SERIOUS ISSUES with new Ninjamas!!!
Upon buying several boxes of these in hopes for something better from Pampers to compete with the GoodNites, these are by far WORSE than the Underjams!!! *Sizing is waaaaay too small for whats supposed to be a L/XL thats fits up to 125 lbs. These are even smaller than the Underjams they replaced!! ...
Customers say
Overall sentiment is mostly positive, with many reviewers praising comfort and softness and reporting fewer leaks than other overnight options. That said, recurring complaints about sizing (too small or tearing), bulkiness, and occasional failure to contain heavy wetting pull the experience down for some children.

Ninjamas Nighttime Underwear for Girls (S/M and P/M sizes) offers comfortable, reliable overnight protection designed to help children feel confident and secure while sleeping. The underwear-style design makes it easy to pull on and off, while the soft, flexible fit allows for comfortable movement throughout the night. It provides good absorbency for nighttime accidents and helps keep bedding dry, making it a practical choice for potty-training transitions or older children who need extra support overnight. The discreet design and comfortable feel make Ninjamas a convenient option for families looking for dependable nighttime protection without the bulk of traditional diapers.

Bedtime confidence matters! We tried Ninjamas Nighttime Underwear, and I was really impressed! They're soft, comfortable, and look more like regular underwear, which helps kids feel more confident at bedtime. After several nights of use, they stayed in place, kept the bedding dry with no leaks, and very comfortable for my child to sleep in. I also liked how easy it is to put on and take off. Overall, I'd recommend Ninjamas to parents looking for reliable overnight protection that's comfortable and prevents leaks.

My nephew loves these! The dinosaur designs are super cute & make bedtime a little more fun. They fit comfortably and do a great job keeping him dry overnight, which means less stress for everyone. They've been reliable for nighttime protection, and he likes wearing them. Definitely a product we would buy again!

I am so glad we received these Ninjamas Nighttime Underwear to try. We are potty training my 3 year old and they have been perfect for our bedtime routine. The quality is undeniably stronger and more durable than other overnight disposable underwear products we have tried. The absorbency is also really great! They are easy to pull up and pull down when he needs to access the potty. The design is cute as well! I would recommend!

I was picked to try Ninjamas Small for free for my nephew. At first he was still adjusting since it was a new fit but after a couple of uses, he loved wearing it! It keeps him dry for long and even if it's full, it does not sag and make the feeling icky as my nephew would describe! It's great!
These are great for bigger kids

I have tried all kinds of pull-ups for my almost five year old, and none have held up like these. They are so absorbent and kept the bed dry all night long. My child didn't get any rashes or irritation which was a worry of mine when switching to something new. I will be buying these from now on.
Life saver for mommies!

My son started bedwetting at night randomly and I was so exhausted doing laundry everyday! Then I came across Ninjamas nighttime underwears and Im in love!! I dont have to worry about pee accidents at night anymore. The scent is very subtle and it is very soft hence no rashes at all. Would 💯 recommend!

I have used this ninjamas at nighttime for my child for a week and it was leakproof. It has a light floral scent but not noticeable after use, the underwear is soft, but, I wished that it was a bit thicker or had a lining inside. I think it would absorb more, if your child sleeps longer than 6 hours, I like the fact it tells you the back with the imprint on them. I recommend these underwear if your child still leaks at night.
