What is this product?
Waterproof/breathable rain jackets and hardshell outerwear (Gore-Tex, eVent, etc.). Durable Water Repellent (DWR) finish traditionally uses PFAS (C6/C8 fluorocarbons). Membrane-based waterproofing (ePTFE in Gore-Tex) is itself a fluoropolymer. PFAS detected in sweat wipe tests from jacket wearers. Some brands transitioning to PFAS-free DWR (wax, silicone, or dendrimer-based). EU PFAS restriction proposal could ban fluorinated DWR by 2027.
