Slim

This is an index of popular medical and adult baby disposable diaper brands, sorted by advertised absorbency. Where different absorbencies are quoted for different sizes, the absorbency of the medium size is listed. I make no claims regarding the accuracy or methodological consistency of these ratings.

I’ve sorted them into different usage categories. If you mess, you may want to consider going up at least one category (e.g., if you would normally need ‘Daytime Plus’ diapers during the day, you might want to go up to ‘Overnight’). This is because messing also uses some absorbency.

Slim

I’ve called these diapers ‘slim’ because the only reason to wear them is if you really find that you need slimline protection.

These diapers aren’t quite thick enough to use as overnights if you’re a bedwetting adult, but if you’re a heavy pantswetter or if you just want to give yourself an extra hour or so, these are for you.

These are great if you’re a tall/solidly built bedwetter, or if you’re going to be riding in someone’s expensively upholstered car, or if someone else is changing your diapers. The point is, they’re the bulkiest but also the most absorbent diapers you will wear.
