Lands' End Women's DD-Cup Tummy Control Chlorine Resistant Soft Cup Tugless One Piece Swimsuit

Bad

High PFAS risk. Chlorine-resistant swimwear typically uses PFAS-based water-repellent coating finishes.

Verdict: SkipChlorine-resistant swimwear likely contains undisclosed PFAS; no other major hazards documented, but transparency gap warrants cautious use and proper care.

This chlorine-resistant swimsuit likely relies on a water-repellent coating to keep working in pools. Lands' End won't say if that treatment contains PFAS.

What’s concerning

♾️

Waterproof / stain-resistant treatment

Water-repellent treatments have historically contained PFAS chemicals.

Category baseline

PFAS exposure happens more often with clothing products.

No PFAS disclosure

The company has not publicly discussed PFAS in this product.

PFAS

Chlorine-resistant swimwear typically employs PFAS-based water-repellent coating finishes. Lands' End does not disclose the specific chemistry, making it reasonable to assume standard industry practice. Skin contact and potential migration of treatment compounds into pool water are the primary exposure routes.

Synthetic fiber microfiber shedding

Nylon and polyester fabrics shed microscopic fibers during washing and wear, particularly if the water-repellent coating degrades over time. While the health risk from swimwear microfiber shedding is not well-established, accumulation in aquatic environments is documented. Frequent washing accelerates shedding.

70/ 100

Elastic degradation and material leaching

Spandex elastane in the waistband and leg bands can degrade with repeated chlorine and hot-water exposure, potentially releasing oligomers. Degraded elastics are a sign to replace the garment. This is not specific to Lands' End but reflects the limits of elasticized swimwear durability.

What’s reassuring

Azo dyes in polyester

No specific safety alerts or banned azo dyes are on record for Lands' End swimwear. Standard polyester textiles may use azo dyes, which can release aromatic amines under certain conditions, but this is not a recognized hazard for swimwear under normal use.

Formaldehyde / VOCs

No formaldehyde-releasing resins are known to be used in Lands' End swimwear production. Swimwear finishes typically use fluorinated or water-based systems, not formaldehyde resin. Direct contact dermatitis is not a documented concern for this product.

The full breakdown

What it's made of and why it matters

This swimsuit is a nylon-polyester blend treated with a water-repellent coating (water-repellent coating) finish to resist chlorine degradation and maintain color. Chlorine-resistant treatments in swimwear commonly use PFAS-based chemistry (perfluorinated compounds) to create the water and chlorine barrier, though Lands' End does not publicly specify which chemistry they employ. The base fabrics themselves (nylon and polyester) are stable synthetic fibers unlikely to leach monomers under normal wear, but the treatment layer is the source of potential concern.

The brand's record and disclosure

Lands' End does not disclose the chemical composition of its swimwear treatments on product labels or in publicly available safety documentation. The company has no known certifications (such as GOTS or Bluesign) that would restrict PFAS use. No product recalls or chemical safety controversies specific to this swimsuit model are on record, but the lack of transparency on water-repellent coating finish chemistry reflects an industry-wide pattern among legacy apparel brands.

How it compares in its category

Most chlorine-resistant swimwear relies on PFAS or PFAS-like fluorinated treatments; this Lands' End style is typical in that regard. Brands such as Patagonia and some sportswear lines are beginning to use non-PFAS water-repellent coating alternatives (e.g., wax-based or silicone coatings), but these remain less common and often less effective against chlorine. For a mainstream retailer product at this price point, chlorine resistance without disclosed safer chemistry is the standard.

If you buy it

Wash in cool or warm water with mild detergent; avoid hot water, which can accelerate coating breakdown and potential leaching. Air dry rather than machine drying to preserve the water-repellent coating finish. Replace when the suit begins to lose shape, elastic fails, or color fades significantly, typically after 50-80 wears or 1-2 seasons. Limit exposure to strong sunlight when not in use, as UV can degrade the treatment layer.
