Ninjamas bed wetting pull ups are made by Procter & Gamble who also makes Luvs diapers as well as Pampers Diapers.
The Ninjamas are made by the same company who also makes Pampers Underjams.
Ninjamas are made for ages 5 to 12 years old.
The Ninjamas can work for some kids who are not really heavy wetters although for others who wet heavier at night they tend to leak.
My 7 year old son tried wearing Ninjamas for bed wetting and they held some but they began to leak on him because he's a heavy wetter at night.
So instead he wears regular diapers which are Pampers Cruisers size 7 diapers which hold up better to his wetting.
If your kid will fit into regular tape on diapers such as pampers or other brands then the tape on diapers are much better than pull up style bed wetting diapers.
You can also buy tape on Youth Diapers as well for kids who are too big for toddler diapers.
Even Luvs diapers now is making a size 7 for older kids and a size 7 Luvs should easily fit a kid up to around 8 years old if they are on the skinny side.
My 7 year old even wears his pampers cruisers size 7 diapers when on road trips or when away from home in case he can't get to the toilet.
They hold up really good and he's comfortable in them.
