A very light towel made of material that guarantees a long-lasting cooling effect.Simply soak this towel in water, wring it out lightly and shake it.This activates the fibers and they become cooler than the air due to evaporation.The towel then keeps the temperature 3-5 C cooler than the surrounding environment.For ice cooling, you need to soak a towel in cold/ice water.As long as the towel is sufficiently moist, just shake it again after heating and it will continue to cool.The towel also provides protection against UV radiation and is not chemically treated in any way.It is suitable for cooling down and ensuring thermoregulation in a warm environment, hot weather or during sports activities.The outer layer is made of 100% polyester and thus functions more like a classic towel.
