Skip or contact Nike; swimsuit likely has finish but brand discloses nothing about PFAS.
Nike swimsuits typically apply water-repellent coating finishes to synthetic fabrics for water shedding. Nike provides no PFAS disclosure or PFAS-free claim for this product.

What Nike Women's V-Back One Piece Swimsuit is made of, ingredients and materials
This swimsuit is constructed from a polyester/nylon blend, both synthetic polymers that are stable in normal use and do not leach chemicals into skin or water at body temperature. The water-repellent coating (water-repellent coating) finish applied to the fabric, which makes it shed water and dry faster, is the material concern; water-repellent coating treatments on swimwear are historically fluorocarbon-based (PFAS), though some brands have begun switching to fluorocarbon-free alternatives. Nike has not publicly specified which type is used on this model, creating uncertainty about long-term wear and eventual fabric degradation.
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 coatings on swimwear are typically fluorocarbon-based; Nike has not disclosed whether this model uses legacy PFAS or newer alternatives. Exposure during wear is low but accumulates if fabric degrades or is washed repeatedly.
Source, ATSDR ↗Microplastics
Polyester garments shed microfibers when washed, particularly in their first five to ten cycles; this is inherent to synthetic fiber and affects most commercial swimwear equally, not a Nike-specific issue.
Source, EPA ↗What’s reassuring
Formaldehyde / VOCs
No recalls or reports of formaldehyde contamination in Nike swimwear. Modern polyester athletic swimwear typically uses low-formaldehyde dye systems, though independent testing of this specific product has not been published.
Source, ATSDR ↗Azo dyes (carcinogenic breakdown products)
Azo dyes are restricted in many jurisdictions; Nike swimwear is unlikely to contain banned azo dyes, but brand does not publicly certify compliance with OEKO-TEX or similar standards for this model.
Antimony in polyester fiber
Antimony is used as a catalyst in polyester production and can remain as a trace residue; levels in finished athletic wear are typically below concern thresholds, and no Nike swimwear has been reported with elevated antimony.
How is this PFAS grade calculated?
The brand's record and disclosure
Nike has made limited public commitments on PFAS phase-out in apparel and has not transparently disclosed the chemistry of water-repellent treatments in its swimwear line. The brand has faced scrutiny for vague environmental claims and slow chemical transparency adoption compared to outdoor/athletic peers like Patagonia or Arc'teryx. No major safety recalls or toxicity incidents have been documented for Nike swimwear, but the absence of third-party testing or certification (such as OEKO-TEX or bluesign) means potential hazards remain unverified.
How it compares in its category
This product sits in the mainstream athletic-luxury segment; typical competitors (Speedo, TYR, Adidas) also use polyester with undisclosed water-repellent coating finishes. More transparent alternatives include chlorine-resistant swimwear marketed as PFAS-free or certified by environmental standards, though these are less common and often more costly. Most conventional swimwear in this price range lacks detailed chemical disclosure, making Nike neither worse nor notably better in transparency, it is representative of the category norm.
If you buy it
Rinse the swimsuit in fresh water immediately after saltwater or chlorinated use to reduce salt/chlorine accumulation and extend water-repellent coating performance; wash in cool water with mild detergent and air-dry to prevent fabric degradation and maintain water-repellent properties. Avoid bleach, fabric softeners, and high heat, as these degrade synthetic fibers and any coating. Replace when elastic loses recovery, seams fray, or water no longer beads on the fabric, typically 12 to 18 months of regular use. If you are concerned about PFAS, contact Nike directly for specific chemistry disclosure before purchase.
