Brooks Brothers Men's Classic Fit Cotton Blend Dress Pants with Side-Tab
Cotton blend with no stated water or stain treatment, lower concern.
Brooks Brothers does not disclose PFAS-related treatments on this product. Cotton-dominant apparel typically has lower PFAS risk unless treated for water or stain resistance, with no such treatment claimed here.

What Brooks Brothers Men's Classic Fit Cotton is made of, ingredients and materials
Brooks Brothers Classic Fit Cotton Blend Dress Pants are primarily cotton with a synthetic blend (typically polyester) for durability and wrinkle resistance. No water-repellent, stain-resistant, or flame-retardant chemical treatment is disclosed by the brand. The cotton content reduces synthetic microplastic shedding risk versus full polyester, while the blend improves dimensional stability and reduces wrinkle-prone shrinkage, common reasons conventional cotton dress pants are treated.
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.
Formaldehyde / VOCs
Cotton-blend dress pants often use formaldehyde-based resins to improve crease retention and dimensional stability. Brooks Brothers does not disclose this treatment; it is standard in the category. Off-gassing typically subsides after 1-2 washes and poses low skin-contact risk in finished garments.
Source, ATSDR ↗Azo dyes and synthetic dye residues
Dark-colored dress pants rely on azo dyes and synthetic colorants. Some azo dyes can degrade into aromatic amines under sweat and friction; others present lower concern for this degradation pathway. No dye-safety certification is disclosed. Pre-wash reduces loose dye transfer.
Microplastic shedding from synthetic blend fibers
Polyester content sheds microfibers during wash and wear. Cotton-blend composition (vs. 100% polyester) reduces overall shedding volume. Care practices (gentle wash, cold water, lower drying heat) minimize fiber degradation and release.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Antimony in polyester component
Antimony is used as a polyester catalyst during synthetic fiber production. Modern polyester typically releases negligible antimony in finished fabric. No contamination reports exist for Brooks Brothers dress pants. Risk is theoretical and well below regulatory concern for apparel.
Heavy metals
Dress-pants buttons and zippers may contain trace metals (zinc, nickel, lead) depending on manufacturer. Brooks Brothers does not disclose supplier standards. Skin contact is minimal and indirect; no safety alerts exist for this product.

The brand's record and disclosure
Brooks Brothers does not publicly disclose chemical treatment protocols or certifications (such as OEKO-TEX or Bluesign) for this product line. The brand has not faced major chemical safety recalls or public controversies specific to dress pants. Disclosure remains minimal compared to outdoor or performance brands, though Brooks Brothers targets corporate wear where heavy chemical loads are less typical than in technical apparel.
How it compares in its category
Men's dress pants in this price/quality tier rarely carry specialized chemical finishes; Brooks Brothers' silent stance on treatment mirrors most traditional suiting brands. Premium alternatives (e.g., Hugo Boss, Banana Republic) offer similar opacity on chemical use. Brands offering certified chemical-free or OEKO-TEX dress pants exist but are less common in mainstream menswear and typically cost more.
If you buy it
Wash in cool water before first wear to reduce loose formaldehyde resins and excess dyes. Machine wash warm (not hot) on gentle cycle to minimize synthetic fiber breakdown and color bleeding. Avoid chlorine bleach and high-heat drying, which can degrade both cotton and polyester. Inspect seams and buttons annually for wear; replace or retire pants if coating on buttons degrades or seams fray, as fraying synthetic fibers may increase microplastic shedding during wear.
