PaxBoy, given your diversion, how about belts?
A problem with cargo pants is they tend to be weighted down and hence need a belt.
But security tells you to remove belts. Why?
Is it the metal buckle? Is it the potential of the belt as a weapon?
My cargoes would therefore have a sewn in belt that could only be removed with the trousers attached. At a stroke this would overcome th eproblem of having to empty ones pockets of metal. Simply strip your pants off and put them in the scanner.
And what of braces?
