Calvin Klein One-Button Suit Jacket
Wool suit jacket, lower concern. No water-repellent coating finish disclosed.
Calvin Klein suit jackets are typically wool or wool blends without advertised water-resistant finishes. No PFAS claims or third-party verification available; standard tailored suiting carries lower PFAS risk than treated performance fabrics.

The full breakdown
What it's made of and why it matters
This jacket is a wool blend, likely 50-80% wool with polyester added for durability and wrinkle resistance. The polyester lining is a synthetic polymer that does not inherently release volatile chemicals at room temperature. Wool itself is protein-based and generally stable; however, both the wool and any synthetic fibers may have been treated with formaldehyde-based resins during manufacture to improve wrinkle resistance or shape retention. Polyester can also contain trace antimony (a metal catalyst used in polyester synthesis), though migration into skin contact is minimal.
The brand's record and disclosure
Calvin Klein does not publicly disclose detailed chemical testing or certifications (such as OEKO-TEX or GOTS) for individual suit jackets on their website or product pages. The brand has not faced major recalls or documented campaigns regarding formaldehyde or heavy metals in tailored clothing. As a mass-market luxury brand owned by PVH Corp, Calvin Klein operates under general apparel industry standards but does not advertise independent third-party verification of chemical limits.
How it compares in its category
Wool-blend suiting is mid-range for chemical risk in tailored menswear. It avoids the higher formaldehyde finishes sometimes used in 100% synthetic blazers and the potential for heavier dye loads in darker wools. Competitors in the same price tier (J.Crew, Banana Republic, Hugo Boss) typically apply similar finish chemistries with minimal public disclosure. Certified organic or low-impact wool alternatives (e.g., from specialized mills) would lower formaldehyde and pesticide risk, but are rarer in this market segment.
If you buy it
Wash or air the jacket before extended wear to off-gas residual formaldehyde, which is volatile and decreases over weeks. Dry clean according to label instructions; avoid home laundering unless the label permits it, as repeated home washing does not meaningfully reduce chemical residues and can damage wool. Check the interior lining periodically for pilling or separation, which would indicate degradation but poses no chemical hazard. Storage in a breathable garment bag rather than plastic reduces moisture trapping that might promote microbial growth.
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 resins in finishing
Wool-blend suiting commonly receives formaldehyde-based wrinkle-resist treatments during manufacture. No specific test data for this Calvin Klein model is available; baseline industry prevalence suggests exposure is low after initial off-gassing but possible if the jacket is unwashed at purchase.
Azo dyes and heavy metals in colorants
No documented azo dye violations or heavy metal contamination in Calvin Klein tailored apparel. Wool naturally accepts dyes well, reducing need for aggressive chemical fixing; however, formal testing of this specific jacket has not been published.
Antimony in polyester lining
Polyester linings may contain trace antimony (used as a catalyst in polyester synthesis). Migration to skin is negligible under normal wear, but linings in direct contact with sweat may pose minimal exposure if antimony levels are elevated. Not documented as a concern for Calvin Klein products.
Flame retardants in lining or finishes
Wool and polyester blazer linings are not typically treated with added flame retardants in menswear suiting, as regulatory triggers (children's sleepwear, upholstery) do not apply. No records of flame retardant use in Calvin Klein tailored jackets.
Colorant allergies and fragrance in finishing sprays
Individuals with contact dermatitis to azo dyes, formaldehyde, or fragrances in fabric finishing may react to the jacket during or shortly after purchase. Washing before wear typically mitigates this risk. No specific allergen disclosures are available for this product.
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.
