Wool
Wool backing is water resistant because wool will absorb several times its weight in water before feeling wet.
Wool can be lanolised to repel liquid, but this could not be done in an aio style pad, as it would not be possible to lanolise only the backing of the pad. lanolised inserts for pocket styles, or lanolised base-insert pads could be made however.
