Great for older/larger children

I like that these nighttime pull ups will fit older/larger children and does a great job in containing those overnight accidents. When my child is dry overnight, he can often wear them the next night without worry of leakage. Most times, Ibotta or Walmart Plus offers cash back on these pull ups as well.

Ninjamas

This product was purchased as part of a promotion, the opinions are my own. My son has used the Ninjamas for 3 nights and has wet the bed once while wearing them. He wears the S/M and weighs 36 lbs. He loves the Ninjas on the front and I wish they put a ninja on the actual product itself. Overall I would purchase this product again.

Comparison goodnites XL vs ninjamas XL boys

I was skeptical at first buying these diapers for my toddler, but I am really impressed. NO leaks, higher waist than goodnites, and they are more comfortable ( feels softer ). For others saying that ninjamas is smaller than goodnites XL. I posted two pictures side by side of both brands to compare. They are the same size. The only difference is that one is bulkier and the other is longer when packed. In my opinion ninjamas has a better quality.

Great for big kids

I have a big 4 year old wears size 7/8 kids clothing. The L/XL fit him perfectly. He only wears them to sleep, and loves how comfortable they are. They are durable we use one or 2 a week, as he doesn't wet himself often you can reuse them. The only negative is that they do tear easily at the sides sometimes.

They leaked every time :(

They leak. My son is 67 lbs so I got size L (64-95 lbs). But, I think they were just too big and gapped open around the legs when he moved around at night. There was never a time he had an accident that they didn’t leak and I bought a very large box.

reply from Pampers Response

We're sorry to learn your son's had this experience, as we always hope every nightime Ninja-in-Training will wake up ready to take on the day, thanks to a restful, dry sleep. Like you noted, he may be between sizes, and we're so sorry to about that. When he puts on the pant, before going to sleep, it might help to have him run his finger along the leg cuffs, making sure that everything is sitting correctly. This may keep everything contained, and lead to ready-to-rumble, ninja-style, every morning. We hope you'll call us for more help. We're available Mondays-Fridays, from 9 AM to 6 PM, EST. Our number is 1 (833) 646-5262.

Weight Lifters!

A weight has been lifted off our shoulders when we found these. We have a 7yr old autistic son that isn't potty trained yet and he is a big boy. Until the Ninjamas we always had leakage, blowouts, meltdowns etc. The Ninjamas are soft and moves with his body and keep things where they belong. They even look more like underwear then other brands. Which means we're also spending less money on pullups because we are using less of them. The only thing i could possibly say as a negative would be that they're not available in all stores.

Last option

If a child pees alot it is not a good diaper & it doesn't hold urin in well. Every time I check my child at night he is soaked unless I change him 2 to 3 times a night. I hate waking my child up to change his clothes & even his bed sheets cause he pees in them. Goodnights are way better & I don't have to go through that. They are more expensive but a way better brand.

reply from Ninjamas Team

We're sorry to hear about the leaks. Ninjamas were designed so the family could get a good night's rest, so it's disappointing to hear you have to wake your son up during the night. It's possible the next size may last longer so you can all get the rest you need. We’d like to learn more about your experience so we can help you further. Please reach out to us when you can by calling 1-833-NINJAMA.

Not good!

These are very thin, thinner than Parent's Choice. Every night my children have worn these, they have leaked - significantly. I will definitely be switching back to Goodnights. I ordered the large boxes in S/M %26 L, hoping they would be good products because they were cheaper. I wasted $60.

Every little Ninja-in-Training should wake up dry, and we're sorry to learn about this situation. Our Quality Team assures us that all Ninjamas meet our high standards, so what you're describing isn't expected. Leaks can be the result of a poorly fitting Ninjamas pant, check to make sure your child’s in the best size. We suggest having your child run their finger around the leg cuffs, making sure they’re correctly positioned. This may stop any leaks. Know we're here to help, and we encourage you to call us for the best assistance. We're here Mondays through Fridays, from 9 AM to 6 PM, EST. Dial us up at 1 (833) 646-5262.

Weak sides tear out

I can't review the absorbency or comfort of these, although they look nice and are soft to the touch, the sides tore out when my 90lb son tried to put them on, twice.... the weight says upto 125 and he's never torn out of other brands of the same size. I'm very disappointed in the quality and durability.
