Then I would advise wearing whatever you feel comfortable with and having a disposable mask in your pocket just in case there's a jobs-worth or inspector about. In any resort I've been in this season, as long as the building isn't fully closed, they haven't been enforcing anything. Verbier / Zermatt etc base stations are probably a bit more picky as they'll have more pressure on them, but smaller ones are still very casual.
I've just recovered and am triple jabbed so I'm not too worried about catching or passing on, more that I dont want to be turned away from anything!
