Carhartt Men's Loose Fit Midweight Chambray Short Sleeve Shirt
Lower concern. Plain cotton shirt with no water-repellent coating or stain treatment disclosed.
Chambray shirt is primarily cotton with no water-resistant or stain-resistant finish mentioned. Carhartt makes no PFAS claims, but untreated cotton carries minimal PFAS risk.

The full breakdown
What it's made of and why it matters
This shirt is 100% cotton chambray, a plainwoven fabric with no stated chemical finishes or coatings. Chambray is structurally similar to denim but lighter, using dyed warp threads over white weft, meaning color comes from yarn dyeing rather than surface treatment. The absence of a stated water-repellent coating (water-repellent coating), stain guard, or flame retardant finish means the fabric carries only the chemical risks inherent to standard textile dyeing and processing, not secondary applied coatings.
The brand's record and disclosure
Carhartt publishes minimal chemical transparency on individual garments; most product listings do not detail dye classes, finishing chemicals, or third-party testing. The brand has not pursued formal certifications like OEKO-TEX or Bluesign on most workwear lines. No public recalls or substantive safety controversies are on record for standard Carhartt cotton shirting. The silent PFAS stance reflects the broader workwear industry's limited disclosure; Carhartt has not committed to eliminating PFAS from non-water-repellent coating garments.
How it compares in its category
Basic cotton workwear shirts are among the lowest-risk garment categories because they lack technical finishes that typically introduce hazardous chemistries (flame retardants, PFAS water repellents, antimicrobial agents). This loose-fit chambray is standard construction; it sits below performance or outdoor-branded shirts that often apply multiple chemical treatments. Compared to treated chinos, water-resistant jackets, or flame-resistant workwear, a plain cotton chambray carries markedly reduced chemical exposure risk.
If you buy it
Wash the shirt once in warm water before wearing to reduce residual processing chemicals and loose dyes. Use standard laundry detergent; no special care is required for untreated cotton. Inspect seams and collar stitching for durability after 10-15 washes; loose-fit workwear typically outlasts fitted garments due to lower stress on fabric. Discard if elastic or button attachment fails or if the fabric develops persistent pilling; these signals replacement rather than repair.
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.”
Azo dyes and heavy metal residue
Chambray warp typically uses reactive or acid dyes; standard industry practice does not exclude azo dyes or heavy metal mordants (copper, chromium) in the dyeing process. No testing data or restricted substance list commitment disclosed by Carhartt for this product line.
Formaldehyde in resins or finishes
100% cotton without stated chemical finishing is unlikely to contain formaldehyde-releasing resins (wrinkle-resistance or stiffness treatments are not mentioned). Standard cotton chambray is not typically treated with formaldehyde, but residual trace amounts from dye-bath chemistry are theoretically possible.
Residual chemicals from cotton processing
Raw cotton is conventionally grown and may retain pesticide residues; bleaching and mercerization (common for chambray) use chlorine or caustic soda. No organic certification stated. First wash will remove much surface-level processing chemical residue.
Antimony in polyester blends or thread
Product is stated as 100% cotton; no polyester detected. Stitching thread composition is not disclosed, but standard cotton-blend or all-polyester thread used in workwear may contain antimony catalyst residue if not certified (rare concern but not ruled out).
Allergens in dyes and finishes
Reactive dyes and residual dye intermediates can trigger contact dermatitis or respiratory sensitivity in sensitive individuals. First wash and normal wear duration typically reduce this risk; no fragrance or chemical finish is stated to amplify allergen load.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
