To get the basic data for making comfortable military uniforms and to examine the distribution of clothing microclimate, seasonal fluctuations of skin temperature, subjective sensation, and clothing microclimate were measured from 10 males. The subject were questioned on thermal comfort in experiment. Clothing microclimate temperature at breast, skin temperature at four sites (breast, upper arm, thigh, leg), deep body temperature at eardrum( tympanic temperature), and subjective sensation were measured for an hour in the controlled climatic chamber. The subjects felt comfortable when skin temperature were recorded $34.43^{circ}C$ at breast, $33.53^{circ}C$ at upper arm, $32.9^{circ}C$ at thigh, and 32.50 at leg. Then mean skin temperature was $33.55pm$$0.63^{circ}C$. Clothing microclimate temperature ranged from 31.2 to $33.8^{circ}C$, and clothing microclimate humidity ranged from 49.80～52.41%. In the comparison of these results with the microclimate of military uniforms, it needs more insulation in clothing for military uniforms. It also says that military uniforms should be made of the textiles which can control humidity.
