Polypro long underwear shirts are part of the military ECWCS system. This is the base layer that goes under the fleece liner (bear shirt), with a Gore-Tex jacket over the fleece liner.

These shirts are very warm and wick away moisture from the body better than most fabrics! They are available in brown only and turtle neck with zipper only. These shirts are new and unused.

Please, hang dry this item, heated dryers will shrink them.
