What the Cloth Nappy Doctor Says

The innovative Hero hemp/bamboo or microfibre insert is designed to give you a customizable option when fitting your child’s wetness capacity with absorbency. This is a two-piece set, consisting of a three-layer pocketed insert, and a two-layer microfiber Step-Up Insert pre-stuffed inside. It is the ultimate in overnight protection and offers you the best of all fibers.

The fibers of the hemp/bamboo offer you a long lasting tight hold to the wetness, while the microfiber gives you the fastest absorbency of any cloth insert. Together, this insert combination gives you the best of the qualities that modern day absorbency fibers can offer. You will need to wash the hemp/cotton insert 6-10 times for it to shrink down, fit in your undies, and be optimally absorbent.


If your child still wets through this insert, use additional absorbency to match their output capacity. The size and shape of this diaper insert is perfectly matched to the Nighttime Underwear Hero, offering full coverage from the top of the front of the undies to the top of the back of the undies. The flared-out contoured shape gives even more soaking power to the insert and helps it lock in place.Most parents start with the microfibre insert, but find if their child needs additional absorbency they add a hemp/cotton insert to assist in holding the liquid from the top microfibre layers. If additional absorbency is required at the front, back or groin of the Hero Pants, we suggest a one size booster in microfibre or cotton for added effectiveness. 


Commonly Asked Questions

Do I need to buy this insert separately from the Hero, or does one come with it?

All Hero Undies sold at Apikali come with a microfibre insert and Step Up boostser. Purchasing additional inserts allows you to easily add boosting when needed or to replace the insert while waiting for the other to dry. 

Why does the big insert have a number for the size and the small insert have a letter?

Super Undies has had a product called the Step-up Insert available for many years. It is a two-layer microfiber or cotton insert designed to help boost absorbency, so a parent can add more stuffing if the kid is a heavy bed wetter. When we developed the Hero Insert set, we decided to use the inserts already on the market so people can expand their sets as needed. Step-up Inserts are available to purchase separately, but one will come pre-stuffed in your Hero Insert Set. A Step-up Insert can not be used alone with the Hero Undies. It does not provide enough absorbency and should not be placed against the skin.

Which insert is the most absorbent, microfiber or hemp/cotton?

Microfiber absorbs faster, but bamboo/hemp will hold onto the wetness for a longer period, and will eventually hold more. This is why we include a microfiber insert in the core of our bamboo/hemp inserts. For a child who has a very strong fast stream, you will need the fastest soaking power out there. For a child who floods the bed, you will want bamboo/hemp.

What if this pull up pant insert does not absorb all my child can pee out in one night?

The magic formula for making any cloth overnight product work is to match or beat your child’s output capacity with absorbency. Most parents will find the insert that comes with the product is adequate absorbency for what they need, but some will have to seek additional absorbent options. For this reason, you can always get an additional Step-up Insert and add it behind the Hero Insert Set, or even a cotton washcloth! The cost of using disposables every night for years will seem like a weight off your shoulders if you just find that magic output/absorbency ratio for your undies.

Cloth Nappy Doctor Tip

Washing your Super Undies.


We always recommend washing our products in a garment bag. This will help prevent the inserts from getting caught around the agitator in your washing machine (if you have one) and getting torn or ripped away at the seam of the diaper.

We first recommend washing your Super Undies on either a warm, or cold wash prior to use once you have made sure the product fits your child. 

Once the product has been used we recommend using a diaper sprayer to rid the diaper of any solids into your toilet. 

If your Super Undies are soiled, use the diaper sprayer, or just shake the solids out into the toilet. To help reduce stains you will want to cold rinse and throw it into a open top bucket, or wet bag keeping it wet until you are ready to wash. You will want to wash our products every day or every other day. You will want to use your washing machines highest water level available. You may need to pre-rinse with no detergent and then follow through with a warm wash with detergent. You can then dry our products either in the dryer on low, or line dry them or a combination of both.

Please note that cotton is a natural fiber and does have a tendency to fray. Fraying of any cotton product is not considered a defect but rather something that can naturally occur.

You will want to avoid using chlorine bleach on a regular basis. It will start to break down the fibres and shorten the life and absorbency of the diapers. It also may irritate your child's skin. You also want to avoid using any fabric softeners, liquid or sheets. Fabric softeners coat the absorbent layers of the diapers and will reduce absorbency.

To lengthen the life of your Super Undies you will want to hang dry your diapers overnight, or partially dry in the dryer and then hang dry after a cold rinse. You can use 1/2 c. of lemon juice to whiten, or sun them in cold weather to freshen and remove stains.
