Piss bottle and diver’s underwear

The hooker divers of old did not get wet. They wore large, waterproofed canvas and rubber suits, that filled with air as they descended to the sea bottom. Working for hours every day, in depths of up to 40 fathoms, they would get extremely cold. They wore layers of woollen undergarments to keep warm. As it took an hour to get dressed, divers stayed in their suits all day, and rather than undress, they used a bottle handed to them by their tender to relieve themselves during their short breaks.
