Alo Yoga Alosoft Ribbed Shimmer Pliet Bodysuit Asymmetrical Swimsuit
Lower concern. No typical PFAS triggers in standard swimwear, but shimmer finish unspecified.
This nylon-spandex swimsuit has a shimmer effect likely from mica or polyester coating. No known PFAS-prone features like water-repellent coating or nonstick finish are standard in swimwear. Alo Yoga makes no PFAS claims and no independent lab data is available.

What Alo Yoga Alosoft Ribbed Shimmer Pliet is made of, ingredients and materials
This bodysuit is constructed from nylon and spandex (elastane), a standard high-performance blend for swimwear that resists chlorine and saltwater degradation better than most synthetics. The shimmer finish is not chemically specified by Alo Yoga; it is likely applied mica coating or polyester microfiber rather than a chemical topcoat, which reduces leaching risk during wear. Nylon itself does not leach problematic chemicals under normal swimming conditions, and spandex's synthetic polymer backbone is stable in aquatic environments. The asymmetrical cut and ribbed texture are structural design features with no safety implication.
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.
Antimony in polyester (if present in shimmer coating)
If the shimmer finish includes polyester microfiber, antimony oxide catalysts may be present in trace amounts; no testing results are available for this product. Skin contact with polyester in normal swimming poses negligible absorption risk for this element.
Microplastic shedding from degraded fibers
Over time, chlorine, salt, sun exposure, and wear cause nylon and spandex fibers to degrade and shed microfibers into water. This is a property of all synthetic swimwear materials, not specific to Alo Yoga, and replacement every 1-2 years minimizes cumulative release.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Azo dyes in synthetic fabrics
No specific azo dye content or restricted substance testing has been publicly disclosed for this product. Standard nylon and spandex swimwear generally uses disperse dyes that comply with REACH and CPSIA limits, but Alo Yoga does not verify this for individual items.
Formaldehyde / VOCs
Spandex fibers sometimes use formaldehyde-releasing dyes or elasticizing agents during manufacturing; no residual formaldehyde testing has been published for Alo Yoga products. EU and US textile regulations limit extractable formaldehyde, and spandex swimwear is not a recognized source of concern in consumer monitoring.
Source, ATSDR ↗Fragrance or sensitizer residues from dyeing or finishing
Alo Yoga does not list fragrance or allergen finishes on this product, and no skin reaction reports are documented. Nylon and spandex themselves do not typically release volatile compounds during wear.
The full breakdown
The brand's record and disclosure
Alo Yoga has not published detailed material safety testing results or sustainability certifications for this specific product line, and the brand maintains silence on PFAS use in manufacturing or water repellency treatments. The brand is known primarily for lifestyle positioning and aesthetic marketing rather than transparent chemical disclosure. No recalls, contamination incidents, or formal safety complaints have been publicly documented for Alo Yoga swimwear. The brand's lack of proactive disclosure does not indicate hazard presence, but reflects the broader swimwear industry norm of minimal third-party verification.
How it compares in its category
Most mainstream swimwear (Speedo, Rip Curl, Nike) uses identical nylon-spandex blends without documented chemical hazards; Alo Yoga's material choice is conventional, not premium or budget-edge. Luxury competitors (Eres, Heidi Klein) likewise do not publish superiority data on chemical safety for comparable products. Eco-certified alternatives (Patagonia, Girlfriend Collective) offer recycled nylon and third-party certifications, which provide additional assurance if that matters to you, but Alo's standard materials are not known to be riskier. The shimmer finish is cosmetic; most competitors offer similar finishes with equivalent specification gaps.
If you buy it
Rinse thoroughly in fresh water after each salt or chlorine exposure to remove residual oxidizers and salts that can degrade fibers and any surface coatings. Avoid prolonged sun exposure when not wearing (UV degrades spandex) and store dry in a cool place; do not tumble dry. Replace when elasticity noticeably declines (typically 1-2 years of regular use) or when seams show separation. Hand wash in cool water with mild detergent; machine wash on delicate is acceptable if needed, but will shorten lifespan.
