Yes Pampers do make overnight diapers.
They have Pampers Swaddlers which my Nephew wears at night and they work great and keep him dry and hold up to heavy wetting.
Huggies has good overnight baby diapers too and even Targets brand of Up & Up diapers are all good diapers for overnight use and even sometimes during the day when you're out and about with your baby or toddler and cannot change them right away.
