Abstract : This study is conducted in order to validate under outdoor conditions, and if necessary, to adjust the mathematical models, which were developed in USARIEM, to predict physiological tolerance under different environmental conditions, solar loads, clothing ensembles, and metabolic rates. Different physiological parameters were carefully monitored. The results show that the prediction models, which were developed from laboratory studies, are conservative and overestimate the physiological responses under outdoor conditions. It is hypothesized that a factor related to long waves radiations should be included in the equations. This issues will be investigated during the next phase of the study. Keywords: heat stress; clothing; heat exchange; environmental extremes.
