What Splits59 Women's Sprint High Waist Rigor is made of, ingredients and materials
Splits59 Sprint leggings are nylon-blend fabric with a water-repellent coating (water-repellent coating) finish. The water-repellent coating is the source of the documented PFAS concern. Beyond PFAS, nylon itself is stable in normal wear but can shed microfibers during washing, particularly in a high-friction garment like leggings. The blend composition is not publicly detailed, so exact fiber ratios are unknown.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
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.
PFAS
Water-repellent finish on nylon activewear typically contains PFAS compounds. Splits59 does not disclose coating chemistry. PFAS can leach into skin contact and bioaccumulate; migration risk increases with washing and wear.
Source, ATSDR ↗Microfiber shedding
Nylon-blend leggings shed microfibers in washing, especially during high-friction wear. This is inherent to synthetic athletic wear. Magnitude is not product-specific but typical for the category; concern is environmental rather than direct health hazard.
Formaldehyde / VOCs
Nylon fabrics may undergo finishing processes involving formaldehyde-based resins for wrinkle resistance or sizing. Splits59 does not publish testing or certifications excluding this. Residual formaldehyde is generally low in finished garments but not ruled out without data.
Source, ATSDR ↗Coating degradation and leachables
As water-repellent coating breaks down with age and washing, small polymer particles and residual chemical components may shed or leach. Nylon itself is stable, but coating durability and breakdown chemistry are not disclosed by the brand.
What’s reassuring
Azo dyes
No recall or testing data implicates Splits59 leggings in azo dye use or banned colorant violations. This is not a known issue for this brand; standard industrial dye chemistry presents lower concern if production meets OEKO-TEX or similar standards, which Splits59 does not claim.
The full breakdown
The brand's record and disclosure
Splits59 has made no public statement about PFAS use, chemical standards, or certifications like OEKO-TEX or bluesign. The brand does not disclose water-repellent coating chemistry or commit to PFAS-free practices on their website. This silence contrasts with competitors who have adopted PFAS-free water-repellent alternatives or provide transparency on coating ingredients. No major recalls or safety violations are on record for this brand in the athletic wear space.
How it compares in its category
Most high-end activewear leggings use water-repellent coating finishes, and many still rely on PFAS-based chemistry because alternatives are more expensive. Splits59 is positioned as premium contemporary athletic wear, not as eco-certified or transparency-focused. Brands like Patagonia and Allbirds have moved toward PFAS-free or disclosed alternatives; Splits59 does not highlight such commitments, placing it in the mainstream risk category for this hazard.
If you buy it
Wash in cold water and use gentle cycles to minimize water-repellent coating migration and microfiber shedding. Avoid heat (tumble dry, high iron) which may accelerate coating breakdown and off-gassing. Replace when water-repellent coating visibly deteriorates or elastic weakens. If PFAS exposure is a personal priority, consider requesting material testing from the brand or selecting alternatives with transparent PFAS-free certifications.
