Abstract
A head or wrist sweatband including united sheet sublayers of foraminous heat conductive foraminous and moisture absorbant fabrics, for immersion in tap water at room temperature, functioning to evaporate the water with concurrent cooling of the human body and absorption of perspiration. The inner surface of the band is comprised of said heat conductive foraminous fabric first sublayer and in use is adjacent the skin of the wearer. Said moisture absorbant second sublayer is connected in interfacial association upon said first sublayer and forms the outer surface of said band. In use, the band is initially immersed in room temperature water and placed upon the user. Heat from the body of the user raises the temperature of the first sublayer which in turn raises the temperature of the second sublayer causing evaporation and consequent cooling of the band. Perspiration from the user is absorbed by the second sublayer for continous evaporation and cooling.
