The ahg-cool scarf is suitable for any sportive activities and wherever cooling is required. The cooling effect starts as soon as the scarf is placed in water for 4-5 minutes. The polyacrylic granulate inside the scarf absorbs the water, turns into crystallic gel and expands. In connection with body heat the water evaporates from the gel and thus cools. In order to obtain the original condition of the scarf it is simply expose it to sunlight and the gel will dry quickly.
