CALVIN KLEIN TRIM FIT NON-IRON PANT, 40 x 30 / Charcoal
Non-iron finishes often contain PFAS. Skip or seek confirmation from Calvin Klein.
Calvin Klein does not disclose PFAS use in this non-iron pant. Non-iron and stain-resistant finishes commonly use PFAS chemistry, and brand silence on treatment details raises concern.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Formaldehyde / VOCs
Some non-iron finishes still use formaldehyde-releasing resins, though this has become less common. If present, small amounts may off-gas during first washes or wear, with risk higher if finish is scratched or degraded. No public test data for this specific Calvin Klein product.
Source, ATSDR ↗Finish coating degradation and microfiber shedding
Non-iron finishes degrade with age and repeated hot washing, creating flaking or shedding of treated fibers. This is cosmetic and functional (loss of non-iron properties) rather than acutely toxic, but represents potential release of finish chemicals into wash water and environment.
Residual chemicals from non-iron finish manufacturing
Manufacturing and finishing processes may leave trace amounts of uncrosslinked resins or solvent residues. First wash typically removes most residue, but complete clearance is not guaranteed and varies by finishing mill practices, which are not disclosed.
What’s reassuring
Azo dyes in charcoal colorant
Charcoal gray typically uses iron oxide or carbon-based pigments rather than azo dyes, so risk is low. Calvin Klein is not known for azo dye violations in recent years. Standard GOTS or Oeko-Tex certification would rule this out, though not listed for this product.
Antimony in polyester blending agent
Antimony is a heavy metal catalyst used in polyester production. Since this is primarily cotton, antimony exposure risk is minimal unless polyester content is very high; material composition not fully specified here. Industry use of antimony has declined due to regulations in EU and some US states.
The full breakdown
What it's made of and why it matters
This pant is a cotton blend with a chemical non-iron or stain-resistant finish applied to the fabric. Non-iron finishes (also called durable-press) typically use formaldehyde-based resins or, increasingly, PFAS-based water and stain repellents to cross-link fibers and reduce wrinkles. The finish is permanent but can degrade with repeated washing and heat, potentially releasing residual chemicals or creating microfiber shedding over time.
The brand's record and disclosure
Calvin Klein has not published a detailed PFAS elimination roadmap or third-party testing results for this product line. The brand does not explicitly disclose whether non-iron finishes use PFAS-based chemistry or fluorine-free alternatives. This silence on finish chemistry is typical across mid-market apparel brands and reflects the industry norm of treating finish formulations as proprietary.
How it compares in its category
Non-iron dress pants are ubiquitous and most major brands (Dockers, Brooks Brothers, Banana Republic) use similar finish technologies without public disclosure. Untreated cotton or linen alternatives exist but are less stain-resistant and require regular ironing. This product's risk profile is average for its category, not an outlier, meaning the hazard is systemic rather than brand-specific negligence.
If you buy it
Wash in cool or warm water (not hot) to preserve the finish and minimize any residual chemical leaching. Air-dry or tumble-dry on low heat; high heat can degrade the finish and release fumes. Replace after 2-3 years of regular wear, as finish degradation accelerates with age. Before purchase, contact Calvin Klein customer service to ask whether this specific product uses PFOA, PFOS, or other long-chain PFAS in its non-iron treatment.
