Carhartt Men's Newcastle Shirt Jac
Carhartt does not disclose PFAS in water-repellent coating treatments; moderate concern.
Carhartt's Newcastle shirt jac has water-repellent coating water resistance but the brand provides no PFAS information. Many workwear water-repellent coating finishes use PFAS; Carhartt remains silent on composition.

The full breakdown
What it's made of and why it matters
The Newcastle Shirt Jac is a cotton-polyester blend (typical 60/40 or similar ratio) with a water-repellent coating (water-repellent coating) finish applied to the outer surface. water-repellent coating coatings are the primary chemical concern in this product class, as they historically relied on long-chain PFAS compounds to achieve water resistance. The cotton base is low-risk; the poly component itself is inert, but the finishing treatment is where chemical exposure occurs during wear and washing.
The brand's record and disclosure
Carhartt has not published ingredient lists or third-party certifications for water-repellent coating treatments on their workwear lines, and does not publicly commit to PFAS-free standards. The brand markets durability and function over chemical transparency, which is typical of heritage workwear companies but leaves consumers without confirmation of safer alternatives. No recalls or safety violations specific to Carhartt garments have been widely reported, but the lack of transparency is itself a red flag for a product with known chemical exposure pathways.
How it compares in its category
Most mainstream workwear brands (Carhartt, Dickies, Walls) remain non-transparent on water-repellent coating chemistry. Competitors like Patagonia and Arc'teryx actively market PFAS-free or PFOA-free treatments as selling points. For a utilitarian shirt jac at this price point, Carhartt's opacity is worse than premium outdoor brands but typical for the workwear segment, meaning you are trading transparency for cost and durability reputation.
If you buy it
Minimize skin contact with the water-repellent coating-coated outer layer during the first few wears, as fresh finishes may shed slightly. Wash separately from other garments the first time to contain any coating particles. Avoid high-heat drying, as heat can release volatile compounds from the finish; air dry instead. Replace the water-repellent coating every 2-3 years with a PFAS-free aftermarket treatment if the product remains in use; never re-treat with standard commercial water-repellent coating sprays without confirming they are PFAS-free.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
PFAS in water-repellent coating
Carhartt does not disclose whether this jac uses legacy long-chain PFAS, short-chain alternatives, or newer non-PFAS water-repellent coating chemistry. Industry data shows most heritage workwear brands still use PFAS-based finishes; Carhartt's silence suggests possible PFAS presence.
Formaldehyde resins in textile finishing
Cotton-poly blends often receive formaldehyde-based wrinkle-resist or crease-set treatments. Carhartt does not list or certify against this; the risk is low but not eliminated, especially if the garment underwent heavy finishing for water-repellent coating application.
Azo dyes
Carhartt's brown and earth-tone colorways are historically produced with safer non-azo dyes due to the workwear heritage and North American manufacturing base, but no public commitment or testing data confirms this for all SKUs.
Coating degradation and migration during use
water-repellent coating finishes degrade with repeated washing and wear. As the coating breaks down, any PFAS or other finish compounds may leach into sweat, soil, or wash water. Frequency of use and washing directly affects exposure.
Microfiber shedding from synthetic component
The polyester portion will shed microfibers during washing and wear, contributing to environmental PFAS transport if the water-repellent coating is PFAS-based. This is not a direct health hazard but a secondary exposure pathway.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
