Warnings: Keep away from any source of flame. Ninjamas nighttime underwear, like almost any article of clothing, will burn if exposed to flame. To avoid risk of choking on plastic, padding, or other materials, do not allow your child to tear the pant, or handle any loose pieces of the pant. Discard any torn or unsealed pant, or any loose pieces of the pant. To avoid suffocation, keep all plastic bags away from babies and children. If you notice gel-like material on your child's skin, don't be alarmed. This comes from the nighttime underwear padding and can be easily removed by wiping your child's skin with a soft, dry cloth

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!

I have a special needs son who is the size of a 7 year old. He wears these at night and loves that they don't "look like a baby diaper". As for absorbency...welp one just went through the washer and didn't bust!
