SILK SCREEN AND/OR EMBROIDER THE PRODUCTS?

    We recommend embroidery.

  • HOW CAN I WASH THE GARMENTS?

    In order to maintain the longest life of the product and HyperKewl™ fabric it is best to hand wash the garments with a brush and light soap and water. Avoid soaking the garments in soapy water. Simply use the brush to wash off the garment.

  • WHAT IS THE NEW HYPERKEWL™ PLUS FABRIC

    Our new HyperKewl™ PLUS is a completely machine washable cooling fabric designed to work just like our HyperKewl™ fabric. Consider it our next generation cooling fabric.

  • How is it worn? Over clothing, under clothing?

    The Hyperkewl vests rely on evaporative cooling to work so they must be worn over clothing. We recommend thin clothing such as t-shirts or one layer cloth shirts for maximum benefit. If the vest is placed under clothing it just feels like a damp shirt next to the skin and it won't provide much cooling as it is harder for the vest to evaporate if it is underneath anything. Only the Techkewl and Kewlflow technology vests can be worn under clothing and still be effective.

  • So i have a full body chewbacca suit and i was wondering if this would be a good thing to wear under the suit because its really hot lol

    Answer: This particular vest is not, because if it's not exposed to the air it will just make you uncomfortable. We recommend the phase change vests with inserts for anyone wearing a hot costume.

  • How long does it keep cool?

    It stays cool for a few hours at a time. If you are riding in really hot/dry conditions not as much. I would suggest you re-soak at each gas stop for maximum effectiveness. To thoroughly dry the vest back out takes a couple of days I have noticed. When I am done riding I hang it up where it can get air so it can dry effectively. Its super easy to re-soak so can be done in a cash station sink or at a tap.

  • Is there a size chart for these vests?

    Yes please find in the downloads section of the website.

  • If I wear this in winter will it keep me warm if I use hot water?

    It would not keep you warm as it utilizes evaporate cooling. The water is drawn out out the vest as air moves over/thru the material leaving a cooling effect. Vest is damp on the inside and outside after soaking in water. You may be better with a heated vest/jacket.

  • For how long does a Hyperkewl vest stays cool?

    Well I rode 225 miles at 85 mph none stop between fill ups in 107degree heat and I recharged it at each fill up... So it stayed cool between each fill up.

  • Do ice packs go into this vest? This one comments that it keeps cool for 5-6 hours per soaking. Do you have to put the vest in cold water?

    No ice packs. You don't have to use cold water. I do put mine in the fridge sometimes because it get hot where I live and that makes life in the heat more bearable. If it seems to be warm take it off and Shake it real hard. Why that works I don't know.

  • How much does this vest weigh when wet? How long does it stay heavy?

    It isn't as heavy as the others I have tried. Believe me it is such a blessing to have the cooling that it ain't heavy. I would guess a couple of pounds. We are having muggy weather and I use my almost everyday. It gradually evaporates, and after a few hours you need to put it under a faucet or something to "recharge" it. I love mine.

  • Can this be worn underneath clothes, like a uniform?

    I use mine on my 30 mile commute on a motorcycle ......It works best with a T shirt, than the cool vest...and a light, highly vented, jacket allowing lots of air to reach the vest....I would think it would not work as well under a uniform shirt worn for long periods....sooner or later the vest must be hydrated again....depending on the use and humidity.

  • Would this work in a humid factory if a fan is moving air around me?

    It’s going to help, it truly depends on how much air is moving around you. This line of TechNiche vests work by evaporation and the process of evaporation require air circulation to vaporize, similar to wind chill factor. If you have enough air circulation, it will keep you cool. You might want to consider the TechNiche line of Phase Change Vests as they are designed to keep you cool with Phase Change cooling packs. Yes, they’re more expensive, but in your type of environment will be the better body-cooling product.
