reply from Ninjamas

We're sorry to hear the Ninjamas Nighttime Underwear didn't fit your grandson as you'd expect, Becky. While weight is a good guiding factor in choosing the right product, we recognize that children come in all shapes and sizes. So we can see how best we can help, please call us at 1-833-646-5262 when you have a moment.

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.

Great upgrade from large size Pampers pull-ups 360

this is a great next size for those using larger size pull-up cruisers the small to medium size is the next step up and it's less expensive than the Pampers brand Very good product

worth it

We were using cheaper brands and kirkland size 6 and my boy was still wetting through onto the bed sheets. Ever since switching to these in size Sm, we've had 90% less leaks into the bed. worth the higher price.

Best overnight pull ups in my opinion!!

I love these pull ups! They rarely ever leak, the fit is amazing and so stretchy they truly conform to the body! I wish they hadn’t stopped selling them in store

Fancy advertising does not match product

These were “guaranteed to not leak” and the first thing that happened was leakage…and not just a little. These were more hit and miss than our regular night times-do NOT recommend….

Don’t waste your money

I was excited to try these Ninjamas in hopes of no more leaks at night. They disappointed me big time. First night leaked through worse than the other brand I’ve used. Will definitely not be buying anymore

Horrible!

These things are horrible! They aren’t as thick in the front for boys as the underjams were! I have had to wash sheets DAILY due to leaks! PLEASE BRING BACK UNDERJAMS OR REVAMP THESE!!!!

These don’t do near as good as what we’re used too! They leak %26 rip very easily putting them on. We have decided to stick with goodnights, they are the best in my opinion!

Comfortable, cute and leak proof

My kids love the Ninjamas. They use them at bedtime and have never had issues with leaking. They are comfortable and have cute designs that look less like diapers and more like underwear.
