I received my used harness from Zev and it fits me well. It is quite comfortable as long as I wear it low on my hips and shorten the leg supports which are adjustable. It is safer than my bosun seat for sure. It is very compact to stow and light. I will have to keep an eye on the triangular screw link at the harness attach point, but I can attach my pulley rack directly to the link. I was playing with the harness and rack and had to leave to pick up my daughter and it was no problem to sit in the car and ride with it on, almost forgot it was on (except the safety yellow glow).
