I guess I've gotten to feel so secure with the wraparound effect of the Ol' Man that I don't wear one much. I would definitely wear one if I used an "open-front" climber. I do in my fixed stands. I'm an idiot whose false sense of security will probably come back to bite me. It just seems nearly impossible for a fall with the wraparound. Only thing that could happen was the cable breaking. I need to buy the seat of the pants type harness. the others are a real pain.
