The subject is equipped with numerous temperature and humidity sensors on the skin and judges his subjective thermal and moisture sensatiion as well as the resulting overall comfort in distinct time periods and varying conditions.
The subjective perceptions of the wearer and the measured temperature and moisture data are compared and subsequently correlated with the data from the skin model and thermal manikin. This fully validates the wearing trial.Hohenstein says the overall comfort of combat uniforms for cold environments is not only due to the thermal insulation characteristics of the garments but also influenced strongly by the water vapour #
Combat uniforms for cold environments can be designed for specific climatic conditions and physical activity using existing test procedures and standards. Not only the thermal insulation but also the water vapour resistance of the whole garment is of importance.
A low water vapour resistance ensures sweat evaporation and results in a dry insulation layer and thus less heat loss. The hereby improved overall comfort ensures the mental and physical performance of the soldier under cold environments.
