Lightweight Cold Weather Underwear Set

Lightweight Cold Weather Underwear Set (LWCWUS) was developed to provide a moisture wicking, heat retentive, lightweight garment for moderate conditions not sufficiently cold for the polypropylene underwear.

Description of Item

The undershirt has long sleeves with elastic wrist cuffs. The wrist cuffs consist of double thickness of the basic fabric. The wrist cuffs have sufficient elasticity to prevent constriction of blood flow to the hands. The undershirt has a zipper that begins in the center of the collar top and extends to a level near the bottom of the user's chest. The zipper is designed for easy operation with a gloved hand, and provides the user with ventilation during strenuous activity and is a good match to the basic shade.

The drawers extend from the user's waist to a level below his/her ankles and end with elastic ankle cuffs. The ankle cuffs consist of double thickness of the basic material. The ankle cuffs have sufficient elasticity to prevent constriction of the blood flow to the feet. The waist band is made of an elastic hydrophobic, synthetic material. The drawers have a standard fly hole in the front.

Materials Used

The undershirt and the drawers are composed of 100 percent polyester material which weighs no less than 4.2 ounces per square yard and no more than 5.5 ounces per square yard.
