1m - Butter Suedecloth
Suedecloth is used as the layer closest to baby's skin, it is a synthetic fabric so does not absorb any moisture, but instead wicks it through into the absorbent part of the nappy, and away from baby's skin. Because it does not absorb moisture, it feels dry, so keeping baby's skin dry.
Microfleece is used for the same purpose. It's a matter of personal preference as to which one you use.
