The article presents a physiological and hygienic evaluation of the heat-protective properties of winter clothing for outdoor activities taking into account criterial marks characterizing the human thermal state, using a measuring-calculating complex and special software. The software allows to calculate a thermal insulation value of clothing with the energy consumption, cold and wind, deformation characteristics of insulation, clothing package design, the air permeability of the upper fabric, the existence in the cold and the degree of human cooling. The use of computer technology at the design stage allows you to create clothes for outdoor activities of high quality with a stable heat-shielding properties, reduce development time and reduce the influence of the subjective factor of the designer. The carried out researches of the advanced design of a heat-shielding package confirm high quality and exploitative properties in real conditions.
