First Claim
1. A cold weather garment comprising:
- an interior synthetic lining fabric;
an outer fabric;
of layer o preponderantly open cell foam at least 1/2 between the interior lining fabric and the outer fabric; and
the lining, foam layer, and outer fabric connected together by connecting means to form a synthetic garment; and
wherein;
the outer fabric comprises a fabric having an air permeability of less than 15 cubic feet per minute per square foot at 0.5 inches head of water, and having a moisture vapor transmission of at least 1,000 grams per square meter per 24 hours.

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.

20. A method of protecting a living human being from cold, comprising the steps of:
-
constructing an upper body garment for covering the human'"'"'s upper body and arms, the upper body garment having arm portions, and the garment constructed by disposing a layer of preponderantly open cell foam at least 1/2 inch thick between an interior lining fabric and an outer fabric having an air permeability of less than 10 cubic feet per minute per square foot at 0.5 inches head of water, and having a moisture vapor transmission at least 1,000 grams per square meter per 24 hours, by stitching around the edges of the garment to hold the foam, lining, and outer fabric together at the garment edges; constructing a lower body garment, having leg portions, in the same manner as the construction of the upper body garment; and providing the human with the upper body garment and the lower body garment covering the human'"'"'s body, arms, and legs, so that the upper body garment and lower body garment are the only cold weather garments protecting the human'"'"'s body, arms, and legs, and so that the human has no garment on the body, arms, or legs that has poor moisture vapor transmission. - View Dependent Claims (21, 22, 23)
