Essential Info

As the weather continues to heat up, more measures must be taken in order to keep cool while enjoying the outdoors. With an Evaporative Cooling Sport Vest from HyperKewl all it takes is 1-2 minutes of soaking in water to provide temperatures up to 15°-20° cooler than the ambient temperature for several hours. Upon submerging the vest in water, the HyperKewl fabric used will absorb, store and then release water within the vest through evaporation to cool us down. After removing the vest from soaking, excess water should be gently squeezed out and wiped away before wearing. This process can be repeated as often as needed throughout the course of the day to stay cool. The Evaporative Cooling Sport Vest has a wide range of applications such as hiking, working outdoors, sitting in the stands at a ball game or to simply escape the day's heat. The vest has a front zippered closure and a V-neck collar.

  • More Info

    How it Works: HyperKewl fabric absorbs and stores water when it is submerged. Water is then released within the layers of the vest through evaporation to create a chill effect similarly to the way in which our bodies cool themselves through evaporation.

    Instructions for Use: Submerge vest in water for 1-2 minutes, squeeze out excess water, wipe dry and wear.

    Washing: In order to maintain the longest life possible it is best to wash with a gentle soap and brush.

    Note: High humidity (90%+) will diminish the fabrics ability to evaporate water to provide cooling.
