Calvin Klein Men's Slim-Fit Knit Blazer
Lower concern. Knit blazer unlikely to contain PFAS treatments.
A knit blazer typically uses untreated cotton or cotton-polyester without water-repellent coatings. Calvin Klein has not disclosed PFAS practices. No known issues reported.

The full breakdown
What it's made of and why it matters
Calvin Klein slim-fit knit blazers are typically cotton-polyester blends (often 55-60% cotton, 40-45% polyester) engineered for stretch and wrinkle recovery. The polyester component is treated with synthetic dyes and often finished with formaldehyde-based resins to improve shape retention and reduce wrinkles. Knit construction (versus woven) means tighter fabric integration, which can trap finish residues longer before washing. Cotton's natural fiber properties reduce reliance on chemical coatings compared to synthetic-heavy alternatives.
The brand's record and disclosure
Calvin Klein (Tapestry Inc. parent) does not publicly disclose detailed chemical composition or restrictive substance testing for individual pieces, and maintains no third-party certifications (Oeko-Tex, GOTS) on record for this product line. The brand has faced no major recalls or public safety controversies tied to formaldehyde, azo dyes, or heavy metals in apparel. Tapestry's corporate sustainability reporting mentions general compliance with chemical standards but lacks product-level transparency specific to knit blazers.
How it compares in its category
Cotton-polyester blends are the category norm for professional knit blazers; this product sits at mainstream risk level. Premium competitors (Loro Piana, Brunello Cucinelli) often certify higher organic/low-chemical content; fast-fashion alternatives (H&M, Zara) carry similar or slightly higher risk from cost-driven finishing shortcuts. Calvin Klein's mid-market positioning means standard chemical finishing typical of the segment, without premium certification but also without documented corner-cutting.
If you buy it
Wash before first wear in cool water to reduce residual formaldehyde and loose dyes. Use neutral pH detergent and avoid high heat (air dry preferred) to preserve polyester integrity and minimize resin off-gassing. Inspect stitching and knit structure annually; pilling or seam separation may indicate coating breakdown. Store in breathable garment bags away from direct sunlight to slow dye fading and oxidative degradation of polyester fibers.
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-based finish resins
Cotton-polyester blends in blazers routinely use formaldehyde-based cross-linking resins for wrinkle and shape recovery. Residual formaldehyde typically off-gases within first few laundering cycles; risk is low in finished garments but real in unwashed stock.
Azo dyes and heavy metal mordants
Dark knit blazers (navy, black, charcoal) may use azo dyes with heavy metal (chromium, lead) mordants for colorfastness. No specific testing on record for Calvin Klein blazers; risk is category-standard and mitigated by prewashing.
Antimony in polyester fiber
Antimony trioxide is a common polyester catalyst; finished blazers retain negligible quantities in bound fiber. No public record of leaching or dermal concern from apparel-weight polyester garments.
Synthetic dye allergens and irritation
Individuals with sensitive skin or dye allergies may experience contact dermatitis from reactive dyes, particularly in areas of friction (neck, underarms). Risk is person-dependent, not product-specific, but prewashing reduces incidence.
Microfiber shedding from polyester blend
Knit blazers do not shed microfibers into skin significantly during wear (unlike fleece or technical textiles). Washing releases minor synthetic fibers into wastewater, a laundering ecosystem concern rather than wearer safety hazard.
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.
