How absorbent are these compared to disposable adult diapers?
When put to the test, our X-large size diaper with inserts can hold 750 ml of fluid. That’s a whole wine bottle! But depending on size absorbency varies. Disposable adult diapers use something called SAP (Super Absorbent Polymer) to soak up the liquid on hold it, but that is not a sustainable practice. Not for the materials, and not for your wallet. While switching to cloth can certainly be scary at first, Super Undies has branched off a brand called Threaded Armor to be just that. Threaded armor. We have created the best leakproof system known in adult cloth diapering, and applied manufacturing techniques straight from our knowledge in modern cloth diapers. We looked and fit and function when crafting our products, rather than cutting corners, so you can rest assured that you will be getting the best adult cloth diaper on the market today. The absorbency in this product is directly related what you need. The unique system of adding inserts based on your needs makes them able to absorb what YOU need them to.

What size adult cloth diaper should I get?
We recommend you measure your waist rather than go by your pants size, then compare it to the chart under the SIZE TAB. Our measurements are actual fitting measurements. Choose a size that correlates to your measurement sitting right in the middle of the range we give.

How many diapers will I need?
Track how many diapers you typically use during the day and try to determine when you need heavier absorbency. You can always use our lighter absorbency, trimmer pull-on style adult diapers for a portion of the day and reserve the heavy absorbency overnight underwear for the times when you need more soaking power.

Commonly Asked Questions

How many of these would I need? We recommend two for a rotation, that way one item doesn't take al the wear from daily laundering. Anything item of clothing you buy will have a shorter life span the more it is laundered, so rotating your Nighttime Undies will keep them lasting longer. So will washing them in a garment bag, not using bleach, and not using fabric softener! Will my kid like these? I would like you to show your child the item before purchasing. Due to the sensitive nature of the product and the cost we incur by producing in American, we only offer exchanges for new items. Starting with gathering your child's opinion can be valuable in making sure he will wear them! Are these comfortable to sleep in? These bedwetting pants are super soft around the legs and waist, and great care was taken int eh pattern to make sure you get a smooth inner feel. We've never heard complaints of them being scratchy. The only complaint we sometimes hear is that the undies can be bulky. We are tasked with the job of using enough absorbency to match your child's output, and if we miss the mark and they leak, you'll be mad at us. We use enough absorbency to handle what most kids can pee out. Will they get hot? Heat comes from a waterproof barrier not being breathable, so air doesn't circulate. All a disposable diaper is really is a thin plastic trash bag with SAP in it. The ones that "cool" are covered in a chemical compound that creates a reaction (against your kids skin) when wet. Our bedwetting underwear doesn't count on plastic for it's waterproofing. We use PUL, a 1 mil breathable laminate on a non-wicking polyester fabric. That means our Nighttime Undies are cooler that the disposable competition. And better for the environment. And better for your kids skin. And made in American. And Super Undies in family owned. Doesn't that make your heart happy? What size would I need? Please refer to the sizing tab and measure your child. We use age recommendations as a guideline, but it is no replacement for measuring! And remember, The waistband of our bedwetting pants folds down to since up the waist and rise. This means you want to focus on your leg measurement and hopefully get it right in the middle of the given range.
