Ironically there's a law against wearing masks in public in Austria
""" kein Verstoß gegen das Gesichtsverhüllungsverbot vor:
Mund- und Nasen-Schutzmasken, Atemschutzmasken; Gesichtsverhüllung zum Schutz vor Frost """
Roughly translates to:
""" It is no violation of the ban on face covering:
Mouth and nose protective masks, respiratory masks; Face covering to protect against frost """
