Diaper size confusion

My son is 11 months old. He has been in size 6 diapers but is now peeing out of them constantly. Mainly the overnight diapers, I will get him up and he is SOAKED because he overfills it. And he won’t even be in the diaper for more than 5 hours before it happens. I’m so lost on what size to move into, I know that pamper cruisers have a size 7, but it doesn’t look like they fold out all the way, it seems like it’s a pull up type design?

What should I move my son into? Especially for over night leaks?
