    • Great product
Size: Large Unit Count: 34
My 7 year old son is special needs. 70ish lbs and the store pullups do not fit him anymore. Someone recommended this brand and they are great. A little leaky if he drinks too much but they havnt ripped and holds in all the solids.

    • Best sleep diapers that rarely leak.
Size: Small/Medium Unit Count: 44
We’ve been using these for years. They’re durable and rarely leak unless it’s extremely full. These are pull-up style and easy to pull on and off or just rip the sides which is also easy. My son likes to drink 2 bottles of water at bedtime and most nights the bed is dry. My son is 3.5 years, 42” tall and is 37 lbs and wears s/m. They’re a little big but when he was smaller they fit better but he has gotten really long and lean so they’re looser now. All good tho bc they can tolerate a lot of liquid. My daughter also wears them (the pink ones) but she has very few accidents now that she’s older. 7 years, 54” tall, 55 lbs and wears s/m. They’re definitely worth the money over other sleep diapers. I just wish they made an xs/s for the tall and lean kiddos as they’re now less snug. But still great. ... show more

    • The only pull-ups that haven’t leaked on my 4 year old!
Size: Small/Medium Unit Count: 88
My son is almost 5, and we’ve tried so many overnight pull‑ups that leaked every single time. Ninjamas are the first ones that actually kept him dry all night. The fit is snug without being tight, and he wakes up comfortable with zero leaks. If you’ve been struggling to find something that truly works, these are worth it. ... show more

    • Reliable Nighttime Protection for Kids
Size: Small/Medium Unit Count: 88
These nighttime underwear have been a big help for us. They fit well, feel soft, and don’t look bulky, which makes my child more comfortable wearing them overnight. Absorbency is very good most nights we’ve had no leaks at all. Occasionally, there may be slight leaks during very heavy nights, but overall they perform much better than other brands we’ve tried. I also like that they’re hypoallergenic and gentle on sensitive skin. A solid choice for nighttime use, and I’d recommend them to other parents. ... show more

    • BEST overnight protection for toddlers! No leaks!
Size: Small/Medium Unit Count: 88
I’ve tried several brands of nighttime underwear, and Ninjamas have become our clear favorite for my older toddler who isn’t fully potty trained at night yet. These truly stand out in every way. Leak Protection: The biggest win for us is that they never leak. We’ve gone through many overnight products that claimed to be extra absorbent, but these are the only ones that consistently make it through the entire night, even on nights with heavier wetting. No more soaked pajamas or changing sheets at 2 4 am - such a relief! Fit & Comfort: The fit is fantastic. The waistband is honestly one of the best features. It’s soft, stretchy, and really flexible, so it moves with my child without digging in or leaving marks. The leg openings also have a snug but gentle fit that helps prevent leaks without feeling tight. My toddler stays comfortable all night and never complains about them. They’re thin and discreet under pajamas, and they look more like real underwear than a diaper. The fun designs are a bonus too! Performance: They hold up great through long nights, travel, and even nights where my toddler drinks a ton of water before bed. The absorbency and fit have been consistently reliable for us. If you have an older toddler who needs nighttime protection, I can’t recommend Ninjamas enough. They fit well, feel comfortable, and most importantly keep the bed dry every single night. Absolutely worth it! ... show more

These are super good diapers. My 12 year old wears these and the asorbentsie on this is crazy. One morning he woke up with the diaper sagging and when I took it off the whole thing was full but no leaks.

    • Unfortunately scented! False advertising
Size: Large Unit Count: 68
One star because My skin is still itching after opening the box with the heavy scenting of the pull-ups. I am going to have to take a shower to get this crap off my skin. Who wants chemicals placed on the pull-ups that our children wear. Very dumb idea. Please do not scent these pull-ups. In their description they claim “discreetly combats unpleasant odors. Dermatologist tested and hypoallergenic suitable for sensitive skin.” This is a lie. The pull-ups and the box that come in is heavily scented. And it is allergenic because my skin hasn’t stopped itching. This is false advertising. I am concerned that this could cause allergies in children or worse. Pampers makes these so I’m surprised that they’re so dumb. Nobody wants this crappy scenting on their kids skin. Get I the hell off. ... show more
