Any sources or psaks about wearing a protective mask outdoors on Shabbos? Is it allowed where there is no eruv?
Rav Asher Weiss wrote a teshuva concerning wearing gloves and a mask in a reshus harabim in a kuntres on the Corona Virus. It's siman 9. He comes out to be lenient for both, but suggests it may be better to put one's hands in pockets and use the clothing one is wearing to block their mouth to avoid any issues.
Per article in theyeshivaworld Rabbi Chaim Kanievsky ruled that currently, since one is obligated to wear a mask due to the guidelines – it is considered a malbush [article of clothing] and one must wear them even on Shabbos and there is no concern of carrying.
This was received from someone who heard from someone who... Take it with a grain of salt. I’m only posting it because it conforms with the opinion of Rav Chaim Kanievsky posted here previously.
In order for one to wear a mask outside on Shabbos where there is no eiruv, one must wear the mask in its usual position over his mouth and nose--and not lower it to his chin or below—notwithstanding that it may be uncomfortable. Otherwise, the mask would constitute a masui—and cannot be worn outside on Shabbos. This p’sak has been confirmed by HaRav Shmuel Kamenetsky, Shlita.
Not a Psak Halacha. Just theoretical.
Based off the Gemara in Shabbos 59, it seems that (aside from pkuach nefesh) it'd be mutar to go out wearing a anti-virus mask, because (it's not a masui/burden) the folks wearing it are respectable people (consider/care about themselves) and therefore they wouldn't take it off in public (due to carona & a 6ft distance protocol). Also, aside from it not being a masui, there are masks being made that are essentially tachshitim/ornaments and thus render them Mutar as well...
Aside from Dina D'malchusah Dina i'm not sure. Although the LAW where i live, is that one may not be in public without a mask.
Rav Yitzchak Abadi ruled that wearing a surgical mask on shabbos outside is prohibited.
