Carhartt · Stain-Resistant Professional Workwear
Carhartt Men's Flame Resistant Force Rugged Flex Loose Fit Twill Plaid Shirt
Flame-resistant apparel carries PFAS risk. Carhartt provides no disclosure on treatments.
Flame-resistant and water-repellent coating-treated work shirts often use PFAS-based chemicals. Carhartt does not publicly disclose PFAS use or avoidance in this product line.

The full breakdown
What it's made of and why it matters
This shirt is cotton twill with two chemical treatments: a water-repellent coating (water-repellent coating) finish and a flame-resistant (FR) chemical applied to meet workwear safety standards. Cotton alone does not self-extinguish; FR additives (historically PFOA-based, now often different chemistries) are sprayed or bound into the fibers to prevent ignition and slow burn rate. The water-repellent coating adds water and stain resistance but is a separate concern for PFAS leaching.
The brand's record and disclosure
Carhartt does not publicly disclose the specific FR or water-repellent coating chemistry used in this garment, nor does it certify compliance with PFAS-free standards or participate in industry transparency programs (such as bluesign or OEKO-TEX). The brand has not announced phase-out commitments for PFAS in flame-resistant lines. This silence is typical for workwear manufacturers but limits buyer ability to assess actual chemical exposure risk.
How it compares in its category
Most FR workwear at this price and durability level uses conventional FR chemistry, often PFAS-containing. Competitor brands (Dickies, Wrangler FR lines) have similar disclosure gaps. High-end alternatives with certified low-chemical or PFAS-free FR finishes exist (e.g., some Nomex blends, or brands certified to OEKO-TEX Standard 100) but command higher cost and narrower fit/aesthetic range.
If you buy it
Launder separately in cold water with minimal detergent for the first 5-10 washes to reduce leaching of surface treatments. Avoid high heat drying; air dry or low heat. The FR finish is durable but degrades with repeated washing and high-temperature laundering, reducing flame resistance. Replace when FR performance is visibly compromised (fabric pilling, color fading, or loss of stiffness suggests chemical degradation). Do not dry-clean, as solvents can mobilize PFAS residues.
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.”
Flame-resistant chemical treatment (PFAS and alternatives)
Carhartt does not disclose whether this FR finish uses legacy PFAS (PFOA/PFOS alternatives), newer fluorinated or non-fluorinated FR resins, or phosphorus-based chemistries. FR workwear typically contains PFAS; skin absorption and inhalation of particulates during wear is a known pathway of exposure, especially if the coating degrades.
water-repellent coating (water-repellent coating) treatment leaching
water-repellent coating coatings on textiles can release PFAS or other water-repellent compounds during washing and body contact. No test data on this specific Carhartt product is publicly available, but migration into sweat and repeated skin contact is a recognized exposure route for water-repellent coating-treated apparel.
Formaldehyde-releasing resins in fabric finish
Formaldehyde is not typically used in flame-resistant finishes; however, low levels may be present in dyes or fabric sizing on cotton twill. No recalls or warnings specific to Carhartt FR apparel for formaldehyde exist on record.
Azo dyes and heavy metal pigments in dyes
The plaid pattern uses multiple dyes; Carhartt does not certify dye chemistry. Restricted azo dyes and heavy metal contamination are not documented in this product line, but no third-party testing or certification is publicly available to rule them out.
Particle inhalation from degraded FR coating
As FR and water-repellent coating finishes degrade through washing and wear, micro-scale particulates of the chemical coating may become airborne or settle on skin. Long-term occupational exposure to FR-treated garments has not been extensively studied in terms of chronic inhalation risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
