Dickies Men's FLEX Relaxed Fit Short Sleeve Twill Work Shirt
Basic work shirt, no PFAS-prone treatments evident.
Plain cotton twill work shirt with no disclosed water-resistant or stain-resistant finishes. Dickies has not made PFAS claims; inherent cotton material poses lower PFAS concern than treated textiles.

The full breakdown
What it's made of and why it matters
This shirt is 100% cotton twill, a tightly woven fabric commonly used in work apparel because it resists tearing and abrasion. Cotton itself carries minimal inherent chemical risk compared to synthetics, though the manufacturing process (dyeing, finishing, and any water-resistance treatments) introduces potential exposure points. Twill's durability means the garment is less likely to shed microfibers or degrade into problematic particles during normal wear and washing. The absence of synthetic blends removes antimony contamination risk (common in polyester) and reduces likelihood of problematic flame-retardant coatings.
The brand's record and disclosure
Dickies does not publicly disclose detailed chemical composition or finish treatments on this product line, which is typical for mainstream workwear brands but limits transparency on dyes, resins, or water-repellent agents used. The company has no known recalls related to chemical hazards in basic twill work shirts. Dickies does not independently certify products to bluesign, GOTS, or similar textile safety standards, relying instead on baseline US/imported-goods compliance. No established controversies exist regarding formaldehyde releasers or azo dyes in their standard work shirt offerings.
How it compares in its category
Dickies FLEX work shirts occupy the mid-market workwear segment and have a reputation for durability and minimal chemical hazard reporting compared to fast-fashion cotton alternatives. Most competitors at this price point (Carhartt, Walls, Rugged Trails) use identical or similar 100% cotton twill without additional safety certification, so this product is broadly representative rather than exceptional. The lack of PFAS-prone water-repellent finishes is a neutral-to-positive feature; many premium work shirts add durable water-resistance (water-repellent coating) coatings that may contain PFAS, which this shirt apparently does not. Overall, this is a lower-risk garment within standard workwear category norms.
If you buy it
Wash the shirt in cool water before first wear to reduce residual dyes and any processing chemicals. Standard laundry care (40-60 degrees Celsius max) is safe; avoid chlorine bleach, which can interact with any residual finishing resins. Replace when seams fray, collar/cuff elastic fails, or fabric tears, as cotton twill durability typically supports 2-3 years of regular work use. No special storage precautions needed; cotton does not off-gas volatile organic compounds over time like some synthetics.
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.”
Formaldehyde releasers in resin finishes
No water-repellent or wrinkle-resistant coating is described or evident in Dickies FLEX twill work shirts. Unfinished 100% cotton twill carries no established formaldehyde risk.
Azo dyes
Cotton twill work shirts are typically dyed with conventional reactive or vat dyes; Dickies does not specify banned azo dyes (such as those releasing carcinogenic amines) but does not exclude them either. Risk is low for skin contact during wear but possible during manufacture. Washing reduces loose dye residue significantly.
Antimony in synthetic fibers
100% cotton composition eliminates antimony risk, which is specific to polyester and other synthetics used as catalysts in fiber production.
Flame retardant treatments
Dickies work shirts are not marketed as flame-resistant and are not treated with halogenated or phosphorus-based flame retardants. Cotton twill meets general flammability standards without chemical additives.
Heavy metal dyes and pigments
Pigment-based dyes in some cotton garments may contain trace lead, cadmium, or chromium, especially in darker colors. No testing data is publicly available for this specific product line. Risk is minimal for typical skin contact but requires awareness during care (avoid ingestion, especially for children).
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
