なぜ米軍チノにだけ“謎の内布”があるのか？

The turbulent 1940s were when the US military was producing "chino pants." It was a time when the government rewrote specifications every two years as the war progressed. This time, we'll delve into the "43 khaki," born right in the middle of that era. The single-stroke stitching of our previous model, the 191Z, was a matter of efficiency that naturally arose from the factory floor. Today's chinos are different. It's the government that's changing them. Therefore, we can clearly trace the reasons for the changes. What the three chinos, 41, 43, and 45, show: Changes in specifications: 1941: Simplified in preparation for war; 1943: Gas countermeasures implemented as combat became imminent; 1945: Reversed as the end of the war was in sight. The mystery of the fabric: The "gas flap" existed only on the 43 khaki. Preparations for a war that never happened remain in the fabric. Points of identification: The pocket lining of the welt pockets; traces of the time hidden on the inside. By the time you finish watching this video, you should see the record of a person who persevered, contained within "the one photo that disappeared in two years."
