Koral Lustrous High-Rise Athletic Leggin - New Women | Color: Blue
Lower concern. Athletic knit typically has no PFAS finish.
Koral makes no PFAS claims for this leggin. Standard nylon blend athletic wear rarely receives water-resistant coatings that contain PFAS, though water-repellent coating treatment is possible without disclosure.

What’s concerning
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Heavy metals
Nylon knits are typically disperse-dyed with azo compounds; some older formulations or budget dye baths may use heavy metal mordants (copper, chrome). Koral does not disclose dye safety standards or restrictions. Risk is low with modern dyeing but unverified for this specific product.
Source: FDA ↗Elastane (spandex) degradation and microfiber shedding
Elastane exposure to heat, chlorine, or harsh detergent can break down and shed microfibers into washwater. This is a mechanical wear issue, not a chemical hazard, but relevant to durability and environmental shedding. Cold water washing and gentle handling mitigate this.
Residual dyes bleeding and skin irritation
Cheap or poorly fixed dyes can leach onto skin during wear or washing, causing irritation in sensitive individuals. Pre-washing in cool water significantly reduces this risk. Koral's mid-tier positioning suggests adequate dye fixation, but no color-fastness testing is disclosed.
What’s reassuring
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Formaldehyde / VOCs
Uncoated athletic knits rarely receive formaldehyde-releasing finishes (those are common in woven shirting and denim). No evidence Koral applies wrinkle-free or stiffening resins to this knit. Standard nylon knit production does not require formaldehyde chemistry.
Source: ATSDR ↗Antimony in polyester or antimicrobial additives
This is a nylon-elastane blend, not polyester, so antimony catalyst residue is not a concern. No indication of antimicrobial silver or copper treatments on record for this product line.
The full breakdown
What it's made of and why it matters
This leggin is a nylon blend athletic knit, likely 82-88% nylon with elastane (spandex) for stretch. Nylon fibers themselves are thermoplastic polyamides with no inherent lead, cadmium, or BPA concerns. The uncoated knit construction means no water-resistant or stain-resistant chemical finish that would introduce durable fluorinated compounds (PFAS), formaldehyde resins, or heavy metal catalysts. The main exposure pathways in athletic wear like this are dye chemistry and finishing agents applied during manufacturing.
The brand's record and disclosure
Koral is a contemporary activewear brand without a published chemical disclosure policy or third-party certifications (BLUESIGN, OEKO-TEX, GOTS) listed in accessible sources. The brand has not publicly acknowledged PFAS use or phased reduction, nor are there documented recalls, safety violations, or chemical exposure incidents on record. The silence on PFAS stance reflects an industry norm among mid-tier athletic brands rather than a red flag, but indicates no proactive transparency commitment.
How it compares in its category
Nylon blend athletic knits are common and relatively low-risk compared to coated leggings (which often contain PFAS) or those with antimicrobial finishes (which may use heavy metals or fluorines). Performance knits from comparable brands like Alo Yoga, Splits59, and Gymshark occupy the same hazard profile. This product has no known edge in safety but also no known deficiency; it sits squarely in mainstream athletic wear risk.
If you buy it
Wash in cool water with mild detergent before first wear to remove residual dyes and finishing agents from manufacturing. Machine wash cold, gentle cycle thereafter; avoid fabric softener and bleach, which can degrade elastane and trigger dye bleeding. Dry flat or on low heat. Replace when elastane loses recovery (visible sagging or pilling) or if color fades unevenly, which signals fiber breakdown. No special precautions beyond standard athletic care are needed.
