Aerie Skinny Strap Voop Bikini Top Women's NULL
Lower concern, standard swimwear with no water-repellent coating treatment flagged; Aerie has not publicly committed to PFAS elimination.
This bikini top uses typical nylon-spandex swimwear without visible water-repellent or stain-resistant coatings commonly carrying PFAS. Aerie does not publish PFAS-free claims or certifications.

What Aerie Skinny Strap Voop Top Women's NULL is made of, ingredients and materials
This bikini top is a nylon and spandex (elastane) blend, the industry standard for swimwear construction. Nylon provides durability and chlorine/saltwater resistance, while spandex enables stretch and fit recovery. Neither material requires flame retardant treatment, heavy metal dyes, or water-repellent coatings that typically introduce chemical hazards in apparel, making this construction relatively straightforward from a safety standpoint.
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.
Heavy metals
Colored nylon swimwear may contain trace heavy metals (cadmium, lead, chromium) from industrial dyes, particularly in deep blues, blacks, and greens. Aerie does not publish heavy-metal testing results; EU/US apparel regulations set limits, but enforcement for swimwear is inconsistent and third-party verification is absent for this brand.
Source, FDA ↗Microplastic shedding
Synthetic swimwear (nylon/spandex) releases microfibers during wear and washing. This is a known property of the material class, not specific to Aerie, but becomes relevant with repeated chlorine exposure and laundering. Regular rinsing and air-drying minimize fiber release compared to machine washing and high heat.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Azo dyes
Nylon swimwear commonly uses azo dyes, some of which can break down into carcinogenic amines. No public testing of Aerie swimwear for restricted azo dyes (e.g., benzidine-based) is available; standard industry practice and lack of documented violations suggest compliance with EU/US restrictions, but Aerie does not publicly commit to azo-dye screening.
Formaldehyde / VOCs
Formaldehyde resin finishes are used in some apparel for wrinkle resistance or dye fixation. Swimwear typically avoids these because water exposure would activate off-gassing and nylon does not require wrinkle treatment. No evidence Aerie applies formaldehyde resins to this product.
Source, ATSDR ↗Allergens from fragrance or finishing chemicals
No public reports of allergic reactions or fragrance additives in Aerie swimwear. Spandex itself can irritate sensitive skin, especially in chlorinated water, but this is material-inherent, not product-specific.
How is this PFAS grade calculated?
The brand's record and disclosure
Aerie is owned by American Eagle Outfitters, which publishes a corporate sustainability report but does not provide detailed chemical composition transparency or swimwear-specific safety certifications. The brand has not faced major public chemical recalls or controversies. No credible third-party testing results (e.g., Greenpeace Detox Campaign data) on Aerie swimwear are on record, leaving chemical practices largely unverified but also without documented violations.
How it compares in its category
This product sits in the mainstream swimwear tier. It carries similar material composition to brands like Athleta, Gap Body, and Old Navy, all using untreated nylon/spandex blends without intentional water-repellent coating or flame-retardant treatment. It lacks third-party certifications (e.g., GOTS, Oeko-Tex Standard 100) that competitors like Patagonia or some direct-to-consumer brands offer, but also carries no documented chemical risk above category baseline.
If you buy it
Wash in cool water before first wear to remove any residual dyes or finishes. Rinse after chlorine or saltwater exposure to extend fabric life and reduce microplastic shedding. Air-dry only; avoid high heat or direct sunlight for extended periods, which can degrade spandex elasticity. Replace when elastic noticeably loses recovery or fabric shows pilling or thinning, typically after 50-80 wears with proper care.
