You are correct re: Shakedry. What's interesting to me is that it used the now discontinued ePTFE which manufacturing used PFAS in production, but there is still no alternative PFAS-free Shakedry, despite now having an advantage of not requiring a DWR at all.

I would agree that even with the delicateness of Shakedry, or Shakedry-like product, there would still a use case and market.
