*Rated values for moonyman Air Fit S Size. A comparison of up-the-back loose stool leaks in Unicharm tape-type diapers. According to research by Unicharm.

Up-the-back diaper blowouts tend to happen... when being held or in a sitting position

In a baby stroller

When being held (or during breast feeding)

When lying down

No worries about diaper blowouts even when the baby is in positions like these, which tend to bring about up-the-back diaper leaks

Whether you're on your way out or are breastfeeding, babies don't think about mom's inconvenience when they poop…

We designed the 3D loose stool pocket to help such mothers out!

Disposing diapers is also made easy and leak-free with the roll-up tape

No leaking from the side or odors! 
Folding into compact size also allows easier disposal!

Hooked fastener ensures the used diaper stays compactly folded after disposal and doesn't take up space in the garbage pail.

Diaper features

Of course, it is full of all features that are needed for diaper.

"Soft and perfectly snug gathers" that fit gently but snugly

Made to match to your baby's ability to reach their feet. Made with Soft Stretch material instead of elastic on the sides where the diaper is in contact with your baby's moving legs!

"Air silky material" that's gentle on the skin

Air silky material, with fibers as fine as silk, is used in the inner sheet that comes into direct contact with the baby's skin. The diapers are now even gentler on the skin

What's more,helps keep loose stool from spreading inside the diaper!

The original undulating structure helps keep loose stool from spreading and prevents leaks.

"Back-leak prevention sheet" that keeps seepage at bay

A back-leak prevention sheet has been adopted for loose baby stool.

It even prevents seepage on the back.

"Super Slim" absorbent core

Absorb up to 12 hours.

※The amount of urine differs from baby to baby. This is a rough indication of the amount of urine the diaper can absorb, not an indication of the length of time diaper can be used.

”Full ventilation sheet"

Even the babies with high body temperature and tends to be sweating a lot, this diaper can keep their bottom dry.

"Notice sign"

The notice line changes to blue-green when your baby pees, so it's easy to know when to change the diaper

Comments from moms who've used this product

I tried it for the first time when I was exhausted from having to wash soiled clothes and towels every day because of leaks and diaper blowouts that happened every time my baby pooped. I had to do this while trying to stop my baby from crying. This diaper does a great job of preventing up-the-back diaper leaks, so I no longer had to worry when placing my baby on a bouncer, when leaks tended to happen, or when going out. It's resulted in an amazing reduction of stress related to stool leakage!
Riho's Mama
When using a tape-type diaper, I was always worried that stool might leak up the back even if it fitted snugly around the waist. So, I was always in a mad rush to change a diaper. On the other hand, pants-type diapers fit very snugly. They also have a pocket-like thing on them. I don't worry about leaks anymore. Just like tape-type diapers, they can be folded up compactly after use, which I find very helpful.

It folds back on the inside in the back, so I was able to use it without worrying about leaks even with loose stool. What's more, it fit snugly but left almost no elastic marks on the tummy, back and legs. It looked comfortable for my baby to wear.
After use, I could fold it compactly using the tapes on both sides, which was great when I'm out. (It was the first time for me to see a pants-type diaper with sticky tapes on both sides.)

My baby's started moving around a lot recently, so I changed to pants-type diapers.
Things went very smoothly! I was worried that it might leak, but there's been absolutely none, so I'm glad!
YU&AYA-san

Every time there was a leak, I had to do lots of washing of towels and mattress pads, and sometimes I would get irritated when I was so busy caring for my child... I was so surprised that using this diaper, even with a large amount of stools, they stay in the diaper pocket properly!!
Thanks to this, there are no more leaks and now I can smile and interact with my baby while changing diapers!
