I digressed a little:
A DIR Style backup regulator replaces the typical Octopus with a second 2nd stage reg. secured around your neck with a bungy cord (aka necklace). Your regular second stage has a hose of either '5 or 7' that is routed under your right arm, up across your chest passing over your left shoulder, around the back side of your head, finally reaching your mouth.
A picture is worth a thousands words, eh?
You might be able to make it out here:
