More Information

  • How does it work:
    - Kool Max frozen water-based cooling packs require access to a freezer and offer the highest level of cooling energy.
    - It takes more energy to charge these packs in a freezer and in return, the packs offer greater cooling energy than Cool58 cooling packs.
    - These reusable packs deliver comfortable cooling for up to 3-4 hours
    Note:‚ Cooling times are estimates and will vary depending on climate, body metabolism and activity.
  • Works in any climate - extreme heat and humidity are no problem. The cooling performance is not impacted by humidity or outside temperature.


  • To measure the chest and waist circumference:
    - First, wrap a soft measuring tape around the fullest part of your chest and under your armpits, making sure to keep the tape parallel to the ground. This determines your chest measurement. Then wrap a measuring tape around your natural waistline (usually across your belly button), making sure to keep the tape parallel to the ground. See where the larger of the two measurements fall on the size chart. Please note: The vest circumference is independently adjustable at the chest and waist with hook and loop strap closures. if you think you are in between two sizes, order the next size up to accommodate the cooling packs.
  • To measure the vest length:
    - Hold the tape measure at the highest point of your shoulder. Look straight ahead and pull it down to your natural waist. Mark this measurement on the tape measure with your thumb. Please note: The vest length can be adjusted at the shoulders. When in doubt, order the next size up to accommodate the cooling packs and to prevent the vest from looking too short.
