TL/DR: A lightweight, quick fix for hooded sensory deprivation play.
We had dabbled with some mummification play prior to this and didn’t have a proper hood, opting to use some clothes as a makeshift solution. It wasn’t very breathable and paired with the mummification, did not bode well in terms of claustrophobia. I did some searching for a cheap option since we have plans to purchase a very nice quality sensory derivation mask...
