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.

Comparison goodnites XL vs ninjamas XL boys

I have our little guy use these at bedtime. He drinks a lot of water and this helps a lot in case of accidents. These seem softer and more roomy than other ones we've tried. I think they are a bit less expensive too. Either way, he is comfortable when he sleeps and the mattress is safe. I would highly recommend these if needing a pull-up.

Very comfy and absorbent

Excellent nighttime protection! Better than any brand I have used on my grandson. The waist has a better fit and the diaper area is more absorbing than the leading brands and you can not beat this price! I know they don't have the logos the other brands do but my grandson don't care and neither does the trash can! Exceptionally great quality!

Best Overnight Protection Available!

Very useful if child is sick! I bought size S/M for a 40 pound 2.5 year old. They fit well. They fit higher up on the tummy than expected but that's not a problem. I have yet to discover a leak! They work well if child has diarrhea from the flu etc! They did not leak, whereas parents choice pull ups did. They don't look like underwear in person. My only complaint is the strong scent.

Useful when child is sick!

[This review was collected as part of a promotion.] I have two daughters that are using these currently ages 6&4. The 6yr old has been diagnosed with nocturnal enuresis and we have tried regular nighttime pull-ups on her. She says that these feel more comfy and that they hold more of her pee if she has an accident at night. She has asked me to get more of more them when we run out.

Ninjamas pull-up review

I like the absorption they have. They are great at night while we potty train!

Dry Nights

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!!
*Sides ripped while being put on!! While the updated sides are more like the Easy Ups and feel as soft as the Underjams, they ripped half way up my child's legs being put on!!!
*They leaked!!! After getting the first box and pack opened for my son to try out, they didn't even absorb nearly half of what the Underjams would have...

I'm returning the other 2 boxes I bought to the store for a refund, and have contacted you directly for a refund on the box that is opened that we refuse to use now... Seriously disappointed in these, had such high hopes for something that was supposed to be better - especially from Pampers!!

SERIOUS ISSUES with new Ninjamas!!!

Ninjamas

This product did not work for us. We have used pull-ups and needed to love to the larger size for our ASD child. Both nights wearing these was a total fail. I normally love pampers products so this was very disappointing.

Disappointed - loyal pampers shopper
