Abstract : The Navy Clothing and Textile Research Facility (NCTRF) physiologically evaluated the Navy's cold-weather clothing by exposing subjects wearing either the Al (Extreme-Cold-Weather) clothing ensemble or the A2 (Buoyant, Intermediate Cold-Weather) clothing ensemble to various environmental temperatures. The environmental temperatures in which the clothing was tested included: 5 deg F (-15 deg C), -10 deg F (-23.3 deg C), -30 deg F (-34.4 deg C), and -40 deg F (-40 deg C) for evaluation of the Al ensemble; and 39 deg F ( 3.9 deg C), 20 deg F (-6.7 deg C), 0 deg F (-17.8 deg C) and -10 deg F (-23.3 deg C) for evaluation of the A2 ensemble. An additional exposure to -40 deg F was undertaken to compare responses with the Army Arctic gear, and an exposure to 70 deg F (21.1 deg C) while standard Navy utility clothing was worn served as a control. Exposures were 3 hours in duration, the first hour of which the subject sat quietly, followed by 1 hour of exercise at 3.5 mph, and again 1 hour of rest. Based on mean skin temperature responses, the results indicate that none of the test garments would keep an inactive person warm for prolonged periods of time (4.O hours).
