Latex would be better, likely, for against the skin~ except those that are allergic~ as well as being somewhat more usable.

On the other hand, they would be more susceptible to breakage, as well as being harder to source for secondary use & more expensive in the beginning. (It is a rationale to using them, however.) They, also, deteriorate faster (in exposure to air). Though, more repairable. They are a natural product. Butyl rubber has an aroma.

Yet, quite a good idea. Good work!

elastic is in short supply, so we did this with inner tubes:

they're nice because you can make custom cut them to be wider around the head.

curious if latex tubes would offer more compliance. ;-)
