To evaluate the effect of cooling garment and the local discomfort by wearing it, subjective experiments were conducted. The chamber was conditioned at operative temperature of 33.3℃, relative humidity of 37%, and still air. Proposed cooling garment has ice bags in it. To prevent condensation and to keep comfortable surface temperature, cooling packs were insulated with the four layers of aluminum, styrene, vinyl sheets, and water absorptive fabric. Inner surface temperatures of this cooling garment was about 16.8℃. Its cooling power at chest and back was measured by using thermal manikin and it was 33W/m². By wearing proposed cooling garment, skin temperature at chest and back decreased by about 3℃, while at foot it showed a tendency to increase (p<0.1). Thermal, comfort and sweat sensations were closer to neutral conditions by wearing cooling garment, and it made thermal acceptability better. On the other hand, it was found out that the difference of thermal sensation in the same body elicited the discomfort of local cooling. At design of cooling garment, it is important to take the distribution of local thermal sensation into consideration.
