[@Gunther] Personally, the closest thing I've used was [url=https://i.pinimg.com/originals/e2/e4/14/e2e41492bc53f61a20e80dc6a0c4d815.gif]the rescue-hitch of 1940's design from scouting[/url] (yes, it's still taught to this day)... fitted for a larger/smaller person because people were too lazy to re-adjust the knot for each person...

Which meant that rather than distributed evenly along 4 points like a STABO, it either crushed you nuts, squeezed your ribcage, janked your armpits, or chaffed your thighs... Oh, and you usually had the running-end of the rope literally in your face to the point strands of oily manilla were getting caught in your teeth.

Properly fitted, it wears quite a bit like a normal climbing/zipline harness (albeit the hitch itself is nearly fifteen pounds of rope with not much besides friction holding it up when not being lifted; and again, if the loops are too big, it's like wearing trousers fifteen sizes too big, filled with rocks).

If you can't tell, I hate this particular hitch with a burning passion, as it is needlessly complicated for what it does (3 non-slip loops, easily adjustable, from a single strand of rope) and there are a multitude of alternatives that have since been developed. Many of which I find quite a lot more comfortable and/or harder to make it so it doesn't fit.
[sup]For example, sitting in a single bowline loop is by far more comfortable than getting yanked by the ribcage alone with the thigh loops dangling loose by your ankles[/sup]
