Abstract: An inner garment for aiding evaporative cooling includes a first sheet containing a substantial portion of cotton. One face of the first sheet is worn next to the skin where it acts as a wick for perspiration. A second sheet in the form of a resilient, wrinkled, porous web is disposed against the other face of the first sheet to form an evaporative cooling space when an outer garment is worn over the inner garment. Preferably, a perforated third sheet of woven thermopolastic fibers is disposed over the outer face of the wrinkled web to protect the web and restrict loss of moisture primarily to the evaporative process.
