Catnapper,
My husband has a nose piece called Comfort Classic. It fits over his nose & he has a harness that fits over the back of his head. The harness is attached on his forehead to a sponge type of material that is very soft & holds the top of the nose piece in place. The bottom strap attaches to the nose piece & can be adjusted. The head piece has velcro to make adjustments on the forehead & on the nose piece there are places where the strap goes through so it can be tightened to fit properly on both sides. I hope this is maybe helpful.
