The OMS website is displaying a wing that they are marketing as beings specifically designed for rebreathers. They call it the Tesseract Rebreather BC. I currently use a Dive Rite Nomad System on my Optima, but I previously always used OMS harnesses and wings when I did my open circuit deep diving. I never had any complaints about the OMS gear I used. I went with the Nomad system, because it has a soft backplate and the wing and backplate are connected together as one item. However, the added bottom buoyancy and dual widely spread dump and bc hose inflator on the OMS seem interesting. I wonder if it has a back/rear dump for when you are diving in the horizontal position? Here's the link to the OMS site that has a picture and discription of the Tessetact (
