Best Overnight Protection Available!

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!

I didn’t have high expectations for these. My son is 4, autistic, non-verbal and not yet potty trained. He drinks a lot of water throughout the night, so I didn’t think these would hold the amount he pees without leaking. However, they actually have held up. I was changing bedding and washing bedding EVERY Single Day!!

I have a special needs son who is the size of a 7 year old. He wears these at night and loves that they don't "look like a baby diaper". As for absorbency...welp one just went through the washer and didn't bust!

recommend one size larger than weight

our 4yr old is 43lbs. He wears the XL because they hold the perfect amount for him and his night time accidents.

Less leakage than competitor. Comes up higher in front which is good for boys.

Work, but smelly

The fit on these is good for my little one with big thighs. There haven't been any leaks in the few days they've been worn. However, they smell. There's a fake lemony scent that I didn't smell before opening the package, so I can only assume it's intentionally added to the product. Nowhere on the packaging is it disclosed, and I wouldn't have bought it had I known. For that reason I won't buy them again.

reply from Ninjamas

Thanks for sharing your feedback with us, JC, and we're sorry for your disappointment with the scent of Ninjamas. Not everyone agrees on the same level of fragrance, and our research team talked with parents to deliver a scent that offers a fresher laundry-like scent and not a baby-like scent. We will share your comments about the scent, as well as wanting it to be stated on the packaging more clearly, with the team. For more help, please give us a call at (800) 726-7377.

reply from Ninjamas

We know how frustrating leaks are, Kaylynn, so we're very sorry for this experience with Ninjamas. We're here to help and would like to share that size and fit are a huge part of finding the right diaper for your baby, and as you know, babies come in all different shapes and sizes, so diapers fit every baby differently. Our diaper sizes are organized by weight, and since no two babies are the same shape, you will notice some overlap between sizes. In most cases, your baby should be within the weight range for the size you are using, but if leaking is occurring, it may be an indicator to go up a size. So we can help get you and your baby back to leak-free days and nights, please give us a call at (800) 726-7377.
