Gore-Tex Rain Jacket
High risk. Gore-Tex waterproof technology typically uses PFAS-based treatments.
Gore-Tex rain jackets use specialized membranes to repel water, technology that historically relied on fluorinated compounds for performance.

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Azo dyes and colorant toxicity
Outer and inner fabric layers of Gore-Tex jackets are dyed; if OEKO-TEX or Bluesign certified, azo dyes and heavy metals in pigments are restricted. Non-certified versions may use conventional dyes with higher risk of amine byproducts.
Antimony in synthetic fibers
Gore-Tex outer and lining fabrics are typically polyester or nylon; antimony trioxide is a common polyester catalyst. If product is not certified, antimony leaching risk is low from wearing but increases if fabric is damaged or repeatedly washed in hot water.
VOC off-gassing from laminate adhesives
Adhesives bonding the Teflon-type coating membrane to fabric layers may contain volatile organic compounds. Off-gassing is typically minimal after factory curing but can increase if the jacket is stored in warm, enclosed spaces; air jacket before first wear.
What’s reassuring
Formaldehyde / VOCs
Gore-Tex jackets are typically finished with minimal formaldehyde-based resins because the Teflon-type coating membrane itself provides the water-repellent function. No established reports of formaldehyde contamination in Gore-Tex apparel.

Gore-Tex rain jackets are not flame-retardant treated as standard; this hazard class is not relevant to this product type.

What it's made of and why it matters
Gore-Tex rain jackets consist of a microporous Teflon-type coating (polytetrafluoroethylene) membrane laminated between outer and inner fabric layers. The Teflon-type coating membrane itself does not off-gas or degrade under normal wearing conditions because it is sandwiched and protected. However, Gore-Tex jackets have historically been manufactured with PFAS-based water-repellent coating (water-repellent coating) coatings applied to the outer fabric to enhance water shedding. These water-repellent coating chemicals are the primary non-PFAS concern for this product category.
The brand's record and disclosure
Gore-Tex (W. L. Gore and Associates) has faced sustained pressure over PFAS use in their manufacturing and product treatments but has not published comprehensive disclosure of which specific PFAS alternatives are used in current jacket water-repellent coating formulations. The company announced commitments to phase out legacy PFAS (notably C8 PFOA) but has been ambiguous about transition timelines and alternative chemistry. Third-party certifications such as Bluesign and OEKO-TEX on some Gore-Tex products indicate restrictions on certain hazardous substances, but PFAS restrictions in these standards are limited. No major recalls for non-PFAS hazards are on public record for Gore-Tex apparel.
How it compares in its category
Gore-Tex membranes are the industry standard for waterproof-breathable performance and command a premium price. Alternative brands using Teflon-type coating-free membranes (eVent, Polartec, or polyurethane-based systems) exist but often compromise durability or breathability. Most mainstream waterproof jackets in this performance tier contain some form of PFAS in the water-repellent coating finish; Gore-Tex is not uniquely worse but is not a clear leader in PFAS transparency compared to smaller eco-focused brands. Budget alternatives with polyurethane laminates may off-gas VOCs initially but eliminate Teflon-type coating entirely.
If you buy it
Wash your jacket regularly in cool water with minimal agitation to reduce water-repellent coating breakdown and shedding; avoid dry cleaning, which can strip treatments. Do not tumble dry on high heat; air dry or use low heat to prevent thermal stress. Replace the jacket if the laminate delaminates or inner fabric tears, as water will compromise the barrier. If PFAS exposure is a primary concern, prioritize jackets with OEKO-TEX or Bluesign certification, or consider non-laminated shells with chemical-free water-resistant treatments as a compromise on performance.
