Koral Drive High-Rise Energy Legging
Moisture-wicking apparel; unclear if water-repellent coating contains PFAS. Request clarification.
Koral does not disclose PFAS presence or absence for this legging. Performance fabrics often use water-repellent coating (water-repellent coating) treatments that may contain PFAS. Direct contact with the brand is recommended for material confirmation.

What Koral Drive High-Rise Energy Legging is made of, ingredients and materials
Koral Drive leggings are nylon blend with a moisture-wicking finish, which typically involves chemical treatments to repel sweat and speed drying. Nylon itself is stable synthetic fiber, but the added finish is the concern, moisture-wicking often relies on either PFAS-based durable water repellents (water-repellent coating) or polyurethane coatings, both of which can leach or degrade with washing. Koral has not publicly disclosed which technology they use, leaving the composition unclear.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.

PFAS
Nylon activewear with moisture-wicking treatment commonly uses PFAS-based water-repellent coating finishes, though some manufacturers now use alternatives. Koral has not disclosed their chemistry, so presence cannot be ruled out. Contact brand for verification.
Source, ATSDR ↗Formaldehyde / VOCs
Nylon finishing processes sometimes employ formaldehyde-based crosslinkers to set moisture-wicking and durability properties. No specific reports exist for Koral products, but the hazard is present in the material class and heightened if finishes are not fully cured at manufacture.
Source, ATSDR ↗Microplastic shedding from synthetic fiber
Nylon leggings shed microfibers during washing. While this is an environmental and ingestion concern rather than a direct wearer hazard, frequent washing will accelerate fiber loss. Use a wash bag or microfiber filter if concerned about waterborne plastic pollution.
Coating degradation and leaching over time
Moisture-wicking finishes degrade with repeated washing and heat exposure. As the coating breaks down, residual uncrosslinked chemicals or particulates may leach into sweat or skin contact. Washing in cool water and air drying slows this process.
What’s reassuring
Azo dyes and synthetic colorants
No specific violations or reports linked to Koral dye safety. However, nylon typically accepts synthetic dyes; if the product is deep black or vivid colors, azo dyes (some of which release carcinogenic amines) may be present. Standard apparel regulations in major markets restrict the most hazardous azo compounds, so risk is low but not eliminated.
How is this PFAS grade calculated?
The brand's record and disclosure
Koral is a premium activewear brand with minimal public disclosure on chemical use or safety testing. The brand has not published PFAS commitments, material sourcing transparency reports, or third-party certifications like bluesign or GOTS. There are no established recalls or safety violations on record for this specific product line, but the silence on ingredient and process detail is a transparency red flag in an industry where major competitors increasingly provide such information.
How it compares in its category
Premium nylon activewear often carries coating-related chemical uncertainty; Koral is typical in this respect. Competitors like Outdoor Voices and Patagonia have moved toward PFAS-free water repellents or transparent disclosure. Koral's lack of public commitment places it in the middle-risk band of the category. If moisture-wicking durability is your priority, this product is competitive; if chemical minimization is, brands with bluesign certification or published claims about not containing intentionally added PFAS represent lower concern options.
If you buy it
Wash in cool to warm water (avoid hot) to minimize coating degradation and any potential leaching from finishes. Air dry to preserve the moisture-wicking treatment and avoid heat exposure that could release volatiles. Replace after 100-150 wears or visible pilling and loss of water resistance. Before purchase, contact Koral directly asking whether the water-repellent coating contains PFAS; a transparent answer supports informed choice.
