This diapers and pads for heavy incontinence section and the Overnight Section are for if you leak more than eight ounces of fluid. Choose between reusable or disposable. If you're extremely incontinent, be sure and switch over to the Overnight Section.
There's even some pads in the pads and liners area that are big enough to absorb over eight ounces of fluid per wear. There's a lot of reusable products at this level too. Try the Super Fitted Reusable Briefs with Snaps.
