What Aerie Skinny Strap Voop Ribbed Bikini Top is made of, ingredients and materials
This bikini top is a nylon and spandex blend, the industry standard for swimwear. Nylon is a synthetic polyamide polymer that does not leach monomers into skin or water under normal wear conditions. Spandex (polyurethane elastomer) provides stretch and is chemically stable in typical use. Neither material requires flame retardants, heavy metal pigments, or formaldehyde resins in basic swimwear construction.
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 textile coloring
Nylon bikini tops are routinely dyed with azo compounds. Aerie has not disclosed whether this top complies with OEKO-TEX Standard 100 restrictions on restricted azo dyes. Skin contact risk is low; concern is primarily environmental release during manufacture and laundering.
Spandex degradation and microfiber shedding
Spandex fibers break down with UV exposure and repeated stretching, shedding microplastics into wash water. This is a material-class issue affecting all synthetic swimwear, not Aerie-specific. Severity increases with higher wash frequency and hot water use.
Allergic contact dermatitis from dyes or elastic components
Spandex and azo dyes are recognized allergens for a small subset of individuals with textile sensitivity. Symptoms include localized rash where elastic waistband or dyed areas contact skin. Risk is individual and unrelated to Aerie's specific formulation; patch test if you have known dye sensitivity.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Basic nylon/spandex bikini tops typically do not receive formaldehyde-based wrinkle-resistant or anti-shrink treatments. No evidence suggests Aerie applies such finishes to this line. Risk is minimal if the top is rinsed before first wear.
Source, ATSDR ↗Heavy metals
Modern nylon textile dyes are not routinely contaminated with lead, cadmium, or chromium in mass-market apparel. No public recalls or test failures for Aerie swimwear on heavy metal grounds exist. Compliance with US textile safety standards is presumed.

The brand's record and disclosure
Aerie, a subsidiary of American Eagle Outfitters, does not publish detailed chemical testing or PFAS statements for individual swimwear SKUs. The brand has not disclosed formal compliance with OEKO-TEX or bluesign certifications for this line. No recalls or documented chemical safety controversies specific to Aerie swimwear have been publicly reported. Transparency on dye sources and finishing treatments remains limited.
How it compares in its category
Nylon/spandex bikini tops are the baseline construction across mass-market brands. This product lacks marketed water-repellent or stain-resistant finishes, which is a positive indicator for lower PFAS treatment. Competitors offering similar price-point basic bikini tops (e.g., Target, H&M Essentials) use identical material profiles and show no material safety advantage. No premium sustainability or certification benefit is claimed for this Aerie line.
If you buy it
Rinse the top in cool fresh water after saltwater or chlorine exposure to extend dye stability and fiber life. Machine wash in cold water with mild detergent; avoid fabric softeners and bleach, which degrade spandex elasticity. Lay flat to dry; heat and direct sunlight fade nylon dyes over time. Replace when elastic loses recovery (typically 1-2 years of regular seasonal use); degraded spandex may lose shape integrity but poses no toxicity risk.
