Came across this interesting article this evening about the PFAS and forever chemicals being used in waterproofing gear like waders and jackets. The article mentions several high end companies using these chemicals and I assume Sitka and Chene do to. It's worth the read amif you have a few minutes.

So basically, same as global heating!
