Rip Curl Women's Bossa Nova One-Piece Swimsuit

Bad

Moderate PFAS concern, swimwear water-repellent coating finishes often contain PFAS; Rip Curl makes no public disclosure.

Verdict: Skipwater-repellent coating finish likely contains PFAS with no brand disclosure; nylon itself poses minimal acute risk if cared for properly.

Bossa Nova is a nylon one-piece with water-repellent treatment, a common vector for PFAS in apparel. Rip Curl provides no public statement on PFAS use or avoidance.

PFAS

water-repellent coating finishes on nylon swimwear commonly use PFAS compounds. No public information confirms or denies PFAS in Rip Curl's specific formulation, but industry standard practice and the brand's silence suggest PFAS-based chemistry is probable rather than confirmed absent.

Formaldehyde / VOCs

Some water-repellent coating and water-repellent treatments historically used formaldehyde-based crosslinkers. Formaldehyde off-gassing is typically minimal in finished swimwear and dissipates with rinsing, but cannot be ruled out without manufacturer disclosure.

water-repellent coating migration into water/skin

If water-repellent coating contains PFAS, degraded or worn coatings may leach low levels into pool/ocean water or contact skin. Direct dermal absorption of intact water-repellent coating is low, but degradation accelerates with wear and heat exposure.

What’s reassuring

Azo dyes in synthetic textiles

No specific safety alerts or recalls exist for Rip Curl swimwear related to azo dyes. Nylon swimwear from major manufacturers typically meets international dye standards, though detailed dyestuff disclosure is rare in this category.

Microplastics

Nylon swimwear sheds microfibers during washing like all synthetic textiles, but this is a shared category issue, not specific to Rip Curl. No product-specific data on shedding rates is available.

The full breakdown

What it's made of and why it matters

This swimsuit is nylon (polyamide) with a water-repellent coating (water-repellent coating) finish. Nylon itself is a stable synthetic polymer with low leaching risk in normal use. The water-repellent coating finish, however, is the concern: historically these finishes rely on fluorochemical coatings, often PFAS-based, to achieve water repellency and stain resistance. Rip Curl does not publicly disclose the chemistry of its water-repellent coating treatment, leaving uncertainty about PFAS presence.

The brand's record and disclosure

Rip Curl has not issued public statements about PFAS in its product lines or water-repellent coating finishes. The brand has not pursued PFAS-free or PFOA-free certifications visible in its marketing. No major recalls or safety violations are on record for this specific product line. The silence on this issue is notable given industry movement toward transparent disclosure by competitors.

How it compares in its category

Most mainstream swimwear brands (including Rip Curl) use water-repellent coating finishes without disclosure. Higher-end or eco-focused competitors (e.g., Patagonia) explicitly state PFAS-free water-repellent coating or use alternative water-resistance methods. Budget alternatives from fast-fashion retailers often have identical water-repellent coating opacity. This product sits in the middle: it's a reputable brand with functional construction, but offers no transparency advantage over cheaper options.

If you buy it

Rinse the suit in fresh water after salt water or chlorine exposure to extend water-repellent coating life and reduce any leaching from degraded finish. Air dry in shade; avoid high heat (dryer, direct sun for extended periods), which can accelerate coating breakdown. Replace when water-repellent coating noticeably degrades (water stops beading) rather than washing aggressively to restore it. Consider requesting Rip Curl's water-repellent coating supply chain information directly if PFAS content is a personal priority.
