Lands' End Women's Tugless X-Back One Piece Swimsuit
Avoid unless Lands' End discloses water-repellent coating chemistry; swimsuit water-repellency historically depends on PFAS.
Lands' End does not publicly disclose the water-repellent treatment chemistry used in this tugless swimsuit. Modern swimwear durability often depends on water-repellent coating coatings, which traditionally used PFAS compounds, leaving PFAS risk unresolved without transparency or testing.

Brand is silent on 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.
water-repellent coating chemistry (unspecified)
Lands' End does not disclose whether the water-repellent finish uses PFAS or PFAS-free alternatives. Historical nylon swimwear water-repellent coating finishes relied on long-chain PFAS; newer formulations may use shorter-chain or non-fluorinated options, but no public statement confirms which this product contains. Skin contact with the finish is minimal but prolonged wet wear could increase migration risk.
Nylon degradation and leaching from chlorine/salt
Nylon fibers break down when exposed to chlorine and salt water, releasing microscopic particles and potentially mobilizing any residual fabric dyes or finish components. This is not a manufacturing defect but inherent to the material; well-documented in swimwear testing. Rinsing immediately after pool/ocean use reduces this risk.
Spandex UV and chlorine sensitivity
Spandex (elastane) loses elasticity and may degrade into smaller oligomers when exposed to UV light, chlorine, and saltwater. This is well-established in textile literature and affects all swimwear blends. Shade drying and prompt rinsing mitigate but do not eliminate the effect.
Microfiber shedding during laundering
All synthetic swimwear sheds microfibers when washed. Nylon microfiber shedding is lower than polyester but still occurs, especially as the garment ages. Hand washing or a mesh bag reduces shedding compared to machine washing.
What’s reassuring
Azo dyes or other colorants (unconfirmed)
Lands' End does not publish dye or colorant sourcing for this swimsuit. Nylon readily accepts acid dyes; no specific safety incident or recall implicates this product. OEKO-TEX certification would confirm restricted substance limits, but Lands' End does not seek this for swimwear lines.
The full breakdown
What it's made of and why it matters
This swimsuit is a nylon-spandex blend, likely 80/20 or similar ratio. Nylon is a synthetic polyamide that is chemically stable in normal use but relies on a water-repellent coating (water-repellent coating) finish applied to the fabric surface to maintain water shedding. water-repellent coating coatings historically used long-chain PFAS compounds; modern alternatives exist but are not standard across the industry. The spandex component is prone to degradation from UV exposure, chlorine, and salt water, which is separate from any chemical leaching risk.
The brand's record and disclosure
Lands' End does not publicly disclose the chemistry of its water-repellent coating finish on this product or state whether it uses PFAS-free alternatives. The brand has no published PFAS commitment or chemical transparency policy on record. No specific recalls or safety warnings for this swimsuit model are documented. The absence of third-party certifications (such as OEKO-TEX or bluesign) leaves the chemical composition unverified by independent labs.
How it compares in its category
Most mainstream swimsuit brands (Speedo, Nike, Target athleisure lines) do not disclose water-repellent coating chemistry either, making this product typical rather than exceptional in transparency. Some premium and eco-focused brands (Patagonia, Girlfriend Collective) have moved toward PFAS-free water-repellent coating or openly state their approach. Lands' End occupies the middle market, where chemical disclosure lags behind sustainability-first competitors. The tugless and x-back design are durability and comfort features unrelated to chemical safety.
If you buy it
Rinse thoroughly after each use in chlorinated pools or salt water to reduce spandex degradation and remove residual chemicals. Air dry in shade, not direct sunlight, to preserve elasticity. Expect the water-repellent finish to fade after 20-40 washes, at which point the suit is still wearable but less water-shedding. Do not machine wash on hot or use fabric softener, which accelerates spandex breakdown and may strip any water-repellent coating. Replace when the elastic loses recovery or seams show stress.
