Gap Men's Modern Khakis In Athletic Taper
Lower concern. Untreated cotton blend has minimal PFAS risk.
Gap's khakis are standard cotton-blend twill with no waterproof or stain-resistant finishes listed. No PFAS disclosure from brand, but untreated woven apparel carries lower inherent risk than water-repellent coating treated textiles.

The full breakdown
What it's made of and why it matters
Gap's Modern Khakis are cotton-blend woven twill, typically 98% cotton / 2% spandex or similar elastane mix. The cotton dominates the fiber profile, reducing chemical treatment burden compared to synthetic-heavy blends. Twill weave (diagonal rib pattern) is inherently durable and requires fewer finishing chemicals than plain weaves to achieve wrinkle resistance or softness. The small spandex component improves stretch and recovery without triggering high-risk processes like vinyl or polyurethane coating.
The brand's record and disclosure
Gap Inc. has not published detailed chemical disclosure or restricted substance lists specific to this product line as of public record. The company is not known for major formal chemical certifications (e.g., bluesign, GOTS, Cradle to Cradle) on standard basics like khakis. Gap has faced scrutiny on labor and environmental practices but no established recalls or safety alerts on formaldehyde, azo dyes, or heavy metals in their men's basics. Absence of disclosure does not indicate absence of hazard, but reflects industry-standard opacity for mid-market casual wear.
How it compares in its category
Cotton-blend casual pants sit in the lower-risk tier for apparel hazards relative to synthetic activewear, dyed denim, or flame-retardant treated garments. Khakis typically undergo fewer aggressive dye cycles than darker pants, reducing azo dye and heavy metal pigment exposure. Gap's mainstream positioning and scale mean higher likelihood of basic regulatory compliance (no lead, cadmium limits met in most markets) compared to unbranded fast-fashion imports, though certification gaps remain.
If you buy it
Wash before first wear to reduce residual formaldehyde resins and loose dyes. Cold water and mild detergent minimize color bleeding and fiber stress. Spandex content (typically 2%) will degrade after 50-100 wash cycles; expect gradual loss of stretch and shape retention. Store dry and avoid prolonged heat (tumble dry low or air dry) to slow elastane breakdown. No special precautions needed beyond standard garment care.
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 (finish treatments)
Cotton twill may receive formaldehyde-based wrinkle or shrink-control finishes common in casual pants manufacturing. No specific testing on Gap khakis is on record. Pre-wash is standard mitigation.
Azo dyes and heavy metal pigments
Khaki (tan/neutral) colorants typically carry lower azo dye burden than deep reds, blacks, or blues. Compliance with lead/cadmium limits in major markets is likely but unverified by public testing.
Antimony in polyester (blend component risk)
Spandex (polyurethane elastomer) is the secondary fiber, not polyester; antimony is not a typical concern in spandex. Risk from this hazard is minimal.
Flame retardants
Untreated cotton-blend casual pants are not typically flame-treated unless marketed as sleepwear or workwear. No evidence of flame retardant application on standard Gap khakis.
Elastane (spandex) degradation and microfiber shedding
The 2% spandex component will degrade with washing and UV exposure, releasing microfibers. This is inherent to stretch blends and not unique to Gap, but a practical durability and environmental consideration.
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.
