I am not sure how they do it, but they work. Our son was waking up wet almost every day so we gave these a try. They work!

These diapers work very well in absorbing all of the yuck you don't want to irritate you baby when he sleeps. We also used them on long trips.

Impossible to overfill this diaper. Saves having to change the sheets every morning. Does exactly what it says it does.

i never would have thought they would hold my baby, but they did and everything stayed where it should.

these diapers work realy good at night my son will go to bed at 7 and wake up at 7 and no mess at all

WE love these when we are traveling with our little ones. This prevents us from stopping and having to clean out a wet carseat!!!

My daughter is 7 months old and is sleeping through the night, we have yet to have a leaky diaper! LOVE the Huggies Overnight Diapers.

[This review was collected as part of a promotion.] Huggies OverNites fit my baby very well and kept my baby dry over night

Huggies makes the best baby diaper. No leaks even during the night! No more waking baby to change the sheets!

Had problems with leaks at nights. Then I switched to Huggies Overnights and didn't have anymore leaks.
