PFAS-Free Waterproof Breathable Fabrics: Rules, Membranes and Finishes Buyers Need to Know in 2026

Buyers specifying waterproof breathable fabrics need to assess the membrane and the water-repellent finish separately. France’s PFAS decree and the EU’s PFHxA restriction differ in scope, thresholds and exemptions. Verify which rules apply to the product and market, and specify the waterproofing, breathability and durability the garment must retain after the agreed care cycles.

This guide is written for the people who have to make that judgement: buyers, product developers and quality managers who specify waterproof breathable fabric. It covers the rules that apply now, the membrane and finish technologies replacing PFAS, the performance gap that remains, and how to write a specification that protects you.

First, what PFAS does in a waterproof breathable fabric

PFAS has traditionally played two roles in this fabric, and confusing them is the most common mistake in the transition:

1. In the membrane. Expanded polytetrafluoroethylene (ePTFE) is a fluoropolymer — a member of the PFAS family — used as the waterproof breathable membrane in many outdoor shells. It blocks liquid water while allowing water vapour to pass.
2. In the finish. Durable water repellent (DWR) finishes, historically based on C8 and later C6 fluorochemistry, coat the face fabric so water beads and rolls off instead of wetting out. If the face fabric wets out, the garment feels clammy and heavy even if the membrane underneath is still waterproof.

A fabric can therefore be “PFAS-free” in one of these two places and not the other. A buyer who asks only “is it PFAS-free?” without specifying membrane and finish separately will get an answer that is technically true and practically useless. Always ask both questions.

The rules: a buyer compliance timetable

There is no single global PFAS ban. There is a sequence of national and EU measures with different dates, scopes and thresholds. The table below is the working timetable as of 13 November 2026.

France: the first hard ban with numbers attached

France is the jurisdiction that has moved furthest, and its approach is the model other buyers should understand first. Law No. 2025-188 of 27 February 2025 banned the manufacture, import, export and placing on the market of PFAS-containing consumer clothing textiles, footwear and their waterproofing agents. Implementing Decree No. 2025-1376 of 28 December 2025, published in the Official Journal on 30 December 2025, gave the ban measurable teeth. The three thresholds do not all measure the same thing, and the distinction matters for how they are tested:

The thresholds apply to consumer clothing textiles, footwear and waterproofing agents placed on the French market from 1 January 2026. They are legal limits on what may be sold — not a specification a buyer invents. A buyer may, however, adopt them as a voluntary purchasing requirement, and may apply them more strictly than the law requires (for example, to products outside the decree’s scope). That is a contractual choice, and it should be labelled as such in the specification rather than presented as a restatement of the decree. The specification template later in this guide does exactly that: it uses the French thresholds as a buyer requirement, not as a paraphrase of the law.

Products manufactured before 1 January 2026 may be placed on the market or exported for up to twelve months from that date — in practice, until 31 December 2026. The exemptions are narrower than a first reading suggests, and they differ by product type:

• Personal protective equipment is exempt where it falls within Regulation (EU) 2016/425 on personal protective equipment — not every garment marketed as “protective” qualifies.
• Armed-forces equipment is exempt.
• Clothing or footwear incorporating at least 20 per cent post-consumer recycled material is exempt only where residual PFAS is limited to the proportion coming from the recycled fraction, and no PFAS has been intentionally added to the product — with documentary evidence of the recycled content’s provenance.
• Professional clothing is not covered by the 2026 requirements at all: it is covered only from 1 January 2030, when the ban extends to all textiles — and professional footwear remains outside the scope even then.

The practical consequence for buyers is immediate: any non-exempt consumer garment within the decree’s scope, placed on the French market after the applicable date, must meet the applicable thresholds. Exceeding the 50 ppm total-fluorine trigger does not by itself prohibit the product — it triggers the evidentiary requirement to establish the fluorine’s source. That distinction does not save a fluoropolymer membrane: a PTFE membrane’s total fluorine exceeds 50 mg/kg by its nature, and where the evidence establishes that the fluorine comes from PFAS, a non-exempt garment within the decree’s scope would not meet the applicable statutory requirements — the determination follows from the source evidence, not from the presence of a fluoropolymer alone. That is why the French measure, more than any other single rule, is forcing membrane change.

The EU: PFHxA limits now, a universal restriction later

At EU level, the measure already in force is narrower. Commission Regulation (EU) 2024/2462, adopted in September 2024, restricts undecafluorohexanoic acid (PFHxA), its salts and PFHxA-related substances under REACH. From 10 October 2026, these substances may not be placed on the market or used at or above 25 ppb for the sum of PFHxA and its salts, or 1,000 ppb for the sum of PFHxA-related substances, in textiles, leather, furs and hides in clothing and related accessories for the general public, and in all footwear for the general public. From 10 October 2027, the same limits apply to other consumer textiles. The restriction does not apply to products placed on the market before the relevant application date. Two points buyers should not miss: the limits apply to the specifically defined PFHxA substance groups, not to all PFAS — meeting the PFHxA limits does not establish general PFAS compliance — and a product can comply with the PFHxA restriction while still containing other PFAS that fall under the French thresholds or a customer’s own specification.

The bigger EU measure — a universal restriction covering PFAS as a group — is still moving through the European Chemicals Agency (ECHA). The Risk Assessment Committee adopted its opinion in March 2026; the Socio-Economic Analysis Committee agreed its draft opinion on 10 March 2026 and consulted on it until 25 May 2026. ECHA expects the final SEAC opinion by the end of 2026. Only then does the file go to the European Commission, which prepares a draft decision for member states. Final adoption is currently estimated for late 2027 or 2028, with implementation not expected before 2029. Nothing in that process creates obligations for companies today — but the direction is unambiguous, and the transition periods and derogations for specific uses are still open. A buyer who waits for the final text before changing specifications will be changing them in a hurry.

There is no EU-wide ban on PFAS in workwear fabric yet. Sweden has proposed a ban on PFAS in consumer clothing, footwear and water-repellent treatments from 1 January 2028, with PPE exempt — a proposal, not a law, at the time of writing.

Testing: EN 17681-1:2025

CEN published EN 17681-1:2025 on 30 April 2025, replacing the 2022 version of the PFAS test method for textiles. The change is in sample preparation: the 2022 method used methanol extraction and targeted primarily freely extractable PFAS, while the 2025 method extracts with methanol and sodium hydroxide — alkaline hydrolysis — which breaks down certain side-chain fluorinated polymers during extraction and releases additional PFAS compounds such as fluorotelomer alcohols (FTOHs). Results with the new method can be more than 100 times higher than with the old method for the same sample. The method is a liquid chromatography and tandem mass spectrometry (LC/MS/MS) method for targeted, mostly ionic PFAS on a defined target list, applicable to all materials of textile products. Three limits buyers should understand: the standard pertains only to targeted PFAS analysis, not to total fluorine screening — a separate total fluorine test is needed where a total-PFAS threshold applies; the companion standard EN 17681-2 (GC/MS) covers certain semi-volatile and volatile neutral PFAS that LC/MS/MS does not readily analyse; and some substances, such as 10:2 and 12:2 fluorotelomer iodides, are not detectable by EN 17681-1:2025 at all and need supply-chain control or another method. The French authorities cite this standard in their guidance. Buyers should name the standard and its version in their specifications — “tested to EN 17681-1:2025” — rather than accepting a generic “PFAS tested” statement, because the method version changes what the result means. And no single test result establishes the absence of every PFAS: the PFAS group contains several thousand substances, and a targeted method can only report on the substances on its list. A “not detected” result means “not detected for the listed analytes at the stated limit of quantification” — nothing more.

Membranes: what replaces ePTFE

The most visible development in 2026 is W. L. Gore & Associates’ introduction of an expanded polyethylene (ePE) membrane for its Gore-Tex product range, as an alternative to the company’s original expanded polytetrafluoroethylene (ePTFE) membrane. ePTFE is a fluoropolymer belonging to the PFAS group; ePE is not. The move matters because Gore-Tex has been the reference product for waterproof breathable performance for decades — when the reference product changes its chemistry, the whole market’s expectations shift.

The alternatives now on the table fall into four groups:

No membrane route is a drop-in replacement for ePTFE in every application. Hydrophilic PU membranes transport moisture by molecular diffusion through a solid film, a different mechanism from the microporous transport of ePTFE and ePE — so their breathability varies with the temperature and humidity gradient across the membrane, and a rating measured in one set of conditions does not transfer automatically to another. Buyers should verify breathability on the specific construction and under conditions that match the intended use, rather than comparing headline MVTR figures measured by different methods. ePE is closer to ePTFE in structure, but it is a new technology at scale, so its long-term durability record is necessarily shorter than ePTFE’s decades of field use — that is a statement about time on the market, not a prediction of failure. Buyers should ask for test data on the specific construction they are buying — hydrostatic head, moisture vapour transmission rate (MVTR), and air permeability — rather than accepting a membrane brand name as a performance guarantee. Our guide to fabric GSM and specifications explains how to read the specification sheet behind those numbers.

Finishes: the harder half of the problem

If membranes are the visible change, DWR finishes are the harder one — because oil repellency, not water repellency, is where fluorine-free chemistry struggles most.

Traditional C6 DWR gave both water and oil repellency from a single chemistry. Fluorine-free (C0) DWR gives water repellency, but according to Prance, a workwear fabric supplier, no fluorine-free finish it has seen gives strong water and oil repellency together. That is one supplier’s assessment, not an independently tested industry benchmark — and it is the honest position for a buyer to work from: garments that only need water repellency can move to C0 now; garments that need oil repellency — food processing, automotive, oil and gas — must be assessed case by case.

The newest attempt to close the gap came on 2 November 2026, when Dow launched DOWSIL IE-5619 DWOR Emulsion, a silicone-organic hybrid chemistry that Dow describes as designed to deliver durable water and oil repellency without conventional fluorinated chemistry. According to Dow, the product is a 30 per cent solids concentrate for conventional textile finishing, intended for natural, synthetic and blended fabrics. Dow reports that the treatment is designed to maintain water and oil repellency after more than 20 domestic laundering cycles, although results depend on fabric construction and formulation, and that it targets oil-based contaminants including cooking oils, motor oil and sebum, as well as water-based stains such as coffee, wine and milk. Third-generation silicone-organic hybrid technology is the mechanism Dow cites. The launch reporting does not disclose the test methods, fabric constructions or performance ratings behind those figures, so they should be treated as manufacturer-reported claims requiring independent validation: whether the product closes the oil-repellency gap in production, at scale, is something buyers should verify on their own fabric rather than take from a launch announcement.

The wash-durability gap is the practical issue buyers feel first. One supplier’s published comparison illustrates the scale of it: Prance, a workwear fabric supplier, reports spray-test results (ISO 4920, 0–100 scale, 40°C wash) on its own workwear fabrics — a fluorine-free finish scoring about 90 for water repellency before washing and about 70 after five washes, against a fluorinated finish at 100 before washing and 80 after ten washes (note the two finishes were measured after different wash counts). Those are a single supplier’s figures, not a standard, so they should be read as an illustration of the gap’s direction and size, not quoted as industry data. Laboratory ratings are also not garment-level performance: a finish’s rating on a test swatch does not guarantee the same result after cutting, sewing and repeated laundering. A spray-test rating measures surface wetting resistance only; it does not establish hydrostatic-head performance, oil repellency or finished-garment durability. The point they make is real: the supplier considers its fluorine-free finish suitable for these applications, subject to validation on the intended fabric and laundering conditions. For garments washed frequently or exposed to oils, the gap is the specification problem. Buyers should set their own acceptance criteria — hydrostatic head, MVTR, air permeability and wash-durability cycles — with agreed sampling and retesting requirements, rather than relying on a supplier’s headline rating.

Palm Equipment Europe, a technical outerwear brand, offers a useful reality check on what “PFAS-free” means in practice. From its 2026 range onwards, all Palm XP 2-layer, 2.5-layer and 4-layer waterproof garments are made with no intentionally added PFAS, using C0 DWR and PU-only membranes; by 2025, around 88 per cent of its supply chain was already free from intentionally added PFAS. The company’s own wording is careful: “no manufacturer can honestly guarantee the complete absence of PFAS in a jacket”. Trace contamination from shared equipment, recycled inputs and the environment means “no intentionally added PFAS” is the honest claim. “Zero PFAS” is not.

Writing the specification: dual-threshold acceptance

The most useful thing a buyer can do in 2026 is to write the rules into the specification, rather than relying on a supplier’s general assurance. The template below combines the two regimes that actually bite today — the French thresholds and the EU PFHxA limits — into a single acceptance clause. It is a voluntary buyer requirement, not a restatement of the law: the French thresholds are legal limits for products sold in France, and a buyer who adopts them for other markets, or applies them more strictly, is making a contractual choice. Each threshold below is applied as a buyer requirement independently of whether the underlying rule applies by statute to the product in question: requirements (a)–(c) adopt the French decree’s numbers as a contractual test for consumer clothing textiles, footwear and waterproofing agents placed on the French market (and, at the buyer’s option, for the same product types sold elsewhere); requirements (d)–(e) adopt the EU PFHxA limits as a contractual test for clothing, accessories and footwear for the general public, and for other consumer textiles from 10 October 2027. Adopting a threshold as a contractual test does not extend the underlying statute’s scope — it borrows its numbers. Each requirement is matched to the evidence that proves it, because no single test covers them all. Adapt the wording to your own legal advice; the structure is the point.

Specification clause (template). “The finished fabric and garment shall contain no intentionally added PFAS in either the membrane or the durable water repellent finish. The finished product shall meet all of the following: (a) any individual PFAS ≤ 25 ppb by targeted analysis to EN 17681-1:2025, excluding polymers, with documented laboratory confirmation of analyte coverage, limits of quantification and polymer exclusion, and any complementary method necessary to establish compliance with this threshold; the applicable analyte list shall be defined in advance, with complementary validated methods for substances outside the standard’s analytical coverage; EN 17681-1:2025 applies only to its defined target list, and acceptance under this requirement is conditional on documented coverage of the applicable analytes; (b) sum of PFAS ≤ 250 ppb by targeted analysis to EN 17681-1:2025, excluding polymers, with the same documented laboratory confirmation as in (a); the reported sum applies to the identified analytes, not all PFAS; acceptance under this requirement is contractual acceptance within the validated analytical scope and shall not be represented as a determination of statutory aggregate-PFAS compliance; where aggregate analytical coverage is insufficient, the laboratory report shall classify the result as indeterminate, not compliant; (c) total fluorine ≤ 50 mg/kg by total fluorine screening, as a voluntary contractual screening criterion separate from the statutory requirement to establish the fluorine’s source when the trigger is exceeded; where total fluorine exceeds 50 mg/kg, the operator shall establish the source of the fluorine by a laboratory-validated complementary analytical approach demonstrated to be fit for the relevant polymeric PFAS, with disclosure of its scope, recovery, limitations and limit of quantification — the statutory 50 ppm threshold is a total-fluorine trigger, not a directly measured total-PFAS concentration. The complementary analysis shall identify and quantify the PFAS contribution within its validated scope and coverage; the analytical scope, including which polymeric PFAS are covered and how their contribution will be quantified, shall be agreed between buyer and supplier in advance, and test reports shall state the scope, recovery, limitations and limit of quantification for each determination. The quantified contribution is a partial result within the agreed analytical scope and is not a total-PFAS result. Compliance shall be established only within that agreed scope: where the laboratory cannot demonstrate adequate analytical coverage and quantification, the result shall be classified as indeterminate, further evidence is required, the product is not accepted under this requirement, and the result shall not be described as total PFAS content or accepted as evidence of compliance. Contractual acceptance within the validated scope shall not be represented as a statutory determination of total PFAS content; (d) PFHxA and its salts ≤ 25 ppb in aggregate, by PFHxA-specific analysis (PFHxA is within the EN 17681-1:2025 target list; the laboratory shall confirm the method covers it and report the limit of quantification for the PFHxA and salts determination); (e) PFHxA-related substances ≤ 1,000 ppb in aggregate, by a validated method for the defined related-substance group, with documented laboratory confirmation of coverage of the legally defined related-substance group and disclosure of the validated method’s limitations. Test reports shall identify the laboratory, the standard version and method for each requirement, and the membrane and finish chemistry by name.”

Two distinctions in that clause do real work:

1. “No intentionally added PFAS” versus “zero PFAS”. The first is a claim a supplier can stand behind; the second is a claim about trace contamination that no manufacturer can honestly guarantee. Writing the achievable claim into the contract, with the thresholds as the measurable test, avoids both greenwashing and an impossible warranty.
2. Membrane and finish named separately. A certificate that says “PFAS-free” without naming the membrane polymer and the DWR chemistry is not evidence. Name both, and require the test report to match the named chemistry.

Buyers should also decide, before ordering, which end use the garment serves. A shell that only needs rain protection can go to C0 DWR now. A workwear garment that needs oil repellency should be trialled with the silicone-hybrid or other fluoro-alternative finish on the actual fabric, with wash testing to an agreed cycle count, before bulk approval. And any non-exempt garment within the decree’s scope placed on the French market must meet the applicable three thresholds — not just a supplier declaration.

Frequently asked questions

Is PFAS banned in clothing in the EU?
Not EU-wide, not yet. France bans PFAS in consumer clothing, footwear and waterproofing agents from 1 January 2026, with measurable thresholds. The EU restricts PFHxA in clothing from 10 October 2026. A universal EU PFAS restriction is under evaluation at ECHA, with adoption currently estimated for late 2027 or 2028 and implementation not expected before 2029.

What is the difference between ePE and ePTFE membranes?
ePTFE (expanded polytetrafluoroethylene) is a fluoropolymer in the PFAS family and the traditional Gore-Tex membrane material. ePE (expanded polyethylene) is Gore’s newer alternative membrane that is not a fluoropolymer.

Can fluorine-free DWR match fluorinated DWR?
For water repellency, Prance considers its fluorine-free finish suitable for these applications, subject to validation on the intended fabric and laundering conditions — that is Prance’s assessment of water repellency on test swatches, not a guarantee of wash durability or garment-level performance. For combined water and oil repellency, Prance’s assessment is that no fluorine-free alternative matches a Teflon finish today — that is Prance’s conclusion from its own assessment and tested applications, not an industry-wide comparison of all fluorine-free finishes or constructions. Dow’s November 2026 silicone-organic hybrid finish is designed to close that gap, but buyers should verify it on their own fabric.

How do I evidence a PFAS claim for a garment?
Keep three things separate: (1) the supplier declaration — “no intentionally added PFAS”, supported by supply-chain evidence from the membrane and finish suppliers; (2) targeted analytical testing to EN 17681-1:2025 for the 25 ppb / 250 ppb thresholds, with documented laboratory confirmation of analyte coverage, polymer exclusion and any complementary method necessary, plus PFHxA-specific analysis for the 25 ppb / 1,000 ppb limits; (3) total-fluorine screening against the 50 mg/kg trigger, followed where needed by a laboratory-validated complementary analysis to establish the PFAS contribution — only where the laboratory can demonstrate adequate coverage and quantification; where it cannot, the result is indeterminate, further evidence is required, the product is not accepted under this requirement, and the result shall not be described as total PFAS content. The 50 ppm figure is a voluntary contractual total-fluorine screening criterion, not a total-PFAS measurement; compliance can only be established within the agreed analytical scope and demonstrated laboratory coverage. The statutory threshold is a total-fluorine trigger, not a directly measured total-PFAS concentration. Meeting a set of thresholds is evidence against those thresholds; it does not prove the absolute absence of PFAS, and “PFAS-free” should not be used as a shorthand for any of the three. Compliance cannot be inferred beyond the demonstrated analytical coverage: an incomplete analyte scope is indeterminate, not evidence of compliance.

Does the French ban apply to workwear?
Consumer clothing is covered from 1 January 2026. Professional clothing is covered only from 1 January 2030, and professional footwear remains outside the scope even then. Personal protective equipment within Regulation (EU) 2016/425 is exempt, as is armed-forces equipment. Check the specific product category against the decree rather than assuming — a garment marketed as “workwear” may be consumer clothing, professional clothing or PPE, and the answer changes with the category.

Will waterproof breathable fabric get more expensive?
New membranes and finishes carry development and requalification costs, and poorly matched specifications may increase the risk of returns and rework. No general price effect has been published; buyers should cost the change per style, not assume a market-wide figure.
