Abstract
DCIEM field-tested three prototype ski clothing ensembles for thermal and vapour transfer characteristics. Each ensemble differed in their combinations of insulation and shell fabrics, which would affect their capacity to retain and transfer water vapour to the environment. Three male subjects were used to test three conditions. Each condition required a chairlift ascent before skiing in sequence each of 14 pre-set, intermediate to expert descents at a western Canadian ski resort. Subjects experienced 268.0 minutes (+/-7.0 minutes) exposure of which 85.3 minutes (+/-4.7 minutes) were active skiing. Subject's activity levels averaged 3.7 times greater than rest. No ensemble provided effective confort since all toe temperatures were 3 degrees below 15C. Lower body garments provided less protection than the upper body. Subjects perceived wind permeability as an important confort factor. During rest, garment compression and increased conductivity was observed which caused subject's legs and back to lose a larger amount of heat to the previously weather-exposed chairlift seat. When activity changed from rest to skiing the areas that experienced greatest heat flux and skin temperature changes were hamstring, abdomen and chest. Skiing activity and its resultant air flow increased heat flux for subjects anterior torso and legs. Sweat accumulation was never a concern in this trial. TRUNCATED
