There are cases where there are delicate color shade differences for each part as one of the features often seen on the Battle Uniforms in Viet Nam era. It is supposed that it happened because many clothing makers had a huge amount of government orders in the short terms during Viet Nam War and the allowable range of color difference in battle garments was generous. This time MASH reproduced the "Mixed Shade (subtle color tone difference per part) Model" which is sometimes seen in the original US OG 107 Sateen Trousers using the original GI fabrics which are subtle color tone differences. In order to understand the delicate color difference of each part below, we will introduce 6 cases (Ex.). However, these are reference examples among many variations. Please refer to the page of the "US OG 107 Sateen Trousers, 1st Model" for the details of each part and comparison with the original and our reproduced trousers. Thanks.
