There is no sensible way to make a reversible airbag harness look good on the ground. This FIREBIRD MOWENPIK REVERSIBLE PARAGLIDING HARNESS, however, is a gem of excellence.
I flew them for as long as they were in production, and they remain the best harnesses I even owned. This one belonged to me for a while, so will be a good fit for somebody 5'9" to about 6'. It has a couple of small nick in non-critical areas, but thos is easily repairable, and is otherwise excellent throughout.
