What Ralph Lauren Men's Slim Fit Dress Pants is made of, ingredients and materials
These pants are 100% wool with a houndstooth weave and no disclosed water-resistant or wrinkle-resistant chemical finish. Wool fiber itself is protein-based and does not leach problematic chemicals under normal wear. The houndstooth pattern is created through weaving structure, not chemical treatment. Any dyes used in wool production are subject to EU and US textile regulations, though specific dye chemistry is not disclosed by the brand.
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.
Azo dyes and synthetic dye residues
Houndstooth pattern requires dyes in wool production; specific dye chemistry is not disclosed. EU regulations prohibit certain restricted azo dyes, but non-restricted azo dyes may be used. Residual dye is unlikely to transfer significantly to skin under normal wear but may bleed slightly in first wash.
Formaldehyde / VOCs
Wool garments may undergo formaldehyde-based treatments during manufacturing or storage as a mold/insect preventative. No finish is stated, but trace residues may be present. First wash will remove most volatile residues.

Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
No wrinkle-resistant finish is disclosed on this product, so formaldehyde releasers are not expected. If finish is present but undisclosed, residual formaldehyde may off-gas slightly during first wash cycles and storage.
Source, ATSDR ↗Lead
No analytical testing is publicly available for this specific product. Wool dyes are generally lower-metal-risk than ceramics or pigments, and US and EU textile imports are subject to heavy metal limits, though enforcement variability exists.
Source, ATSDR ↗Fragrance allergens or antimicrobial treatments
No antimicrobial or fragrance additives are disclosed. Risk is low unless garment has been treated post-manufacture with sprays or storage additives, which is not standard for this price tier.
How is this PFAS grade calculated?
The brand's record and disclosure
Polo Ralph Lauren does not publicly disclose detailed chemical compositions, finishes, or third-party certifications (such as Oeko-Tex or Bluesign) for this product line. The brand has not faced major public recalls or scandals specific to dress pants chemical safety. Ralph Lauren's parent company has faced scrutiny over transparency in supply chain practices, but no established toxicological incidents are on record for wool dress pants from this brand.
How it compares in its category
Wrinkle-free or permanent-press wool dress pants often rely on formaldehyde-releasing resins or other durable-press finishes to reduce wrinkling. This product's lack of a stated finish is atypical for the category and advantageous from a chemical perspective. Most competitors in premium menswear disclose similar or less information; Ralph Lauren sits at the category median for transparency.
If you buy it
Wash in cool water with mild detergent and air dry to preserve the wool and avoid releasing any residual dyes. Do not use high heat (dryer, iron above low setting) as this can damage fiber and potentially volatilize trace finishes if present. Inspect the garment after 12-24 months for pilling or felting, which signals fiber degradation but not chemical hazard. Store in a cool, dry place away from direct sunlight to prevent fading and mold growth.
