The New Rules of Apparel: PFAS, What’s Changed, & What It Means for You

In this panel conversation from Blister Summit 2025, we discuss why all of your outdoor apparel recently changed — and how that will impact your own experiences.

Specifically, we’re talking about the ban on PFAS chemicals; why they’d been so extensively used in outdoor apparel (and far beyond); the real-world performance differences between them and new PFAS-free alternatives; and what you need to know to make the most of your own apparel.

To cover all of this, we brought together an excellent panel of industry professionals, including Eric Wallis (Patagonia), Dan Abrams (Flylow), Tom Mason (Ortovox), and Ross Herr (Rab).
