Only works with Tilley T4MO-1 Hiker's Hat because of the mesh secrete pocket in the hat.

How to use your HyperKewl™ Evaporative Insert:
  • Submerge the insert in cold clear water for up to 5 minutes, wipe away excess water and insert into the hat.
  • The airflow through the mesh panel in the Hikers hat 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-conditioner on your head – it will super charge the natural evaporation process to help you feel comfortable on the trail. High humidity will diminish the fabric’s ability to evaporate water.
  • Re-activate by following the steps as needed.
Fit: For Hikers hats only.
