Reproduction of the standard issue trouser for all Army (including Air Corps) personnel throughout WWII. These pants were worn both in the field and with the Service Coats or Ike Jackets. ATF's reproductions are made from wool serge cloth custom woven in the correct WWII olive drab shade. (It looks like an olive brown). The cut and pattern were copied from original trousers. The sizing is equivalent to all casual modern trouser sizes. If you wear a 36 in jeans, this 36 will fit. All inseams are 34 inches (86cm). Other Cleaning Options:1. Hand wash in the sink or a bucket and air dry- as in the open air, on a clothes line. Not in a dryer!2. I have had good luck with the "hand washables" setting on the new high efficiency washing machines. This is NOT equivalent to the "gentle" cycle on older machines. Air dry, as above- not in a dryer but outside in the air you breathe.
