Comparison of Cold Weather Clothing Biophysical Properties: US Army, Canadian Department of National Defence, and Norwegian Military

Abstract

This report provides quantitative biophysical assessments of current cold weather clothing ensembles used by the US Army, the Canadian Department of National Defence, and the Norwegian military. Standard tests for the thermal and evaporative resistances (Rt and Ret) were conducted for 22 military cold weather ensembles (9 United States (US), 8 Canadian (CA), and 5 Norwegian (N)) within climate controlled environmental chambers. Total thermal resistance (insulation) in clo units, the vapor permeability index (im), and the evaporative potential (im/clo) were calculated from Rt and Ret measurements. Simple comparisons of the measured values for each of the ensembles was made as well as predicted performances based on modeling of insulation required to maintain safe exposure times.
