I think you mean the tank "bra", yep I've got one. I bought it used from another BA.com member. I like the look of it and I think it does help protect the tank from scratches from my jacket zipper. I like the velcro pouch as well, handy spot for money when I fill the tank.
I noticed, in the past, that some people feel dirt and dust will accumulate underneath the leather, but that's not been a problem with mine. It doesn't lay perfectly flat, but I'm ok with that. It's not intended to be a show bike.
This is a pic before I re-installed the Bubs, mounted the tank pads, Nology coils/wires, engine bar and un-lowered her.
I like it, but that's just me.
