This vintage uniform pants have a rear tag marked 29X31. The inside pocket tag is marked TROUSER'S MEN'S COTTON U.T. 8.2 OZ. KHAKI, Shade 1 Type 1, Class 1 DSA-100-4137. The DSA number does not have the year code number while clothes after the Vietnam Era have a Polyester Cotton mix. They have 2 front and 2 rear pockets, good front metal zipper and buttons. There are 7 belt loops. The Soldier's number W-8527 is stamped in several places. I measured them at 28 inch waist and 29 inches on the inseam plus a 2 inch hem. They are used with wear in very good condition.
