THE DESIGN OF EFFECTIVE CLOTHING FOR USE IN WINDY CONDITIONS

The traditional way of wind protection is to use wind‐proof fabrics as outer covers of clothing systems which resist moisture vapour transfer from the inner body, and this can cause associated discomfort. To solve this problem, three design methods are proposed in this paper. These are: (1) to cover the windward areas of the clothing systems with impermeable fabrics and the leeward areas with permeable fabrics; (2) to block the air movement within the insulating materials of the clothing systems, and (3) to have even air pressure distributions over the circumference of a clothing system. The practical value of these designs is evaluated by testing clothing assemblies on a cylindrical togmeter located in a wind tunnel.
