They are sized so much smaller than Underjams. My son just moved up into the underjams L/xl and they were bordering on too big but the s/m were too small. He is 55lbs. The new ninjamas fit him but he will not be able to wear them for long. I expected he could wear these for several years until he reached at least 100lbs, but with the current sizing, that will not happen. My son has cerebral palsy and wears these 24/7. I truly hope you will consider resizing them or adding an XXL option. My son is 44” tall and 55lbs, so in no way consider large or chubby and the L/XL fit perfectly. This means for larger children, they will fit too small. As for the technology, they are great! No leaks! Love the waistband! I am disappointed that the price increased a little and the count per box decreased by almost 1/4.

[This review was collected as part of a promotion.] I have to say this works pretty well my son still felt like a big boy and was begging me to put on his ninjamas. He is potty trained but occasionally has accidents when in a deep sleep which he gets really sad about in the morning times, these really helped him not feel that way.

[This review was collected as part of a promotion.] My son has been using Ninjamas Nighttime Underwear for about a week now and we haven't had a single leak! The underwear has nice stretch in the waist and legs but still prevents leaks. The underwear notes having "odormask" but doesn't seem to be highly scented, which I really appreciate. I wish the front and back were a little more obvious but overall I love this product and would definitely recommend it.

[This review was collected as part of a promotion.] My daughter is potty trained during the day but sometimes still sets the bed at night. We had been buying Pampers or Huggies pull-ups (whichever was on sale at the time) and they were ok. Weve found that they were stiff and the sides would come apart sometimes. When we got these in the mail, we were actually excited. She really liked the design and said they smell good. When she pulled them on at night, she said they were much more comfortable. She had a cold the other night which made her very thirsty for some reason. She drank 12 oz before bed (which isnt normal but, she was sick so we figured she needed it). She woke up with a full pull-up so I think its safe to say these work very well. I think we found our new brand. Accidents dont happen often but its nice to know that when they do, she can wake up dry and comfy.

[This review was collected as part of a promotion.] My kid loves these. They are super comfortable on him and they don't leak. These have completely met our expectations. I wouldn't change anything about this product, except maybe making them available at walmart stores.

[This review was collected as part of a promotion.] I think that this product works very well, but my six year old doesn't wet the bed very often. Thought they were more like nighttime underwear with absorbant material inside and my son was very unwilling to try them out. He hasn't been in nighttime diapers for about two and a half years, but with his regression to bedwetting lately we decided to try these. They do work quite well so the three stars is because they look too much and he says feel like a diaper so wasn't happy at all.

[This review was collected as part of a promotion.] As much as I wanted to love these, these were way smaller than we expected to be for the weight limit provided. The L/XL needs to be a little larger. I did love that they resembled real big kid under garments.

[This review was collected as part of a promotion.] The design is super cute! I love the form fit waistband so it doesn't gap open and leak. I love the fact there are no parabens or latex! They are breathable so your child won't get a rash and have quiet cloth material so it doesn't make noise while they are sleeping and wake them up. They are very easy to pull up and down for learning. I like that the leg holes don't gap open and leak. The price is great for what you get! The only thing I would say is that the color is very dull compared to the pictures online, but that may be a good thing because you don't want heavy dyes or colors absorbing through your child's skin.

[This review was collected as part of a promotion.] At 1st look, I was wondering whether my daughter would feel like a "baby" in these. But I was wrong she loved the print and the texture. She wasn't embarrassed to wear these. I think these are a little expensive but not too much. I would buy this product again.

[This review was collected as part of a promotion.] we got these to use for my oldest son who's about 8 years old. He's on the spectrum and has a hard time staying dry at night. we typically use some kind of nighttime pull up but decided to try ninjamas. I was pleasantly surprised to see that there was no gross year and smell no matter how soaked it got, and none of it leaked onto his bed. I'm still not sure if this will help him transition to staying dry at night but will take it one step at a time.
