In 1944, USMC (US Marine Corps) started using the P-44 pants, also known as the "Monkey Pants." They are the most well-known and distinctive trousers within the USMC. It significantly differs from the previous P-41 model with large cargo pockets on both the back and sides. The pockets on the sides were made large to fit k-ration boxes (military food rationing box), and the back pocket was to pack a camouflage poncho. With multiple pockets allowing a large amount of storage, reinforced holes were placed on the belt band to fit P-1941 suspenders to avoid the weight pulling marines trousers down.
