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

Sam, the reason why the passuk of tzamid pasil is only said to refer to cheres is because it is mekabel tum’ah on the inside, not the outside. To be matzil, though, something which is not mekabel tum’ah at all would also be effective. An example of something not mekabel tum’ah would be a plastic bag larger than 40 sa’ah.
