Abstract

Abstract A head gear for supplying water to evaporatively cool the forehead and upper head of the wearer. The head gear includes a main band which extends over the top of the head from ear to ear and a forehead band which extends over the forehead and is stitched at each end to the main band at about the temple areas of the head. A pair of water-tight containers is secured at the ends of the main band near the ears. The bands are of absorbent material and the main band extends inside the containers and is immersed in water. An elastic band is joined to the main band to extend over the back of the wearer''s head, firmly supporting the head gear in place. Water is supplied continually to the band upon the wearer''s forehead and upper head by the hygroscopic action of the absorbent material and the evaporation of the moisture in those areas creates a cooling effect.
