Best diapers for overnight

So my 5 month old son loves to sleep on his front. Some mornings when he wakes up the area on his onesie where his diaper is, is damp and so is his bed. I really try to get him to be a back sleeper but he just wont have it. So im trying to find a brand diaper that can sustain him throughout the night. Weve only tried pampers swaddlers and baby dry. The baby dry helped some but some morning hes still alil wet. Any recommendations. Anyone else have this issue
