Lee Classics Mens 4x Blue Long Sleeve Wrinkle Resist Button Down Shirt
Wrinkle-resist treatment raises PFAS concern; no brand disclosure available.
Lee's wrinkle-resist cotton shirt likely uses durable press finish, commonly applied with PFAS. No public disclosure of treatment chemistry or testing. Cotton base is inherently lower risk than synthetic.

The full breakdown
What it's made of and why it matters
This shirt is a cotton-polyester blend treated with a durable press (wrinkle-resist) chemical finish. Durable press treatments historically rely on formaldehyde-based resins or, increasingly, alternative chemistries that may include PFAS compounds to achieve water and soil repellency alongside wrinkle resistance. The polyester component itself is stable, but the finish applied to the fabric surface is where chemical concerns arise. Blended textiles with finishing treatments can release volatile compounds, especially when new and during the first several washes.
The brand's record and disclosure
Lee (owned by Kontoor Brands) does not publicly disclose detailed information about the specific chemistry of wrinkle-resist treatments used in its basic apparel lines. The brand has not published a PFAS elimination roadmap or third-party test results for finished garments. This silence is typical for mainstream jeans and workwear manufacturers but represents a material gap in transparency compared to outdoor and premium brands that now test and certify durable press finishes as PFAS-free. No recalls or safety incidents specific to Lee wrinkle-resist products have been widely documented.
How it compares in its category
Wrinkle-resistant cotton-polyester blends are standard in affordable menswear and represent a middle ground in chemical risk. Premium brands (Arc'teryx, Patagonia) and some mid-market competitors now offer PFAS-free durable press alternatives, though at higher cost. Basic retail lines like Lee Classics have not yet shifted supply chains to PFAS-free finishes as a standard. Untreated cotton or linen shirts eliminate durable press chemistry entirely but require more ironing; synthetic or fully polyester options move the concern to antimony stabilizers and potential microfiber shedding instead.
If you buy it
Wash the shirt 2-3 times before wearing, in cool water, to rinse out loose chemical residues and reduce inhalation of volatile finishing agents. Use mild detergent; avoid fabric softeners, which can interact with the finish. Dry on low heat or air dry to prevent heat-driven release of finish compounds. Do not store unwashed in a plastic bag long-term. Replace the shirt when seams fray or the collar/cuffs soften, as this signals finish degradation and potential microfiber shedding. If you experience skin irritation or respiratory sensitivity when wearing new wrinkle-resist garments, switch to untreated cotton alternatives.
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 durable press finish
Durable press treatments on cotton-polyester blends classically use formaldehyde-based resins. Although modern treatments have reduced but not eliminated this, low-level formaldehyde release can occur, especially on unwashed new garments. Individuals with contact dermatitis or formaldehyde sensitivity may experience skin irritation.
Chemical off-gassing and volatilization
Wrinkle-resist finishes may emit volatile organic compounds (VOCs) when new and during storage. Heating (body warmth, hot water wash, dryer) accelerates volatilization. Ventilation during first use and washing in cool water reduce exposure.
Azo dyes in blue colorant
No specific safety alerts on file for Lee Classics blue colorants. Standard indigo or synthetic azo dyes used in menswear are regulated in most markets. Risk is low in finished, rinsed garments but worth confirming if you have dye sensitivity or allergy history.
Antimony in polyester component
Polyester fibers may contain trace antimony as a catalyst residue, typically at levels below regulatory concern. Direct skin contact with a finished garment poses minimal risk; concern would apply mainly to textile workers or prolonged skin exposure to raw fiber, which does not apply here.
Microplastic shedding from blend degradation
Repeated washing and wear break down the polyester fibers and finish, releasing microplastics into wastewater. This is a persistent environmental concern with all synthetic-blend textiles but does not pose direct health risk to the wearer.
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.
