Abstract The present invention provides for a means to cool the head of a wearer by incorporating in a flexible tube, a liquid adsorbent material which provides for evaporative cooling of the liquid and thus cooling of the head of the wearer. The adsorbent material can be easily re-saturated with liquid by simply immersing the whole invention under the liquid or under a flow of the liquid. The device is easy to manufacture and simple to maintain.
