    We developed cooling clothing that utilizes water evaporation and can adjust the cooling intensity according to the user’s preference. The continuous cooling effect is supported by a small supply of clean water, and wet discomfort is prevented by using a textile with waterrepellent silicon coating on the inner surface. We conducted experiments with human subjects in climate chambers maintained at 30 °C and RH 50% to compare the effectiveness of the cooling clothing with that of other convective cooling devices. The use of cooling clothing with a convective cooling device improved the subjects’ thermal comfort compared to convective cooling alone. The supply of a small amount of water allowed the cooling clothing to provide a continuous cooling effect, whereas the effect of convective cooling alone decreased as sweat dried. However, the controllability of the cooling clothing needs to be improved.
