Thermal Comfort Performance of Tactical Vests with Different Cushion Lining

For thermal comfort assessment of three different cushion-lined tactical vests, sweating thermal manikin were employed to test the thermal resistance and evaporative resistance of the tactical vests, and the Heat Strain Decision Aid (HSDA) model was used to predict the core body temperatures and maximum working times at various work intensities in warm and humid as well as hot and dry conditions. The results indicated that the tactical vest with a polymer sponge cushion strip was more adaptable to warm and humid environments, the tactical vest with EVA compression film cushioned was more suitable for hot and dry environments, and the tactical vest with a strip fabric cushion layer had the longest maximum working time under all intensities and environments, proving to be the most adaptable to various conditions.
