prevents leaks about 75 percent of the time. Not that great

great protection for overnight no worries about leaking in bed or clothes

My daughter sleeps 12 hrs a night and this diaper has never let us down. No leaking!

These are the best performing diapers! Recommend them.

really work. do not leak. id recommend buying them.

I did not know these existed, I have read the reviews and I am looking forward to trying them out!

they keep my daughter dry all night long, and she sleeps alot

These diapers I have to say are a favorite for us.

We started using the overnight diapers in size 4 a few months ago and they work great.

i have never had a problem with these pull ups leaking at night. also good for long road trips.
