Old Navy Women's Stevie Straight Pants
Lower concern. Standard pants unlikely to contain PFAS.
These cotton blend pants have no water or stain resistant treatments disclosed by Old Navy. Basic apparel materials without special finishes typically carry lower PFAS risk.

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
Old Navy does not disclose dye sourcing or restricted substance screening. If the Stevie Straight Pants contain darker colors (navy, black, dark gray), azo dyes are a common commercial choice. Risk is low in finished garment if dyes are well-fixed, but the absence of third-party testing or certification prevents definitive confirmation.
Antimony in polyester/spandex elastane
Spandex (elastane) can contain antimony as a catalyst residue from synthesis. The 2% spandex content in these pants is small, and direct skin contact is indirect (mostly under waistband and seams). No specific recall or public data exists for Old Navy spandex-blend pants, but the hazard class is recognized in the textile industry.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
No public recalls or testing data indicate formaldehyde-releasing finishes in Old Navy cotton-blend pants. Standard cotton weaves typically use minimal to no durable-press chemistry; any residual formaldehyde from manufacturing would likely offgas during initial wash cycles.
Source, ATSDR ↗Heavy metals
No recalls or test reports on file for Old Navy apparel containing heavy metal contamination. Cotton and low-percentage elastane blends do not inherently concentrate metals during production; risk would depend on supplier and dye batch, not material type.
Source, FDA ↗Allergen fragrance or finish residues
These are plain-weave pants with no marketed scent or special finish. Irritation risk from residual dyes or finishes is low after normal laundering; pre-wash is sufficient for individuals with sensitive skin or fragrance sensitivity.
The full breakdown
What it's made of and why it matters
Old Navy's Stevie Straight Pants are cotton-blend (typically 98% cotton, 2% spandex or similar elastane for stretch). Cotton is a natural fiber with minimal inherent chemical hazard; the spandex provides durability without the durability-related leaching risks of purely synthetic textiles. Blending allows retention of shape without relying on heavy chemical finishes. The standard weave construction suggests minimal chemical treatment beyond basic pre-finishing (scouring, bleaching).
The brand's record and disclosure
Old Navy (Gap Inc.) has no major product safety recalls on record for adult apparel in recent years and maintains basic compliance with US and EU textile standards. The company does not publicly disclose detailed chemical use policies for garment production, nor does it hold third-party certifications (e.g., OEKO-TEX, GOTS) that would signal enhanced screening for restricted substances. This absence of transparency is typical for mainstream fast fashion but does not indicate active hazard; it reflects limited public commitment to chemical disclosure.
How it compares in its category
Cotton-blend pants present lower concern compared to some synthetic textile alternatives. They carry lower risk than heavily dyed synthetic fabrics (which may contain azo dyes or antimony) and lower risk than garments with permanent-press finishes or flame retardants. Compared to certified organic cotton or OEKO-TEX certified alternatives, this product offers no public guarantee of restricted chemical avoidance, but the core material (high-percentage natural fiber) and intended use (everyday wear, minimal processing) both reduce typical hazard exposure.
If you buy it
Wash before first wear to remove any residual finishes or dyes; use warm water and a standard detergent. Avoid chlorine bleach if the spandex content is high (elastane degrades under chlorine). Dry on low heat or hang dry to preserve elastane longevity. Replace if seams fray, waistband elastic loses recovery, or significant pilling occurs; these are durability rather than safety signals, but worn waistbands can pinch or shift, creating fit hazards.
