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!

"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.

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.

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!
