Vietnam Experimental (?) Jungle Fatigue Trousers. Green poplin body. The buttons are small flat, rimless plastic buttons. The fly has a brass YKK zipper. Cut similar to an exposed button pair. Inside the waist is sewn a silk woven spec. type label. Also has the soldiers name written in ink. Have been worn and have never seen another pair like these before. There is some starch left in these, but we didn't want to wash them. Appear possibly Japanese made.
