Cooling towel is made of super ice hyper-evaporative breathable material. Working on the physical evaporation of moisture, no chemicals are used in the making of the cooling towels. It's amazingly easy to pack away and take with you anywhere such as hanging in a bag. Soak for 1 minute, wring out excess water, snap it few times and is ready to use. To reactivate cooling effect, simply repeat the steps. Machine washable for easy cleaning.
