In order to develop objective evaluation equation for comfortability of water-resistant and vapor-permeable fabrics, heat and water transport properties of the fabrics were measured and the relation between those properties and subjective values of clothing comfort was investigated. Relative humidity change within clothes was also studied during exercise with the clothes. Following conclusions were obtained. Clothes made of fabrics with larger degree of vapor-permeability were evaluated to be more comfortable. In three methods of vapor-permeability measurement, water method was shown to be better to evaluate clothing comfort.
　Clothing comfort could be roughly evaluated objectively using the data of fabric vapor-permeability by water method. If the increase of relative humidity within clothes was larger, the clothe was evaluated to be more uncomfortable. Clothing comfort could be estimated easily from the change of relative humidity within the clothes. Clothes made of fabrics with higher thermal insulation value were evaluated more uncomfortable in this experiment. Although the pulse rate increased by exercise, the relation with clothing comfort was small.
