If your product line includes anything with a water-resistant or wind-resistant finish — running jackets, wind shells, water-repellent leggings, technical bags — a PFAS-free sourcing conversation is no longer optional for several major markets. California’s textile PFAS law is already partly in force, several more US states have similar bills moving through 2026 sessions, and the EU is working through its own broader PFAS restriction. None of this is exotic sustainability marketing anymore; it is becoming a hard compliance requirement tied to specific dates.
General sourcing guidance as of July 2026, not legal or regulatory advice. PFAS rules are state- and country-specific and are changing quickly — confirm current requirements for your exact product category with your compliance counsel or testing lab before you finalize labeling or claims.
Why activewear specifically is exposed
PFAS (“forever chemicals”) shows up in apparel mainly through durable water repellent (DWR) finishes — the coating that makes a shell jacket bead water, or gives a legging or bag a splash-resistant surface. Traditional DWR chemistry (long-chain C8, and to a lesser extent C6, fluorocarbons) is exactly what these bans target. That makes technical and outdoor-adjacent activewear — wind shells, running jackets, water-resistant packable layers, some swimwear and bag trims — the categories with the most direct exposure, more so than plain cotton tees or basic leggings with no water-repellent finish.
What’s actually changing in 2026
| Measure | Status as of mid-2026 | What it covers |
|---|---|---|
| California AB 1817 | 100 ppm limit in force since Jan 2025; drops to 50 ppm 1 Jan 2027 | Intentionally added PFAS in general textiles; outdoor severe-wet-weather apparel exempted until 2028 but must be labeled if it contains PFAS |
| Other US states (e.g. NY, WA and others with similar bills) | Mixed — some passed, some pending in 2026 sessions | Broadly similar intentionally-added-PFAS thresholds; exact scope and dates vary by state |
| EU-wide PFAS restriction (REACH) | Proposal under review; no final apparel-specific date confirmed | Would restrict PFAS use much more broadly across products sold in the EU if adopted as proposed |
| UK | Watching EU/US developments; no equivalent apparel-specific ban finalized as of mid-2026 | Not yet a discrete UK apparel PFAS rule |
Treat every date and threshold in that table as indicative — state legislation and EU rulemaking both move on their own timelines, and amendments are common. The trend line, not any single number, is the part to plan around: PFAS-free DWR is heading toward becoming the default expectation, not a premium add-on.
What to ask your factory before you place a PO
- Ask what DWR chemistry is actually used — not just “is it eco-friendly,” but the specific finish family (fluorocarbon-based vs. PFAS-free hydrocarbon/silicone alternatives). A factory that can answer this precisely, with a spec sheet, is one that has already done the work.
- Ask for a test report on the finished fabric, not just a general facility certificate. PFAS testing is finish-specific — a factory’s OEKO-TEX or bluesign status is a good signal but is not a substitute for a report on the exact fabric and finish going into your order.
- Check labeling requirements for your target state or market before finalizing hangtags — some jurisdictions require an explicit PFAS content disclosure if the finish still contains it during the transition window.
- Ask about performance trade-offs early in development. PFAS-free DWR has closed most of the performance gap with fluorocarbon finishes for typical activewear use (light rain, wind, splash resistance), but very high-durability or extreme-weather claims may still need testing to confirm they hold up over the garment’s expected wash cycles.
Where this fits with certifications you already ask for
If you already require bluesign or OEKO-TEX STANDARD 100 from your suppliers, you have a head start — both systems restrict or screen for a number of PFAS substances as part of their existing scope. Neither certificate is a guaranteed “PFAS-free” claim on its own, though, so pair it with a direct, finish-specific question to your factory rather than assuming the certificate covers it. Our eco-certifications guide breaks down exactly what OEKO-TEX, bluesign and GRS each do and don’t certify, and our social-compliance certifications guide covers the audit side (BSCI, WRAP, Sedex) that usually comes up alongside these chemical-safety questions.
Building it into your next sourcing cycle
For brands developing wind shells, water-resistant leggings, or technical outerwear for private label or custom leggings programs, the practical move is to bake the DWR chemistry question into your tech pack and supplier qualification process now — before a state deadline forces a rushed fabric change mid-production. A factory that is already running PFAS-free finishes at scale, and can hand you the paperwork to prove it, removes a compliance risk you would otherwise be carrying alone.
