I got to thinking, who invented cargo pants? I know I saw them on boys’ fasnions for years, and thought maybe they were an urban sort of design. Then I thought, didn’t the US Army wear them? I looked on Wikipedia and they originated with the British Armed Forced (1938!) and were called “battle dress”. The pockets were intended for bandages and maps. They were in the USA by the mid-40’s. Our US Paratroopers used the pockets to hold extra K-rations and ammo. Nowadays, in urban settings, they can be used to take some extra food with you instead of having to carry it in a sack.
