Military Issue Base Layer Lightweight polypropylene Long Underwear Bottoms Medium

Size Medium 31-35 inches The LWCWUS is a thin, quick drying, hydrophobic, moisture wicking synthetic garment set composed of long underdrawers and zippered neck long undershirt (not included). It is launderable using standard commercial equipment. The current cold weather underwear provides excellent insulation in extreme cold weather, but is too warm in moderate cold conditions. Marines conducting strenuous activity would perspire heavily causing the underwear to lose its insulative qualities. The result was Marines suffering from hypothermia, dehydration and other cold weather injuries. The LWCWUS does not have the deficiencies of its predecessor. Extended Cold Weather Clothing System - Generation II Lightweight Cold Weather Underwear Set (LWCWUS) was developed to provide a moisture wicking, heat retentive, lightweight garment for moderate cold conditions in which the polypropylene garment is too warm.
