Historic for the early artificial fabric as well as the military aspect, and you might just want them to wear.There are some light black dirt smudges on the bottoms of the legs which should wash off and if it does not I will issue a credit or adjust. If I wash them I am going to charge you more to begin with and I don't like to machine wash old garments as the detergents can add UV enhancers. Very small moth nip near a pocket can be sewn over in a moment. Absolute bargain price for this garment. USA only for these and shipping is folded into a Flat Rate Priority Envelope, they won't get hurt and it costs the least.
