Spiewak S366V VizGuard Mesh-Lined Raincoat
Raincoat with unknown waterproof coating. Skip until Spiewak discloses PFAS status.
Spiewak does not publicly disclose PFAS use or absence in this raincoat's waterproof treatment. Standard water-repellent coating finishes often contain PFAS, but no lab data or brand statement available to confirm.

Material
polyester mesh with water-repellent coating waterproof coating
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Formaldehyde / VOCs
Polyester textiles sometimes receive formaldehyde-based resin treatments for wrinkle resistance or dye fixation. Spiewak does not disclose finishing chemistry, so presence cannot be ruled out, though modern brands increasingly phase these out.
Source: ATSDR ↗Azo dyes in polyester coloring
The mesh polyester outer shell may be dyed with azo dyes, which can release carcinogenic amines under certain conditions (sweat, heat, UV). No independent testing of this specific model is on record; risk depends on dye supplier standards.
water-repellent coating degradation and unknown leachables
water-repellent coating finishes degrade with wear and laundering. If the coating is long-chain PFAS-based, migration into skin sweat or environmental runoff is possible over the jacket's lifetime. Short-chain alternatives have lower bioaccumulation risk but still lack long-term human health data.
Antimony in polyester fiber
Polyester production sometimes uses antimony trioxide as a catalyst. Finished fiber typically binds antimony tightly, but wear and washing can theoretically release trace amounts. Industry standard testing for consumer exposure is limited.
The full breakdown
What it's made of and why it matters
The S366V uses polyester mesh with a water-repellent coating (water-repellent coating) finish applied to the outer layer. water-repellent coating coatings on rainwear historically relied on long-chain PFAS (PFAS "forever chemicals") to achieve water shedding, though some manufacturers have shifted to shorter-chain or non-fluorinated alternatives in recent years. Spiewak has not publicly disclosed which chemistry they use on this model. Polyester itself is chemically stable once manufactured, but the finish applied to it is the concern here.
The brand's record and disclosure
Spiewak, a heritage US workwear and outerwear brand, has not published material safety disclosures, PFAS phase-out timelines, or ingredient transparency statements that are available to consumers. The company does not appear on lists of brands committing to PFAS-free water-repellent coating alternatives (such as those tracked by Safer Chemicals, Healthy Families). Without direct communication from Spiewak, the chemical identity of the waterproof coating remains opaque.
How it compares in its category
Many mainstream raincoat makers (Patagonia, Arc'teryx, some Outdoor Research lines) now disclose PFAS-free or low-PFAS water-repellent coating options and publish supply chain transparency. Spiewak's silence on this standard puts the S366V at a transparency disadvantage. For the price point, competitors with verified lower-risk or disclosed coatings are readily available.
If you buy it
Avoid machine washing on high heat or dry cleaning, which can degrade the water-repellent coating finish and potentially mobilize coat chemicals. Hand wash in cool water with mild detergent if needed, or spot clean. Do not tumble dry; air dry flat or hang. Replace the jacket if the water-repellent finish visibly degrades or beads poorly, as re-treatments are often unavailable and the original coating chemistry cannot be verified before reapplication.
