Review: Great product - My 7 year old son is special needs. 70ish lbs and the store pullups do not fit him anymore. Someone recommended this brand and they are great. A little leaky if he drinks too much but they havnt ripped and holds in all the solids.
Review: Best Overnights ever!! - My 6-year-old still has trouble with night time. We had really good luck with the Pampers 360 pull-ups until we didn't. Not only are getting the Morning free of no weeks... the comfort is great... same as what we were used to with the Pampers. So glad I ran across these as they have saved us from many late night sheet changes. I've been using these for several months now and have only had a couple leaks. Highly recommend!

## Questions & Answers

**Q: Are these larger then the goodnites brand L/XL?**
A: They're nowhere near close to being the same size as Goodnites L/XL., Even Underjams L/XL were bigger than Ninjamas L/XL.

**Q: My son have best friend he wear to can he use to yes are no**
A: It does depends on how to yes or wear in the before if he doesn't go after or look more like

**Q: i have autism will they fit me im 175 pounds...?**
A: No, these would not be a good fit for your size. My son weighs 110 and they are a perfect fit.

**Q: Do these have refastenable sides?**
A: Thank you for your question. Our Ninjamas have tear-away sides to remove a soiled diaper without making a mess. We'd be grateful for the opportunity to help you further. We hope you will find a moment to call us at 1-833-NINJAMA.
