The Sladen Suit was a heavy type of British divers' drysuit made by Siebe Gorman. It is entered by a wide rubber tube at the umbilicus: this tube is folded and tied off before the diver dives. It was used by British manned torpedo riders and for general underwater work. Its first make had two small eyeholes. It was redesigned with the big oval flip-up so the wearer could get binoculars to his eyes.
"Universal" rebreather
There was an oxygen rebreather called the "Universal" that was designed to be used with it. The Universal was a long-dive derivative of the Davis Submerged Escape Apparatus.
