The airflow through the mesh panel will start the evaporative cooling process. The cooling insert is expected to provide temperatures that are approx. 10 to 15 degrees Fahrenheit cooler than ambient temperature depending on airflow. It will not feel like an air-conditionner on your head – it will super charge the evaporation process to help you feel comfortable on the trail. High humidity will diminish the fabric’s ability to evaporate water.
