The best way to use any cooling product is to use it before you overheat. The trick to not overheating is keeping your core temperature from rising too high. Use your UnderCool Cooling Vest before you do something strenuous or before you go out into the heat. Then use it in the heat or during any activity that makes you sweat. 

Post-cooling is often overlooked, but using your UnderCool Cooling Vest to help bring your core temp back to a normal range promotes less fatigue and faster recovery.

  1. Before going into the heat or participating in strenuous activity.
  2. During activity or exposure to the heat.
  3. Cooling down after for faster recovery.
