Andie Women's Swim Andie The Amalfi One Piece Swimsuit
Skip until brand discloses water-repellent coating treatment chemistry, likely PFAS but unconfirmed.
Andie's Amalfi swimsuit uses nylon with water-repellent finish, a category where PFAS-based water-repellent coating coatings remain common. The brand doesn't disclose what chemistry protects the fabric.

What Andie Women's Swim Andie The Amalfi One is made of, ingredients and materials
This suit is nylon/polyamide blend with a water-repellent coating (water-repellent coating) coating of unspecified chemistry. Nylon itself is stable and does not leach endocrine disruptors under normal use. The water-repellent coating finish is the concern, historically, most commercial water-repellent coating treatments use legacy PFAS (perfluorocarbons) or newer replacements that may carry similar toxicity profiles. Andie does not publicly disclose whether their water-repellent coating is PFAS-free or GenX/fluorine-based, leaving exposure status unclear.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Andie does not disclose water-repellent coating treatment. Most commercial swimwear water-repellent coating uses fluorinated compounds (PFAS or alternatives). Absorption through skin during water exposure is considered low under normal conditions, but repeated use and water immersion increase contact time. Grade reflects high likelihood of PFAS presence without independent verification.
Source, ATSDR ↗Microplastics
Nylon fibers can shed during washing and wear, especially if the water-repellent coating degrades and fibers become abraded. Microplastic migration to water ecosystems is a known consequence of synthetic swimwear use. Proper cold-water rinsing and avoiding mechanical agitation may reduce shedding.
Source, EPA ↗What’s reassuring
Formaldehyde / VOCs
No public recalls or testing reports of excess formaldehyde in Andie swimwear. Nylon dyes and any water-repellent coating topcoat may contain trace formaldehyde releasers; standard textile industry practice minimizes this, but no third-party certification (OEKO-TEX) is evident for this product.
Source, ATSDR ↗Azo dyes (banned carcinogenic dyes)
The Amalfi colorway (likely blues or earth tones) is unlikely to use illegal azo dyes in US-distributed products, as major retailers enforce bans. No specific testing or controversy on record for this brand, but lack of certification means reliance on supplier compliance alone.
Allergic reaction to fragrance or dyes in finish
No fragrance additive is typical in swimwear. Nylon and water-repellent coating chemicals may trigger contact dermatitis in sensitized individuals, but Andie has no publicly documented adverse reactions. Test on small skin area if you have textile sensitivities.
The full breakdown
The brand's record and disclosure
Andie has not published chemical ingredient lists, PFAS phase-out commitments, or third-party certifications (e.g., OEKO-TEX, bluesign) on this product. No major recalls or chemical controversies appear in public records for this brand. The silence on water-repellent coating chemistry is notable, competitors such as Speedo and Patagonia have begun disclosing or eliminating PFAS in swimwear, making Andie's non-disclosure a competitive red flag for health-conscious buyers.
How it compares in its category
Standard nylon swimwear typically carries water-repellent coating treatment; few budget brands certify PFAS-free finishes. Higher-end alternatives (Patagonia, Girlfriend Collective) increasingly market PFAS-free or minimally treated options, though at premium prices. Andie's price point ($90-120 range) positions it mid-market, where water-repellent coating chemistry varies widely and disclosure is sparse. Without testing or certification, this product cannot be confidently rated better or worse than peers on chemical hazards alone.
If you buy it
Rinse the suit in cold fresh water after each saltwater or chlorinated-pool use to reduce absorption of waterborne contaminants and extend water-repellent coating life. Avoid hot water or high-heat drying, which can degrade nylon fibers and may accelerate coating breakdown. Replace the suit every 1-2 years or when the water-repellent coating noticeably diminishes (water beads less effectively). Consider requesting Andie's water-repellent coating supplier or chemistry before purchase; explicit disclosure from the brand would shift this to 'buy' tier.
