| What it means | No 'forever chemicals' (PFAS) used |
| Where PFAS were | DWR finishes, some membranes |
| Why avoid | Persist in environment & body; regulated |
| Replacements | PFAS-free DWR, ePE membranes |
PFAS-free means a product is made without per- and polyfluoroalkyl substances — the ‘forever chemicals’ long used in durable water-repellent (DWR) finishes and some membranes. PFAS persist in the environment and human body and are increasingly regulated, so outdoor brands are switching to PFAS-free DWRs and membranes (like Gore-Tex ePE) that aim to match performance without the environmental harm.

Drives PFAS-free DWR and membranes like Gore-Tex ePE; tracked by standards like bluesign. Use PFAS-free products when reproofing.
Frequently asked questions
What does PFAS-free mean?
PFAS-free means a product is made without per- and polyfluoroalkyl substances, a large class of synthetic chemicals nicknamed 'forever chemicals' for how long they persist. In outdoor gear, PFAS were widely used in water-repellent (DWR) finishes and some waterproof membranes; PFAS-free versions avoid them.
Why are PFAS a problem?
PFAS don't readily break down, so they accumulate in the environment, water, wildlife, and human bodies, and some are linked to health concerns. Their persistence and growing regulation have pushed the outdoor industry to phase them out of DWR treatments and membranes in favor of PFAS-free alternatives.
Do PFAS-free finishes work as well?
Modern PFAS-free DWRs and membranes (such as Gore-Tex's ePE membrane) have improved greatly and perform well for most users, though some early PFAS-free DWRs needed more frequent reproofing and resisted oily stains less. The trade-off is generally considered worthwhile given the environmental and health benefits, and performance continues to advance.
