Mens Outback Classic Hat

These hats will actively cool you. There are special Hydro Cool crystals stitched into the front of the inner headband of the hat. If you need to cool down simply soak the front section of the headband in water for about 3 minutes – the crystals will absorb and retain the water. Put the hat on and feel the immediate cooling effect. Depending on the temperature the Hydro Cool crystals will keep cooling you for days and are fully re-useable. The Hydro Cool crystals are non-toxic, non-flammable and non-hazardous.
