ABSTRACT:
A cold weather system for keeping a wearer comfortable in a temperature of about -60.degree. F.-+40.degree. F. and winds up to 100 miles per hour; utilizes a shirt, pants, parka and wind shirt and wind pants. A sleeping bag and moisture handling pad/deicing cloth are compressed in compressor bags and easily transported by the wearer for comfort during sleeping too, and used with a bivvy sack having a tent flap. The shirt and pants are ventable so that they provide comfort over a wide temperature range, the vents being completely closed when maximum thermal protection is desired. The parka includes a windskirt which engages the wearer's legs. The wind garments are made of fine denier 100% synthetic material tightly woven so that they have very low air porosity. The parka and wind shirt can be connected together to provide an emergency bivac sleeping bag. The skirt, pants, and parka include an inner fabric of 100% synthetic material, an inner layer of foam at least 1/8 inch thick, and up to about one inch thick, and an outer shell of low porosity, but high moisture vapor transmission, material. Portions of the shirt and pants that will be vented also include a fabric covering the insulation, the insulation covering fabric having very high air porosity.
