Ever wonder how evaporative cooling technology works so well?? Here’s the inside story…

The temperature of Clothing can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). The combination of unique fabrics used, creates a water management system. The unique HyperKewl Cooling fabric absorbs, stores and releases water within the multi-layered material. Water is released through evaporation, energy is consumed, and a chill effect is created. The HyperKewl Cooling fabric actually cools the body the same way the body cools itself through evaporation. When the vests are worn over a shirt or uniform – undergarments will remain dry due to the waterproof lining. The item will start cooling immediately and will stay cool for up to 4-10 hours depending on the airflow. HyperKewl™ (CE-certified) products utilizes a unique chemistry to achieve rapid absorption and stable water storage. The chemical formulation also creates enhanced evaporation. Users can expect the evaporative cooling fabric to provide temperatures that are 10-15 degrees Fahrenheit cooler than the ambient temperature, depending on airflow.

Q: Is HyperKewlfabric 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.

  • Simply dunk the item in water for approximately 1 – 2 minutes
  • Gently squeeze out the excess water
  • Wear
