Skip or contact Nike; swimwear water-repellent coating often uses PFAS, but brand discloses nothing.

Verdict · SkipNylon/polyester blend swimwear with unknown water-repellent coating treatment; no major non-PFAS hazards documented, but PFAS opacity and brand silence warrant direct contact before purchase.

Hydralock line uses water-repellent coating treatment common in performance swimwear, historically reliant on PFAS chemistry. Nike offers no PFAS disclosure or certification.

What Nike Women's Hydralock Luxe Piece Swimsuit is made of, ingredients and materials

This swimsuit is a nylon/polyester blend, both synthetic fibers chosen for stretch, durability, and quick-dry properties in water contact. The 'Hydralock' branding indicates a water-repellent (water-repellent coating) finish applied to the fabric, which typically involves fluorinated or non-fluorinated chemical treatments. The blend itself is stable under normal swimming conditions, but the water-repellent coating is the chemical unknown here, Nike has not publicly disclosed whether Hydralock uses PFAS or PFAS alternatives.

Waterproof / stain-resistant treatment

Water-repellent coating treatments have historically used PFAS.

65/ 100
🫧

Microfiber shedding during washing

Synthetic nylon/polyester blends shed microplastics with repeated laundering, a known feature of the material class. This is environmental rather than direct-to-wearer risk, but relevant to product lifecycle. Washing in a mesh bag and using cold water reduces shedding.

70/ 100
⏳

water-repellent coating degradation and leachables

Water-repellent coatings degrade over time and with washing; if the coating uses fluorinated compounds (most likely given the marketing focus on 'Hydralock'), breakdown byproducts are unknown and undisclosed. This is speculative without chemical analysis, but the non-transparency heightens concern.

70/ 100
⏳

Chlorine and saltwater degradation of fabric integrity

Repeated exposure to pool chlorine or saltwater can degrade nylon and polyester over time, particularly at seams and stretch panels. This affects garment lifespan and may increase microfiber shedding, not direct chemical toxicity.

70/ 100

What’s reassuring

✅

Azo dyes and synthetic dye residues

Nylon and polyester swimwear routinely use synthetic colorants, but no safety alerts or contamination reports are documented for Nike Hydralock specifically. Standard dyeing processes for apparel are regulated, and direct skin exposure to dye residue is minimal after rinsing.

95/ 100
💨

Formaldehyde / VOCs

Apparel finishing sometimes involves formaldehyde-based resins for crease resistance and color fastness. No such reports exist for this product; modern apparel manufacturing typically uses low-formaldehyde or formaldehyde-free processes, but pre-purchase washing is still advised.

How is this PFAS grade calculated?

The brand's record and disclosure

Nike has faced scrutiny over PFAS in apparel and has made some commitments to phase out long-chain PFAS by 2030, but disclosure remains incomplete for specific product lines like swimwear. The company does not publish material safety data sheets or water-repellent coating chemistry details for most garments. No recalls or safety violations tied to this specific swimsuit are on record, but the lack of transparency is a red flag for informed purchasing.

How it compares in its category

Most mainstream swim brands (Speedo, Roxy, Lands' End) use similar nylon/polyester blends with water-repellent treatments, making this product typical rather than exceptional. Brands that explicitly avoid PFAS in water-repellent coating (using silicone or polyurethane alternatives) tend to market that fact prominently; Nike's silence suggests either standard PFAS-based treatment or reluctance to commit. For comparison, some eco-focused swimwear brands (e.g., Patagonia Clearwater line) disclose PFAS-free certifications.

If you buy it

Wash before first use to reduce surface treatments. Machine wash in cool water with mild detergent; avoid fabric softeners, which can interact with water-repellent coating coatings. Air dry flat to preserve coating integrity; high heat (dryer) can degrade both synthetic fibers and water-repellent chemicals. Replace when elasticity fails or water beading stops, typically after 50-100 wears. If PFAS exposure is a primary concern, contact Nike customer service to request water-repellent coating ingredient disclosure before committing.
