Calvin Klein Men's Hi-Stretch Tech 5-Pocket Slim Pants
Lower concern; standard casual pants with no PFAS-risk treatments identified.
Hi-Stretch Tech pants appear to be basic cotton-blend construction without water repellent or stain-resistant finishes. No PFAS disclosures found, typical for non-performance casual wear.

The full breakdown
What it's made of and why it matters
This product is a cotton and elastane blend, a very common pairing in stretch casual trousers. Cotton is a natural fiber with minimal chemical hazard risk when untreated; elastane (spandex) is a synthetic polymer that adds stretch without requiring problematic additives. The "Hi-Stretch Tech" designation refers to the elastane content, which typically ranges 2-8% by weight. This material combination does not require flame retardants, heavy chemical finishes, or water-repellent coatings that would introduce hazard concerns.
The brand's record and disclosure
Calvin Klein is owned by PVH Corp, a large apparel conglomerate with public sustainability commitments but limited product-level chemical transparency for most items. The brand has not published specific restricted substance lists or certifications for basic casual pants, and does not widely disclose manufacturing chemical controls for non-performance-wear categories. No major chemical-safety recalls or controversies specific to Calvin Klein basic trousers are on public record. The brand's silence on PFAS reflects industry-wide opacity rather than known non-use.
How it compares in its category
Cotton-elastane 5-pocket slim pants are a commodity product category with minimal differentiation in chemical hazard profile. Most mainstream brands (Gap, J.Crew, Uniqlo, Banana Republic) use identical or near-identical material compositions. Higher-priced alternatives rarely offer additional safety benefit unless third-party certified (GOTS, OEKO-TEX, bluesign). Lower-priced alternatives may use higher elastane percentages or recycled synthetics, but hazard levels remain comparable for untreated casual wear.
If you buy it
Wash in cool to warm water before first wear to remove residual dyes and finishes. Air dry or low-heat tumble drying; high heat can degrade elastane fibers and potentially increase microfiber shed. Inspect seams and hems yearly for pilling or degradation, as these trigger fiber shedding rather than chemical release. Standard detergent is sufficient; no special care needed beyond normal garment maintenance.
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 (durable-press finish)
No performance finish typical of this product category. Standard cotton-elastane casual wear does not employ formaldehyde-based crease-retention or wrinkle-resistance treatments.
Azo dyes (carcinogenic color additives)
Black, navy, and darker colorways may use azo dyes, which are permitted in most markets but restricted in EU. Calvin Klein does not publicly commit to azo-free dyeing for basic apparel; no testing data available for this specific product.
Antimony in polyester
This product is cotton-elastane, not polyester. Antimony is not a concern for this material composition.
Microplastic shedding from elastane
Elastane fibers shed progressively with wear and washing, releasing microplastics into water and accumulating in laundering waste. This is inherent to all elastane garments; Calvin Klein products offer no differentiation. Washing in cold water and air drying may reduce shed rate marginally.
Heavy metals in dyes and pigments
No public records of heavy-metal contamination in Calvin Klein casual pants. Industry best-practice testing is not disclosed, but modern dye suppliers to major brands routinely screen for lead and cadmium.
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.
