Lower concern; untreated knit fabric unlikely to use water-repellent coating.
Nylon-elastane CloudKnit blend with no known water-resistant or stain-resistant finish marketed. Untreated stretch fabrics typically carry minimal PFAS risk.

What OUTDOOR VOICES CLOUDKNIT Online Only is made of, ingredients and materials
Outdoor Voices CloudKnit leggings are a nylon-elastane (spandex) blend, a common high-performance textile for activewear. Nylon itself is a synthetic polyamide with a stable chemical structure once manufactured. The elastane component provides stretch and recovery; both materials are well-established in athletic apparel with decades of use data. The light blue color requires dyes, which is the primary chemical concern in this product category.
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.
Azo dyes and dye-related contact sensitization
Light blue synthetic dyes in nylon require chemical coloring; azo dyes (regulated in EU but not comprehensively in the US) are a concern in untested athletic apparel. Outdoor Voices does not disclose dye chemistry or publish OEKO-TEX certification for this line, so azo status is unknown.
Formaldehyde / VOCs
Nylon textiles often use formaldehyde-based resins to improve wrinkle resistance, water repellency, or shape retention during finishing. No testing or certification data is public for CloudKnit, so residual formaldehyde cannot be ruled out, particularly in manufacturing countries with fewer restrictions.
Source, ATSDR ↗Elastane (spandex) degradation and microfiber shedding
All nylon-elastane blends shed microfibers with wear and washing. Elastane itself is not acutely toxic, but microfiber pollution is an environmental concern; synthetic microplastics are detected in marine ecosystems and aquatic organisms. This is a category-wide issue, not specific to Outdoor Voices.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Light blue dyes may use metal-complex colorants (chromium, cobalt, or nickel compounds) in trace amounts; these are regulated in apparel textiles but not independently tested for this product. No recalls or reports exist for Outdoor Voices apparel.
Source, FDA ↗PFAS
CloudKnit is an untreated knit fabric without an explicit water-repellent topcoat, making it unlikely to contain legacy water-repellent coating treatments (PFOA, Teflon-type coating-based coatings). However, Outdoor Voices does not confirm this in writing, leaving a small window of uncertainty.

The brand's record and disclosure
Outdoor Voices has not published detailed chemical disclosure statements, supply-chain certifications (OEKO-TEX, Bluesign), or testing reports accessible to consumers. The brand does not maintain a public stance on PFAS use in finishes. No recalls, safety violations, or chemical contamination incidents are documented for Outdoor Voices apparel. This silence on disclosure is typical for mid-tier athletic brands but leaves some uncertainty around dye standards and finishing processes.
How it compares in its category
Nylon-elastane leggings dominate the yoga and athletic market; this material combination is standard across Lululemon, Athleta, and Nike. Outdoor Voices positions itself at a lower price point than Lululemon, with less public certification data. Brands like Patagonia and Allbirds offer similar products with published OEKO-TEX or similar certifications, giving them a transparency advantage. The CloudKnit fabric itself is proprietary and not independently tested for chemical content.
If you buy it
Wash new leggings in cold water before first wear to reduce potential residual dyes or finishes. Machine wash in cool water, avoid hot dryers (heat can degrade elastane and any coatings), and air-dry when possible. Inspect seams and fabric after 50+ wears for pilling or thinning, which signals elastane breakdown. If you develop skin irritation, sensitivity, or color transfer, discontinue use; this could indicate dye instability or formaldehyde-based finishes used in manufacturing.
