Zella Live In High Waist Leggings in Black at Nordstrom, Size Xx-Small
Lower PFAS concern. Zella silent on water-repellent coating treatment specifics.
Zella leggings are nylon-spandex stretch activewear with no disclosed water-repellent finish. No PFAS claim or third-party verification available; standard athletic knits carry lower inherent risk than treated performance fabrics.

What Zella Live In High Waist Leggings is made of, ingredients and materials
Zella Live In leggings are nylon-spandex (elastane) blended fabric, a common synthetic athletic wear composition. Nylon itself is inert when worn and does not off-gas volatile compounds under normal use conditions. Spandex adds stretch and recovery without introducing known acute chemical hazards at the fiber stage. The dye system and any finishes applied during manufacturing are where residual chemical risk concentrates, but nylon dyeing typically uses acid or disperse dyes rather than the most problematic azo chemistry.
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 is typically dyed with acid or disperse dyes, which include azo chemistry in some formulations. Restricted azo dyes (those cleaving to carcinogenic amines) are banned in many countries, but non-restricted azo dyes remain in use. No specific testing data is available for this product; residual dye on fabric is minimal after manufacture but present on unwashed goods. Wash before first wear to
Source, FDA ↗Spandex degradation and microfiber shedding
Spandex fibers can degrade over time and with improper care (high heat, chlorine, abrasion), releasing microfibers into wash water. This is not a chemical toxicity hazard per se but an environmental and potential inhalation concern during extended use. Cool washing and air drying minimize this risk. Replacement after visible elastic loss is a practical mitigation.
Dye transfer and color bleeding onto skin
Black nylon leggings from retail brands may bleed dye, especially on initial wears or if washed in hot water with light fabrics. This is primarily a staining concern rather than a toxicity issue, as ingested dye is minimal. Unwashed exposure to residual dye on new garments is the main pathway. Washing before first wear eliminates most risk.
What’s reassuring
Base material not linked to PFAS
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Formaldehyde / VOCs
Athletic leggings typically do not receive formaldehyde-based durable press treatments, which are more common in dress shirts and cottons. Nylon naturally resists wrinkles. No evidence suggests Zella applies formaldehyde resins to this product, and no recalls or complaints document this hazard for the brand.

This product is nylon-spandex, not polyester, so antimony catalysts are not relevant. Antimony is a concern for polyester textiles, not this material class.
The full breakdown
The brand's record and disclosure
Zella is a Nordstrom house brand with no published material disclosures, third-party certifications (such as OEKO-TEX or bluesign), or documented chemical safety commitments on record. The brand does not publicly detail dye sourcing, finish treatments, or heavy metal testing. No major product recalls or chemical controversies have been documented for Zella apparel. Transparency is limited, but this reflects typical retail house-brand practices rather than flagged misconduct.
How it compares in its category
Nylon-spandex athletic leggings are a mainstream category choice; this material pairing is used across brands from budget to premium tiers. Zella sits in the mid-market segment without claimed sustainability or ethical sourcing differentiators. Certified alternatives (OEKO-TEX, Fair Trade, organic cotton blends) exist but cost more and are less common in this format. For a standard retail athletic garment, Zella's material composition and manufacturing opacity are unremarkable.
If you buy it
Wash in cool water and avoid high heat dryers, which can degrade spandex elasticity and theoretically accelerate any finish breakdown. Turn inside out before washing to minimize pilling and dye loss. Do not bleach. Expect the garment to last 50 to 100 wears with proper care before spandex loses significant recovery. If seams fray, elasticity visibly degrades, or fit becomes unsafe, retire the item; this is a longevity signal, not a chemical hazard trigger.
