- Put on the vest.

4. Operating Instructions
Once the cooling elements are inserted and the vest is adjusted, you can begin using it. The C15 PRO Cooling Elements are designed to provide a comfortable cooling sensation.
- Cooling Duration: The vest provides a cooling effect for approximately 2 to 4 hours. This duration can vary based on external temperature, humidity, activity level, and individual body heat.
- Optimal Use: For best results, use the vest in environments where direct sunlight is minimized, if possible, to prolong the cooling effect.
- Reactivation: When the cooling effect diminishes, remove the elements from the vest and refreeze them as described in Section 3.1. Having a spare set of cooling elements can allow for continuous cooling.
