Lolla the article refers to microfleece as a liner, which is different from a booster.
A liner wicks moisture away from the baby's skin and keeps them dry.
A booster is added to a nappy for more absorbency. Some boosters are topped with microfleece which is placed against the baby's skin doing away with the need for the liner.
um, the person who suggested that microfleece wouldn't be absorbent in a booster (which it wouldn't) is responsible for maintaining the ozcloth site and would have probably written or edited the article you are referring to
