Key takeaways
- PFAS-free (PFC-free) gear avoids per-/polyfluoroalkyl substances — persistent 'forever chemicals'.
- PFAS were long used in DWR finishes and membranes for water and stain repellency.
- They persist in the environment and raise health concerns, driving a phase-out (and new regulations).
- PFAS-free DWR and membranes are now standard goals, though early versions were less durable.
PFAS = per- and polyfluoroalkyl substances; PFC = perfluorinated compounds.
What PFAS-free means
PFAS-free — also called PFC-free or fluorocarbon-free — describes gear and finishes made without per- and polyfluoroalkyl substances. PFAS are a class of synthetic chemicals long used in durable water repellent (DWR) coatings and some waterproof membranes because they repel water and oily stains exceptionally well.
Why they’re being phased out
PFAS are ‘forever chemicals’: they’re extremely persistent, don’t readily break down, and accumulate in the environment and in living organisms, with mounting evidence of health and ecological harm. As a result, outdoor brands have shifted toward PFAS-free alternatives, and regulators in the EU and parts of the US are increasingly restricting or banning them.
A shopper choosing a rain jacket picks one with a PFAS-free DWR — getting reliable water repellency without the persistent fluorinated chemistry — and maintains it with a PFAS-free wash-in treatment to keep the finish working.
How PFAS-free performs
Early PFAS-free DWR was less durable and weaker against oily stains than long-chain PFAS versions, but the technology has improved a lot. For most users, modern PFAS-free finishes work well — especially with proper care and reapplication — and the environmental benefit is significant. It’s part of the same responsible-chemistry push reflected in standards like bluesign, and applies even to premium membranes like newer Gore-Tex ePE.
The bottom line
PFAS-free (PFC-free) marks the outdoor industry's move away from persistent 'forever chemicals' in water-repellent finishes and membranes, driven by environmental and health concerns and tightening regulation. Early alternatives sacrificed some durability, but modern PFAS-free DWR performs well for most users — making it both a responsible and increasingly standard choice.
Frequently asked questions
What does PFAS-free mean?
PFAS-free means a product is made without per- and polyfluoroalkyl substances (PFAS, also called PFCs) — synthetic chemicals long used in water-repellent coatings and some membranes. PFAS-free gear uses alternative chemistries to repel water without these persistent compounds. The terms PFC-free and fluorocarbon-free mean essentially the same thing.
Why are PFAS being phased out of outdoor gear?
PFAS are extremely persistent — 'forever chemicals' that don't readily break down — and accumulate in the environment and living organisms, with growing evidence of health and ecological harm. As a result, outdoor brands have been moving to PFAS-free alternatives, and regulations in places like the EU and parts of the US are increasingly restricting or banning them.
Is PFAS-free DWR as good as the old kind?
Early PFAS-free water-repellent finishes were generally less durable and less effective against oily stains than long-chain PFAS versions, but the technology has improved significantly. For most users PFAS-free DWR performs well, especially with proper care and reapplication, and the environmental benefit is substantial.
