I use either a Sandman which is never wet on the outer, let alone the cover, a Keester Kover AIO which is NEVER wet (windpro outer) or a VBSN like Shannon which is never wet on the outer or the cover either. BBH are always satched so we dont' use them at night anymore. A well boostered windpro or windbloc Honeyboy also goes well at night for us. I don't use microfleece in my nappies anymore - compression wicking is too common (and I don't like it as it's not a natural fabric but that's another story for another time!).

You should check out Buyforbaby as they often have night nappies up.
