Physiological strain during exercise-heat stress experienced by soldiers wearing candidate chemical protective fabric systems. Technical report

The heat-stress problem of soldiers working in warm environments wearing chemical protective clothing is well documented. The thermal insulation and low moisture permeability of such clothing severely limit the effectiveness of the body's heat dissipating mechanisms. Several foreign and domestic experimental fabric systems are now available, and the thermal and vapor transfer characteristics of some of these systems have been tested in static configurations. This technical report describes the evaluation of three experimental fabric systems for their effect on thermal strain experienced by soldiers during exercise in the heat.
