Sweating thermal manikins represent the anatomical shape of the human body, and are used to assess heat exchange between the clothing microenvironment and surrounding ambient. In the field of textiles they are commonly used to evaluate the thermal and evaporative resistances of clothing ensembles, while in the automotive and construction industries they are used for the evaluation of the efficiency of environmental control systems for vehicles, living and working environments. The present study reports the use of a whole body thermal manikin in the process of optimization of existing combat ensembles of the Slovene Armed Forces. Results obtained during field trials conducted with human subjects are compared to results obtained with a thermal manikin.

Triad person-clothing-environments set specific requirements in the development and optimization of products in the field of personal protective equipment that integrates into the transportation, living and working environments. The optimal balance in the triad as well the effectiveness of its relationship depends on the clothing, environments to which workers are exposed while performing their activities and on their performance. The aim of the present study was to determine the optimal combat clothing ensembles conducting hikes and guard duty during winter and summer months. During the trials, the subjects were instrumented to obtain skin and core temperatures, clothing microenvironment temperatures and humidity, as well as oxygen uptake and heart rate. In addition to providing data regarding thermal and evaporative resistances, the manikins also provided data for a numerical model of human temperature regulation, which was used to simulate the field trials. According to the given facts the relationship discussed in the paper is man-clothing-environment triad in terms of thermal comfort, requirements for the simulation of thermoregulation and the use of heat manikin.

Thermal factors are often important in determining whether a given clothing ensemble is suitable for use under specified conditions. Although final approval of a particular ensemble often involves field trials, the need for such trials can be minimized by measuring the thermal properties of the garment using a heated manikin and then predicting human behavior using a mathematical human thermal model. While many laboratories are capable of measuring the properties of garments using manikins and several mathematical models exist, there have been very few published comparisons of actual human behavior with model predictions. Agreement between predicted and actual behavior was reasonable, although there were significant differences which could be attributed both to deficiencies in the model and to difficulties inherent in conducting field trials of this kind.
