What Hoka Men's Novafly Run Tights is made of, ingredients and materials
Hoka Novafly Run Tights are constructed from a nylon blend, a synthetic polymer chosen for stretch, durability, and moisture management in athletic wear. The water-repellent coating (water-repellent coating) finish applied to the fabric is the key concern, water-repellent coating coatings on apparel are historically treated with fluorinated compounds (PFAS) to repel moisture while maintaining breathability. Hoka does not publicly disclose whether this product uses PFAS-based or alternative water-repellent coating chemistry, which is the primary unknown for this item.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Nylon tights with water-repellent coating finish commonly use fluorinated compounds; Hoka does not disclose chemistry, so PFAS presence cannot be ruled out. Skin contact with treated fabric is a low-level exposure route for apparel, but cumulative laundry water discharge poses broader environmental concern.
Source, ATSDR ↗Microplastic shedding
Like all synthetic nylon apparel, these tights shed microfibers during washing. The amount is typical for the material class, not exceptional to this brand, but accumulates with repeated laundering over the product lifetime.
What’s reassuring
Azo dyes
No public records indicate Hoka uses prohibited azo dyes in this product or other tights. Most reputable brands in this tier avoid them, but explicit third-party certification (OEKO-TEX, Bluesign) is absent from Hoka's marketing.
Formaldehyde / VOCs
Formaldehyde-based curing agents are not typical in water-repellent coating or stretch nylon apparel; modern finishes in this category do not rely on formaldehyde. This hazard is unlikely but not formally ruled out by Hoka documentation.
Source, ATSDR ↗Antimony in polyester (if blend includes polyester)
Product is described as nylon blend; if polyester is a minor component, antimony catalyst residue is theoretically possible but unlikely and undocumented. Hoka does not specify the exact fiber composition beyond 'nylon blend.'
How is this PFAS grade calculated?
The brand's record and disclosure
Hoka has not published a clear PFAS policy or chemical disclosure statement for its apparel lines as of available records. The brand is known for performance footwear innovation but lags behind leaders like Patagonia and The North Face in transparency around fluorinated treatments. No recalls or substantiated safety controversies specific to Hoka tights have been documented in public databases. Without proactive communication on water-repellent coating chemistry, consumers cannot assess PFAS risk at the point of purchase.
How it compares in its category
Most performance running tights in the mid-to-premium tier receive water-repellent coating treatment, making untreated alternatives rare. Brands like Nike, Lululemon, and Allbirds have begun transitioning to PFAS-free or disclosed water-repellent coating systems, though disclosure remains inconsistent across the category. Hoka tights are competitively priced and well-reviewed for fit and durability, but the silence on chemical inputs puts them behind category leaders on environmental and health transparency. If PFAS avoidance is a priority, seeking brands with explicit PFAS-free claims is advisable.
If you buy it
Wash in cold water and avoid fabric softeners, which can degrade water-repellent coating performance and release microfibers. Do not use high heat (tumble dry or direct sunlight) as nylon can soften above 75-80 degrees Celsius, compromising fit and durability. Replace when elasticity visibly decreases or seams show wear, typically 12-24 months of regular wear. If water-repellent coating performance matters to you, contact Hoka customer service directly to request confirmation of their water-repellent coating treatment chemistry before purchasing.
