Abstract
A new Canadian Forces parka (74 Pattern, NSN 8415-21-870-5571) was compared to two other parkas (51 Pattern, NSN 8415-21-103-8127) and 71 Pattern NSN 8415-21-859-6306) in a test in which a quantitative determination was made of their thermal insulation characteristics. Six Canadian soldiers were used as subjects in the test in which measurements were made of rectal and skin temperatures during each subject exposure as well as the temperatures on the interior and exterior layers of the parkas. It was found that the 74 parka was the warmest of the three types while the subjects were standing at rest or walking. However, the increase of energy expenditure during the act of walking was greater in the case of the 74 parka because of its longer length. Furthermore, the heat associated with this energy expenditure was not eliminated as readily as in the 51 parka. It is therefore suggested that the 74 parka be modified by decreasing its length.
