I have on red one in stock. 2 inch and I would call the stiffness medium, scooter ring and loop are sewn in and it has a black neoprene pad. Came from a HOG red harness kit. I used the main webbing for another project that ended up cutting to pieces in a rescue class.well that went sideways fast!
Piranha may be a good viable option. I know they have regular and stiff webbing but i haven't seen any soft.
I'll make you a good deal on it.
