Athleta Women's Reform Adjustable Sports Bra
Lower concern for basic sports bra materials, but brand gives no PFAS transparency.
This nylon-polyester sports bra typically lacks intentional water-repellent coating or stain-resistant coatings that introduce PFAS. Athleta offers no public PFAS policy, testing, or third-party certifications.

What Athleta Women's Reform Sports Bra is made of, ingredients and materials
The Reform Adjustable Sports Bra is constructed from a nylon and polyester blend with elastic components, a standard synthetic textile combination used in athletic wear. Nylon and polyester are petroleum-derived plastics that do not inherently leach harmful chemicals during normal wear, though both can be treated with finishing agents during manufacturing. The elastic likely contains synthetic rubber or elastane (spandex), which is chemically stable during typical use. No evidence suggests this specific material composition poses acute chemical hazard during normal wearing or laundering.
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 in synthetic textiles
Nylon and polyester are commonly dyed with azo dyes during production, which can release aromatic amines under sweat or repeated washing. Athleta does not disclose dye chemistry, so residual azo dye risk cannot be ruled out, though most finished garments on the US market comply with CPSIA limits for direct skin contact.
Formaldehyde / VOCs
Synthetic textiles often receive formaldehyde-based finishes for wrinkle resistance, shrinkage control, or shape retention. Athleta does not publish finish treatment information; off-gassing risk is low after manufacturing and typical laundering, but sensitive individuals may detect odor on first wear.
Source, ATSDR ↗Microfiber shedding during laundering
Synthetic fiber garments shed microplastics during washing; this is an environmental concern rather than direct health hazard. Washing in cold water and using a microfiber-catching laundry bag can reduce shedding volume, though complete prevention is not feasible with synthetic textiles.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Elastane (spandex) stability and degradation
Elastane fibers in sports bras are chemically stable during normal wear and washing. No documented leaching or skin reaction hazards are associated with quality elastane in direct contact with skin. Degradation occurs over time with use but produces fiber breakage, not chemical release.
Heavy metals
US textile regulations limit lead, cadmium, and other heavy metals in apparel dyes. No recalls or testing failures have been reported for Athleta sports bras. Risk is low but unverified by brand disclosure.

The brand's record and disclosure
Athleta (owned by Gap Inc.) has not published comprehensive PFAS or chemical hazard disclosures for individual products, though parent company Gap Inc. has made some supply-chain sustainability commitments. The brand does not list certifications like GOTS (Global Organic Textile Standard) or Bluesign for this product, meaning manufacturing chemical controls are not independently verified. No recalls or chemical contamination incidents have been documented for Athleta sports bras. Transparency on dye sourcing and finish treatments remains minimal.
How it compares in its category
Most mainstream sports bras (Nike, Lululemon, Brooks) use identical nylon/polyester/elastane blends without disclosed chemical hazards. Certified organic or low-impact dye alternatives (e.g., Patagonia, Allbirds) command higher prices and offer more chemical traceability. Athleta sits in the middle market with comparable material safety to peers but weaker transparency than premium sustainable brands. The Reform line does not carry special certifications that would differentiate it chemically.
If you buy it
Wash in cool water with mild detergent to minimize dye bleeding and preserve elastic integrity; avoid chlorine bleach and fabric softeners, which can degrade synthetic fibers. Do not expose to direct heat (high dryer temperature, iron, or prolonged sunlight), as polyester and elastane soften above 140F and can lose shape. Replace when elastic loses recovery (typically 12-24 months with regular use) to avoid poor support. No special precautions needed for skin contact or child exposure beyond standard garment care.
