How to Tell if Your Motorcycle Gear Contains PFAS (And What to Do About It)

Per- and polyfluoroalkyl substances (PFAS)—often called "forever chemicals"—are synthetic compounds historically used in motorcycle gear to provide durable water repellency (DWR). Because these chemicals do not break down in the environment or the human body, they are a concern for riders who wear treated textiles for long durations.

The bottom line: If your gear was manufactured before 2015, it likely contains long-chain C8 PFAS. While the industry is shifting toward safer alternatives, identifying your current equipment's status is the first step in managing potential exposure.

What Are PFAS and Why Do They Matter?

PFAS are a family of thousands of chemicals used to repel water, oil, and stains. In motorcycle apparel, they are the active ingredients in the DWR coatings on the outer shells of jackets, pants, and gloves.

The primary concern is C8-era chemistry. These "long-chain" PFAS are highly effective at shedding water, but they are linked to health risks, including endocrine disruption and immune system interference. Because motorcycle gear is worn for long periods and subjected to heat and friction, the risk of chemical migration—where the substance transfers from the fabric to your skin—is a valid concern.

Note: The industry is currently transitioning away from long-chain variants toward shorter-chain (C6) or entirely fluorine-free (PFC-free) alternatives. While C6 is considered less persistent than C8, it is still a fluorinated compound.

How to Identify PFAS in Your Gear

Manufacturers rarely list specific chemical treatments on care tags. Use these indicators to estimate the risk level of your gear:

The "Water Bead" Test: If your gear is several years old and water still beads up perfectly on the surface, it is treated with a synthetic DWR. This confirms the presence of a chemical treatment that is likely degrading.

Check Marketing Materials: Search the manufacturer's website or original product hangtags for terms like "PFC-Free," "Fluorine-Free," or "Eco-DWR." If the marketing materials from the time of purchase emphasized "Teflon" or "Gore-Tex" without mentioning "PFC-free," assume the gear contains traditional PFAS treatments.

If you cannot find a production date on the internal garment tag, contact customer support with your model name and serial number. Ask specifically: "Does this product use a C8 or C6 fluorocarbon-based DWR, or is it PFC-free?" Many manufacturers now publish Restricted Substance Lists on their sustainability pages.

Decision Framework: Keep, Clean, or Replace?

If you suspect your gear contains PFAS, you do not need to discard it immediately. Use this framework to manage your exposure:

• Keep and Use: If the gear is in good condition, wear it over a base layer (like a long-sleeve moisture-wicking shirt). This creates a physical barrier that significantly reduces direct skin contact. PFAS are most dangerous when ingested or inhaled, so avoid wearing the gear in a way that allows the fabric to rub against bare skin.
• Clean and Re-treat: If your gear has lost its water repellency, do not use standard household detergents, which can strip the coating and cause chemical shedding. Use a specialized, PFC-free technical wash and re-proofer. This encapsulates the old treatment and adds a safer, modern layer of protection. For older fluorinated gear, avoid machine washing when possible—washing releases PFAS particles into wastewater. Spot-clean the exterior with a damp cloth instead.
• Replace: If the gear is physically degrading—the inner lining is flaking, the fabric is thinning, or the DWR is failing despite proper cleaning—it is time to retire the item. When buying new, prioritize brands that explicitly state their commitment to PFC-free manufacturing processes.

Methodology: This guidance is based on the industry-wide phase-out of long-chain PFAS (C8) initiated by the EPA in 2006 and the subsequent adoption of shorter-chain (C6) and fluorine-free alternatives by major textile manufacturers. No public dataset exists for the chemical composition of every legacy motorcycle garment; this guide uses manufacturing dates as a proxy for chemical risk.

Understanding DWR: C8, C6, and PFC-Free

Durable Water Repellent (DWR) is the chemical coating on your motorcycle gear that forces water to bead and roll off. When DWR fails, your gear "wets out," absorbing water, becoming heavy, and losing breathability.

Historically, manufacturers used C8 chemistry (long-chain fluorocarbons) because it offered superior oil and water resistance. However, C8 contains PFOA, a persistent chemical linked to long-term health and environmental risks.

The Evolution of DWR Chemistry

The industry has largely moved away from C8 due to regulatory bans and health concerns. Here is how the three generations of DWR compare:

| DWR Type | Chemistry | Performance | Environmental Impact | | :--- | :--- | :--- | | C8 | Long-chain PFAS | Excellent | High (Persistent/Toxic) | | C6 | Short-chain PFAS | Good | Moderate (Still persistent) | | PFC-Free | Hydrocarbons/Silicone | Moderate | Low (Non-persistent) |

• C8 (Legacy): Common in gear manufactured before 2015. It is highly effective but remains in the environment and human body for years. If your gear is over a decade old, assume it uses C8.
• C6 (Transition): The current standard for many high-end touring suits. It is less toxic than C8 but still relies on PFAS chemistry. It provides reliable, long-lasting water beading.
• PFC-Free (Modern): The safest option. These use non-fluorinated compounds. They are less durable than fluorinated versions and require more frequent re-application of aftermarket treatments to maintain performance.

Decision Rules for Your Gear

Because PFC-free treatments have lower surface tension, they wear off faster than fluorinated versions. Use these rules to manage your kit:

• If you own legacy C8 gear: You do not need to discard it immediately, but avoid washing it in a way that flushes chemicals into the water supply. Use a specialized, contained cleaning process if possible.
• If you prioritize safety over convenience: Choose PFC-free gear. Accept that you must re-apply a DWR spray (such as Nikwax or other PFC-free options) at the start of every season or after heavy rain exposure.
• If you ride in extreme, multi-day rain: C6 or C8 gear will stay "dry" longer without maintenance. If you choose PFC-free for these conditions, carry a travel-sized re-proofer to maintain the DWR layer during your trip.

How to decide: If your gear stops beading water and starts soaking through within minutes of rain, the DWR has failed. Regardless of the chemistry (C6 or PFC-free), it is time to clean the garment and apply a fresh DWR treatment to restore its function.

Methodology note: This comparison is based on industry-standard chemical classifications (long-chain vs. short-chain fluorocarbons). No public, gear-specific dataset exists that lists the exact DWR chemistry for every model ever produced; check your manufacturer's technical specifications or "sustainability" page for specific product certifications.

Shopping for PFAS-Free Gear

You cannot identify PFAS by sight or smell. When buying new equipment, ignore vague marketing terms like "eco-friendly" or "green." Instead, look for these indicators:

1. Explicit "PFC-Free" labeling: Brands that have transitioned to non-fluorinated DWR will state "PFC-Free" or "PFAS-Free" in technical specifications—not just marketing copy.
2. Bluesign® Certification: A Bluesign® Approved product ensures the entire supply chain has been audited for chemical safety.
3. ZDHC Signatories: Prioritize brands committed to the Zero Discharge of Hazardous Chemicals (ZDHC) roadmap for removing hazardous substances from production.

Evaluating Manufacturer Claims

The Rule: If a brand's technical documentation does not explicitly state "PFC-free" or "fluorine-free," assume the garment uses a fluorinated DWR. If you cannot find a clear chemical policy on the manufacturer's website, contact customer support and ask: "Does this garment use a fluorinated DWR treatment?" If they cannot answer, choose a different brand.
