Many times I have seen that there are those pictures (often from 'professional' sites) where there are really kinda thick diapers. Especially I find them on different tumblr pages, btw.
Anyway, here's a good example:
I was wondering if anyone knows what brands they are/where to get them? They never have any description about that
EDIT: I'm not sure, but isn't this a tena slip? But they aren't usually that thick as here.
