Does not hold liquid

These unfortunately did t hold enough liquid or possibly none at all. Maybe it is my kid but the bed was soaked.

We understand the frustration when your kiddo has leaks, and we're sorry this is happening, Renee. Size and fit are most important when ensuring your little one gets the leak-proof, gap-free fit they need with Ninjamas, and because little ones come in different shapes and sizes, there may be an alternative style that works better for them. Please call us so we can learn more from you and assist you further at 1-833-NINJAMA (646-5262).

We use these at night for our son, and they work really well. Highly absorbant, good quality, and durable. 10 out of 10 for us! You can tell a difference with these.

Best Overnight Protection Available!

Excellent nighttime protection! Better than any brand I have used on my grandson. The waist has a better fit and the diaper area is more absorbing than the leading brands and you can not beat this price! I know they don’t have the logos the other brands do but my grandson don’t care and neither does the trash can! Exceptionally great quality!

Thank you for bringing this to our attention, Janna. This isn&#39;t something we&#39;d expect, as our products undergo regular inspections to ensure you receive them in perfect condition. If your child is 95&#43; lbs., Ninjamas Nighttime Underwear should provide a leak-proof, comfortable fit, and we&#39;d like to gather some details from your product to share with our Quality Team and assist you further. Call us at <br />1-833-NINJAMA (646-5262).
