Abstract
Upper and lower body cold weather garments are provided which have excellent warmth, moisture permeability, wind resistance, and water resistance. The garment comprises an interior lining fabric, such as a loosely knit nylon lining, an outer fabric, and a layer of preponderantly open cell (e.g. polyurethane) foam at least 1/2 inch thick (preferably about one inch thick) between the interior lining fabric and the outer fabric, the components connected together by stitching at the edges of the garment. The outer fabric has air permeability of less than 15, and preferably less than 10, cubic feet per minute per square foot at 0.5 inches head of water, and has moisture vapor transmission of at least 1,000 grams per square meter per 24 hours. The outer or shell fabric preferably is woven from a fine denier, multi-filament, polyester yarn. The upper and lower body garments, when worn as the only cold weather protecting garments and without any other garments having poor moisture vapor transmission, provide extremely effective cold weather comfort even in windy environments.
