The author has mentioned in the second report of this series about the seasonal variation of the pieces of garments and the sensation of thermal condition of the environment. Present paper deals with the measurements of the seasonal variation of the weight and the thickness of garments in working conditions both outdoor and indoor. Also the relationship between the measured values and the thermal feelings was examined. The following results were obtained. At the temperature of 20°C which is most comfortable for human body, the average weight and pieces of garments for out door farm work were 2116.9 g and 11, 0 pieces, respectively, and those for outdoor regular garments were 1089.9 g and 7.6 pieces. As for the indoor garments, 1128.0 g and 4.5 pieces for working clothes and 1148.7 g and 8.1 pieces for regular clothes, respectively, were the average values. Wearing standards for thermal environment in the four seasons of Akita area of north-eastern Japan were established from the regression lines between the temperature and weight of garments for farm working and regular clothes, outdoor as well as indoor. Observed values of the garments which measured in the females who stated "comfortable" fell weithin the ranges of the above mentioned wearing standards.
