Assuming you want something easily removable for when you come to do the
outer stone cladding, you could use Tyvek held down with battens, which
would not look pretty, or corrugated 'iron' or plastic as cladding (the
corrugations would provide ventilation to 50% of the wall surface, provided
you have a small gap at top and bottom) which would keep the weather off.

Corrugated iron painted would look reasonably presentable in a sheddish sort
of way.
