Andie Women's Snap Long Torso One-Piece Swimsuit
Avoid unless Andie confirms water-repellent coating is PFAS-free; water-repellent finishes typically use PFAS.
This nylon-spandex swimsuit offers water resistance through a likely fluorinated coating, but Andie discloses nothing about PFAS presence. Modern swimwear durability almost always requires such treatments.

What Andie Women's Snap Long Torso One-Piece is made of, ingredients and materials
This swimsuit is a nylon/spandex blend, likely 82% nylon and 18% spandex based on typical Andie construction. Nylon is a synthetic polyamide; spandex (elastane) provides stretch recovery. The water-repellent (water-repellent coating) finish applied to the fabric surface is the primary chemical concern, as water-repellent coating coatings historically rely on PFAS "forever chemicals" (PFAS) to repel water and chlorine. The yarn dyes used in the manufacturing process also warrant scrutiny, though azo dyes in swimwear are now relatively restricted in most Western production.
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
Water-repellent finishes on swimwear conventionally use PFAS compounds. Andie has not confirmed PFAS-free alternatives. PFAS can leach into skin contact and persist environmentally after disposal.
Source, ATSDR ↗Azo dyes in synthetic fibers
Nylon yarn dyeing may involve azo colorants. Restricted azo dyes (those that break down to carcinogenic amines) are prohibited in EU and most major markets, but non-restricted azo dyes remain common. No specific test data for this Andie product is publicly available.
Microfiber shedding during wear and wash
Nylon/spandex blends can shed microfibers into water during swimming and laundering, contributing to aquatic microplastic pollution. This is a use-phase environmental hazard rather than a direct health risk, but relevant to long-term product impact.
Elastane (spandex) degradation over time
Spandex loses elasticity with age, heat, and chlorine exposure. Degraded elastane can crack and peel, creating choking or ingestion hazard if fragments break free, particularly for children. Not unique to Andie but inherent to the material.
What’s reassuring
Dye transfer or bleeding in storage
No specific reports of color bleeding or dye transfer from Andie swimwear. Nylon generally holds dyes well when properly cured, and modern textile regulations restrict unstable dyes. Possible only if manufacturing quality control lapses occur.
The full breakdown
The brand's record and disclosure
Andie has not publicly disclosed whether its water-repellent coating finishes are PFAS-free, nor has the brand issued a formal statement on PFAS phase-out timelines or alternative coating chemistry. No major recalls or safety violations for this product line are on record. The brand does not appear to hold third-party certifications (such as Oeko-Tex or Bluesign) that would independently verify chemical safety, which limits transparency relative to competitors like Cupshe or higher-end lines that seek such credentials.
How it compares in its category
Most mass-market swimwear brands still use PFAS-based water-repellent coating finishes as standard practice, so Andie is not uniquely problematic in this regard. Premium swimwear brands (e.g., Summersalt, Lively) and some ethical labels increasingly offer PFAS-free options or disclose their coatings explicitly. Budget swimwear rarely discloses water-repellent coating chemistry at all. Andie's silence places it in the middle of the market, not worst-in-class but also not demonstrating lower concern than peers.
If you buy it
Wash the swimsuit by hand in cool water before first use to remove any loose dyes or finish residues. Avoid hot water and machine washing, which can accelerate coating degradation and leaching. Air-dry flat; do not tumble dry. Replace the suit when elasticity visibly declines (typically 50-100 wears for nylon/spandex blends) or if the water-repellent coating visibly fails (fabric stops repelling water). If PFAS exposure concerns you, contact Andie directly to request coating composition before purchase.
