J.Crew Women's Long-Torso Lana One-Piece
Lower concern for typical swimwear. J.Crew discloses nothing about PFAS in textiles.
This is a standard nylon-spandex one-piece with no known water-repellent or stain-resistant treatment claims. J.Crew makes no public PFAS statements for apparel.

What J.Crew Women's Long-Torso Lana One-Piece is made of, ingredients and materials
This one-piece uses a nylon/spandex (elastane) blend, standard construction for chlorine-resistant swimwear. Nylon itself is a synthetic polymer with minimal leaching risk in aqueous environments. Spandex adds stretch and recovery but degrades over time with UV and chlorine exposure, which is normal wear rather than a safety issue. The "water-resistant" claim likely refers to quick-dry properties, not waterproofing treatments that would introduce chemical additives.
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.
Formaldehyde / VOCs
Nylon swimwear may be treated with formaldehyde-based resins for water resistance or color-setting. J.Crew provides no material safety data sheet or finish disclosure, so presence cannot be ruled out. Standard practice in mid-market brands is to use these finishes without explicit labeling.
Source, ATSDR ↗Azo dyes and colorfast processes
The garment's dye composition is not disclosed. Azo dyes banned in some jurisdictions (those cleaving to carcinogenic amines) are still legal and used in US-market apparel. J.Crew does not claim Oeko-Tex certification for this item, so testing for banned azo dyes is not verified.
Spandex degradation and microfiber shedding
Elastane (spandex) degrades with UV, chlorine, and heat, shedding microfibers into water and landfill. This is a known concern for all synthetic swimwear and is not specific to J.Crew, but regular replacement and gentle care reduce the rate.
PFAS
The "water-resistant" descriptor suggests a finish, though nylon has inherent quick-dry properties. If a water-repellent coating (water-repellent coating) coating is applied, traditional formulations contain long-chain PFAS. J.Crew's silence on chemistry leaves this unconfirmed but plausible for a marketed resistant feature. (Graded separately, PFAS score 65/100 reflects lower risk for swimwear context.)
Source, ATSDR ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No recalls or reports of heavy metal contamination in J.Crew swimwear. Standard nylon dyeing does not inherently require lead or cadmium; however, independent testing is absent.

The brand's record and disclosure
J.Crew does not publicly disclose PFAS or chemical composition details for swimwear lines, which is typical of mainstream apparel brands but falls short of transparency leaders like Patagonia. The brand has no recorded recalls or safety complaints specific to this garment. J.Crew follows US textile standards (Oeko-Tex or equivalent certifications are not visibly claimed for this item), so baseline legal compliance is assumed but enhanced safety vetting is absent.
How it compares in its category
Nylon/spandex is the industry standard for one-piece swimwear; alternatives (polyester blends, other synthetics) carry similar hazard profiles. J.Crew's pricing and positioning sit in the mid-market segment where chemical disclosure is limited compared to performance or luxury brands. The long-torso cut is a fit variation, not a material or safety differentiator.
If you buy it
Rinse thoroughly after chlorine or saltwater use to extend spandex life and minimize any potential residue buildup. Avoid prolonged direct sunlight storage and high-heat drying, which accelerates elastane breakdown. Replace when elastic loses recovery (typically 1-2 years of regular use) rather than when material shows minor wear. Wash in cool water with mild detergent; do not bleach.
