Good but gave skin reaction

These are soft and very stretchy. Only reason I don't give 5 stars is because it gave my fighter a horrible skin reaction.

Verified Purchase

Too scented

Disappointed. These are not fragrance free. The perfume was very pronounced. Caused a terrible rash on our little one. Will not purchase again. The fit was very nice.

okay

[This review was collected as part of a promotion.] The idea of these is good, but theyre so bulky that my daughter did not like them at all. It feels like youre wearing a heavily scented baby diaper. If youre older child has chronic bed wetting issues, Id say theyre a good option. But for the occasional bedwetter its not ideal.

God AWFULL. DONT WASTE YOUR MONEY

Cant give 0 stars. Absolutely abysmal. Product is literally as thick as 10ply papertowels with a gas station plastic bag as a waterproof liner. It can barely fit an average 8 year old - 4'8 and 85lbs, much less the intended recipient, who is 5'10 and 100lbs if he's soaking wet. They are marketed for kids up to 125lbs. Give me a break! I wasted my money and want it back! Now i have to go out and buy something ELSE! DO NOT WASTE YOUR MONEY!

Amazing overnight pull-ups

[This review was collected as part of a promotion.] These pull-ups are great!!! My son needs to wear them while he sleeps and we have had no problem with leaking. He says they are really comfy and soft! He gets really excited because they are "ninja" pull-ups! I would definitely recommend these to any parent that needs a good pull-ups for their children!

overnight protection

[This review was collected as part of a promotion.] these have made a huge difference! Very few if any leaks and my child normally has a wet morning everyday. These have helped my household in so many ways. Thank you for this opportunity to try these out an yes they are completely worth buying.

I really really wanted to love this!

[This review was collected as part of a promotion.] Ive been eyeing these pull ups for my son for a while for his bed time accidents. The sizing is alllll wrong. Hes 96 lbs and the XL size barely pulled up. The material was so soft and he loved it and it surprisingly held his accidents and had no leaks. It works amazing but doesnt fit. Until they fix their sizing I sadly wont be buying these.

Comfortable nights

[This review was collected as part of a promotion.] These are lightweight nighttime underwear, my son seems comfortable with them, they fit well and I find convenient that they goes from small to large sizes, so convenient for older or bigger kids, they also cab be used as potty training pants during the day. They work pretty well, I have not experienced any incident because they do not leak, they keep my son dry and cause no irritation or rash, that is important to know his skin is protected and he can sleep comfortably.

I didn’t know I needed this — until now!

[This review was collected as part of a promotion.] Potty training SUCKS. This helps ot suck a lot less. I know for me personally this is a little on the pricey side but its worth it in my opinion. It definitely helped nights be a bit more tolerable when potty training.

So glad to find these

After my daughter sized out of regular diapers I was left wondering what other parents do (she's in the 90+ percentile for her height and a heavy wetter, so has always been a larger size in diapers... when she turned 2 still needed nighttime diapers but suddenly I realized there's nothing after a size 6!) Then I found these and felt so relieved - they never leak, even after a long sleep and lots of wriggling around. I can't believe the weight range they cover with the larger size - it also made me think about children with special needs who may need diapers for a while longer. The material is soft and not terribly bulky, despite being able to hold a sizable amount of liquid, and easy to pull on so my kid can do it herself. Big fans over here!
