As a male, a bigger consideration than full or half harness might be crotched (diaper) or crotchless design. I prefer crotchless, though a bit more hassle to get on/off. Women don't seem to care as much, one way or the other, lol.

OTOH, some hardcore offshore type guys wear a jock+cup (plus shin guards, helmets, etc.), in case they end up straddling a spar, so the diaper kind works fine and even adds more padding, "just in case".

Something to consider...
