Andie Swim Women's Copacabana One Piece Swimsuit
Typical swimwear with likely water-repellent coating, lower certainty without brand transparency on treatments.
Andie's Copacabana swimsuit is a nylon-spandex one-piece that almost certainly uses a water-repellent coating finish, historically associated with PFAS chemicals. The brand makes no public disclosure about PFAS content or coating composition.

What Andie Swim Women's Copacabana One Piece is made of, ingredients and materials
This swimsuit is a nylon and spandex (elastane) blend with a water-resistant finish applied to the fabric. Nylon is a durable synthetic polymer that holds color well and resists chlorine and saltwater better than many natural fibers. The spandex provides stretch and recovery. The water-resistant finish, almost certainly a water-repellent coating (water-repellent coating) coating, is the primary PFAS exposure vector in modern swimwear, as fluorochemical coatings are the industry standard for water beading and quick-dry performance.
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.
water-repellent coating (water-repellent coating) fluorochemical finish
Water-resistant nylon swimwear almost universally uses fluorochemical water-repellent coating coatings, which are PFAS-based compounds. Andie does not disclose the specific chemistry, but industry practice and the product description (water-resistant finish) strongly indicate their use. See separate PFAS assessment for exposure grading.
Azo dyes in synthetic textiles
Nylon is commonly dyed with azo dyes, some of which are restricted under international regulations (EU REACH, GOTS) but still used in non-certified mass-market swimwear. Andie provides no dye chemistry or safety certification, so azo dye risk cannot be ruled out, though most major swimwear brands have moved to lower-concern alternatives.
Heavy metals
Nylon swimsuits require colorfast treatments to withstand chlorine and UV exposure; some older or unregulated dye fixatives have used heavy metal mordants (copper, chromium). No recalls or reports specific to Andie, but lack of certification or testing disclosure means this hazard is not verified as absent.
Source, FDA ↗Spandex degradation and microfiber release
Spandex fibers shed and degrade over time, especially when exposed to UV, heat, and chemicals in chlorine or saltwater. Modern swimwear spandex is not typically contaminated with heavy metals, but the microfiber shedding itself is an environmental and potential inhalation concern during washing. No product-specific data available for Andie.
Contact dermatitis from dyes, finishes, or residual chemicals
Nylon swimwear can cause skin irritation in sensitive individuals due to dye residues, chlorine interaction with finish chemicals, or spandex friction. No widespread reports for Andie specifically, but the lack of hypoallergenic or OEKO-TEX certification means chemical residue testing is unverified.
The full breakdown
The brand's record and disclosure
Andie does not publicly disclose material treatment details or PFAS use in their marketing or available documentation. The brand has no known certifications (GOTS, bluesign, OEKO-TEX) that would indicate third-party chemical screening. No major recalls or safety controversies are on record for this brand or product line, but the silence on water-repellent coating chemistry is consistent with most mass-market swimwear producers and reflects an industry-wide lack of transparency rather than a specific Andie failing.
How it compares in its category
This product sits squarely in the mainstream swimwear market. Most one-piece suits from brands at similar price points (mid-range athletic/fashion swimwear) use nylon/spandex with fluorochemical water-repellent coating finishes. Alternatives marketed as PFAS-free or sustainable (e.g., Patagonia, Girlfriend Collective) typically cost 2-3x more and use other water-resistant technologies or accept reduced water repellency. Andie's positioning and lack of premium material claims place it in the typical PFAS exposure category for its market segment.
If you buy it
Rinse the suit in fresh water after each saltwater or chlorinated water use to reduce chemical absorption and extend coating life. Wash gently in cool water and lay flat to dry; avoid high heat, bleach, and fabric softeners, which degrade the water-repellent coating finish and spandex elasticity faster. Replace the suit every 1-2 years of regular use, as the elastic weakens and the water-resistant coating breaks down. Store it dry in a cool place, away from direct sunlight.
