Lands' End Women's Tugless Sporty DDD-Cup Chlorine Resistant One-Piece Swimsuit

Bad

High PFAS risk. Avoid unless Lands' End discloses or verifies water-repellent coating chemistry.

Verdict: SkipNylon/polyester blend with undisclosed water-repellent coating finish; chlorine resistance typically PFAS-dependent; use with caution until Lands' End confirms chemistry.

Chlorine-resistant swimsuits typically need water-repellent coating coatings that historically contain PFAS to handle repeated chlorine exposure. Lands' End makes no public statement about PFAS use or absence.

What’s concerning

♾️

Waterproof / stain-resistant treatment

Water-repellent treatments have historically contained PFAS chemicals.

65/ 100
♾️

Category baseline

PFAS exposure happens more often with clothing products.

70/ 100
♾️

No PFAS disclosure

The company has not publicly discussed PFAS in this product.

85/ 100
💨

Formaldehyde / VOCs

Cross-linking resins used in chlorine-resistant treatments may contain or release formaldehyde; Lands' End does not specify finishing agent composition. Risk is present but unconfirmed by testing or disclosure.

water-repellent coating degradation and leaching

Fluorinated water-repellent coating coatings on textiles are known to degrade during washing and wear, releasing particles and dissolved compounds. Chlorine exposure may accelerate this; Lands' End's silence on the type of water-repellent coating used makes the degradation risk and chemical identity unclear.

45/ 100
🫧

Microplastic shedding from synthetic fibers

Nylon/polyester blends shed microfibers during use and laundering, contributing to aquatic microplastic pollution. This is inherent to the material class, not specific to Lands' End, but notable for a product worn in chlorinated pools where fibers enter wastewater.

20/ 100

What’s reassuring

Azo dyes and synthetic colorants

Nylon and polyester are often dyed with azo compounds; Lands' End does not disclose dye chemistry or compliance with restricted substance lists. No recalls or contamination reports are on record for this brand's swimwear.

95/ 100

Antimony in polyester fiber

Polyester synthesis sometimes involves antimony trioxide as a catalyst; finished fiber typically contains minimal residual antimony, but Lands' End does not certify purity. No health warnings have emerged for swimwear in this category.

The full breakdown

What it's made of and why it matters

This swimsuit combines nylon and polyester, both petroleum-derived synthetics chosen for stretch, durability, and quick-dry properties. The chlorine-resistant and water-repellent coating (water-repellent coating) finishes are the concern: chlorine resistance in swimwear is commonly achieved via chemical cross-linking or topical coatings, while water-repellent coating treatments historically rely on PFAS-based repellents to prevent water absorption and extend garment life. Without material disclosure from Lands' End, the specific chemistry of these finishes remains unknown.

The brand's record and disclosure

Lands' End does not publicly disclose the chemical composition of water-repellent coating or chlorine-resistant treatments on product pages or sustainability reports reviewed in available sources. The brand has not achieved third-party certifications (e.g., Bluesign, OEKO-TEX) that would independently verify absence of restricted chemicals. No recalls or public safety alerts specific to this product line are on record, but silence on PFAS use is a significant gap for a product marketed as durable and chlorine-resistant.

How it compares in its category

Chlorine-resistant swimwear from mainstream brands (Lands' End, Speedo, TYR) rarely disclose water-repellent coating or finish chemistry, making this product typical of the category rather than an outlier. Eco-certified alternatives (e.g., Patagonia Recycled Nylon, some Speedo Eco lines) often state non-PFAS water-repellent coating or omit the finish entirely. This Lands' End suit sits in the middle: reputable brand, no independent verification, and standard market opacity on chemical treatments.

If you buy it

Rinse immediately after chlorinated water use and wash in cool water without fabric softener, which can degrade water-repellent coating coatings and may trap leached chemicals. Avoid high heat (dryer, direct sunlight for extended periods) as synthetic blends can degrade and potentially release residual treatment chemicals. Replace every 1-2 years if worn regularly in pools; water-repellent coating finishes degrade with laundering and UV exposure. Contact Lands' End customer service directly to request written confirmation of water-repellent coating/chlorine-resistant treatment chemistry; their response will clarify whether PFAS are used.
