The Trekmates Cool Radial Hat has amazing cooling crystals sown into the front of the headband. Soak your cap in cold water and these magic crystals will absorb the water and keep you cool for days before drying ready to be soaked all over again. You can even put the Radial hat in the freezer or fridge to keep you cooler even longer. This hat is quick drying, breathable and will also protect you from UV rays, making it a truly outstanding summer hat.
This is an old style and Cooling Crystals may not perform.
