Reply To: PHOTO: Orthodox Jewish Man Covers Himself In Plastic Bag On Plane

I don’t see what this bag would accomplish al pi halakha.

Ironically, the issue came up recently in the daf on Berachos 19 and Eruvin 31.

A proposal to have kohanim hermetically seal themselves was proposed in the past, but rejected, IIRC.

I don’t see how a bag can eliminate the issues with tuma involved.
