I cut rubber bands from my old bike tubes, usually the 28mm-32mm size from my Cross-Check, and slide them onto the webbing for various purposes. If the rubber band causes the webbing to crush/bow, then in my opinion it is too soft. Several of my harnesses bow and I hate that, the keepers (and I call them keepers) slide, the shoulder straps sag making them hard to get into and all in all I like the stuff that is relatively stiff enough to hold shape. The Oxy webbing seems about right.
