Bedwetting Underwear

Soft & Cozy

Kids love these soft, fluffy undies. They feel amazing and give kiddos confidence when they wake up dry

Bedwetting Pants used as Big Kid Diapers


Getting out of plastic disposable baby diapers can do wonders for a child's self esteem.  Put on some comfier thoughts :)

Waterproof big kid diapers


I can remember so many mornings where my son would wake up in a sad, soggy puddle. Not anymore, baby! Waterproof gussets lock wetness in!

Save SOOOO Much Money - Who Knows How Long Bedwetting Will Last!?!?

Most families spend well over $600 on disposable bedwetting products per year. That's the price of a weekend vacation! Super Undies can last 3 or more years, saving you money, and saving the planet :)

Big Kid Diapers

Strong Waterproofing

Super Undies are made with PUL, which is a thinly laminated non-wicking fabric. PUL has a soft drapey feel to it, is waterproof in nature, but allows more breathability than disposable diapers. Waterproof gussets line the legs of these Undies, locking in the wetness.

Adjustable Absorbency

Underwear for night time potty training and bedwetting should be very absorbent and accommodate whatever your child can put out without leaking, but still allow the child to feel wet. This helps create the brain/body connection necessary to work through nighttime potty training, and that's exactly what our Chameleon Undies do!

Chameleon Undies 3-Pack


Chameleon Undies are a direct replacement for UnderJams or GoodNites. They are very waterproof, and have absorbency that allows you to adjust to your child's needs. Whether your bedwetter is a leaky faucet or a fire hose, the Chameleon can adapt for a good night's rest!

This set gives you three pairs of eco-friendly reusable bedwetting underwear (1 Lava, and 2 Frozen), and a washable Wetbag to to store your pre-laundered Undies in. That's enough Undies for 3 nights. Just throw the wet undies in the Wetbag until it's time to wash. Your Wetbag can simply hang on a doorknob and collect undies as they are used, and can hold between 3 and 6 pairs.  It is waterproof, washable and reusable. Our Undies can typically last a child through 2-3 years of growth, and can last up to 6 years of wear and tear. This means you can use them through multiple kids, or sell/donate them when your done :)

You may still be wondering if these will work for you, and we want to be very transparent about that. Chameleon Undies work for boys and girls. Our unique insert system is the bomb. It's our secret sauce to success! Use 1 for a trim fit and a light wetter. Use 2 inserts to hold back the hoover dam!

Chameleon Undies also have a build in size adjustment in the waistband to help you get a good fit and let these undies last longer. Just fold down the waistband to cinch up the rise!

While the initial cost of cloth may seem pricey at first, when you truly compare the cost you’ll find in the long run Super Undies can save you a lot of money! You can get them cheaper by purchasing them as a package deal. 

Studies show that as your child gets older it is important to embrace this area with workable and practical solutions. Kids need to know that they are being seen, heard and cared for. Ignoring bedwetting all together and quietly providing a disposable larger baby diaper can have lasting effects on a child’s self esteem. The truth is one in every four kids in a first grade classroom are still wetting the bed! By the time boys are 7, one in ten are still wetting the bed. This problem is bigger than you thought. Your kid is completely normal!

Here’s the kicker - It’s not even a problem. Trying everything under the sun to eliminate bedwetting shows kids that this IS a problem to fix, and causes them to feel powerless and broken.

A kids starts to think... what’s wrong with them? Why do they do this? The best way you can help your kiddo is to normalize it. Remove the baby diaper stigma by taking away the disposables. Give these kiddos their dignity back by providing them with a reusable cloth padded underwear that contains the wetness and just gets tossed in the laundry. A pair of super undies can last up to 3 years in size, but 6 years of regular use!  That means that by supplying your kiddo with 6 pairs of undies they will have a healthy rotation, colorful fun options to choose from every night, and no pressure to NOT wet anymore. Once you have Super Undies, no more money needs to be spent and no extra laundry is generated. Just throw your undies in with the load of towels you are already washing.

And here’s the best part - 15% of kids that switch from disposables to cloth show reduced bed wetting within the first 2 weeks of use, and THAT makes your kiddo feel MUCH better!

Chameleon Undies are a direct replacement for UnderJams or GoodNites. They are an all-in-one heavily padded, waterproof underwear developed for children to use overnight when they wet the bed or are night training.

All Hero Undies


Kids peeing the bed is a normal part of life. You can see bedwetting in children drop as a child gets older, but there is no way to tell when a child will stop peeing the bed. Hero Undies are DOUBLE waterproof, featuring all around gussets and 5 layers of absorbency. That’s well over your average cloth diaper or disposable diaper capacity. Hero Undies offer flexibility like no other. Our flexible absorbency system can convert the undies from daytime to nighttime and back again, simply by adding or removing the step-up insert. Their internal construction is brilliant!

  • 100% Waterproof design
  • Internal waterproof gussets at legs and waist offer 360°  extra waterproof protection
  • Standard boxer/brief style waistband for discretion, even if they peak out.
  • Thick 5 layer flexible absorbency system can be snapped in and out for quick replacement without changing the briefs. Insert system can be used with one insert, or the included two inserts joined together;
  • Bigger sizes for older bedwetting children

Although cloth may seem expensive at first, when you really look at the cost it's not! You can even make cloth cheaper when you buy a 3 pack. Your kiddo can feel better about bedwetting if you take away the disposable baby-like diaper and give him a practical solution that looks more like real underwear.

Hero Undies will empower your child to own their situation by giving them full control over bedwetting, no longer relying on you to buy them expensive diapers, and you can rest easy knowing you’ve done your part to help the environment.

If you're wondering if these will really work for you, consider this before you buy them :) Super Undies offers two style of bedwetting underwear. Make an informed decision by checking out what the difference between each is.
