What Nike Men's Repel Miler Running Jacket is made of, ingredients and materials
This jacket is polyester with a water-repellent coating (water-repellent coating) finish. water-repellent coating coatings on athletic apparel have historically relied on PFAS-based chemistry, though some brands have shifted to PFAS-free alternatives. Nike has not publicly disclosed whether this Repel Miler uses legacy PFAS compounds or newer PFAS-free formulations. Polyester itself is a synthetic polymer with a low direct toxicity profile but can release microfibers during washing and wear.
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.
Formaldehyde / VOCs
Water-repellent coating finishes sometimes incorporate formaldehyde-releasing resins as crosslinkers. Nike does not disclose whether this jacket uses such chemistry. Off-gassing risk is minimal after initial manufacture and washing but cannot be ruled out without material data.
Source, ATSDR ↗Microfiber shedding during wash and wear
Polyester garments, especially those with coatings, release microfibers during laundering. This is an environmental rather than direct health hazard but is well-established for synthetic athletic wear and worsens with mechanical washing.
water-repellent coating degradation and inhalation
As water-repellent coating finishes break down with use and washing, aerosolized particles may be shed. If the coating contains PFAS, this represents a secondary exposure route. Nike's silence on water-repellent coating chemistry prevents assessment of this specific risk.
What’s reassuring
Azo dyes and colorfast integrity
No recalls or published testing indicate azo dye toxicity in this model. Polyester dyes in athletic wear are typically azo-free or low-risk, but no independent verification for this specific product is on record.
Antimony in polyester
Antimony is used as a polyester catalyst in production and can remain as trace residue. No brand-specific data or health incident reports exist for Nike apparel; levels are typically below regulatory concern in finished garments.
How is this PFAS grade calculated?
The brand's record and disclosure
Nike has made limited public commitments on PFAS phase-out across its apparel line and has not released a comprehensive inventory of which products contain PFAS-based water-repellent coating. The company has not provided test reports or third-party certifications for this specific jacket. Nike's environmental reporting does not routinely disclose water-repellent coating chemistry. This lack of transparency makes it difficult to assess the actual PFAS exposure risk of this product.
How it compares in its category
Running jackets with water-repellent finishes are common, and most major brands face the same water-repellent coating disclosure gap. Some competitors (Patagonia, Arc'teryx) have publicly committed to PFAS-free water-repellent coating or disclosed testing; others including Nike remain silent. If PFAS-free water-repellent coating is your priority, this jacket offers no assurance over alternatives unless you contact Nike directly for material safety data.
If you buy it
Wash in cool water and avoid high heat drying, which can stress synthetic fibers and potentially accelerate water-repellent coating breakdown. Expect the water-repellent finish to diminish after 30-50 washes regardless of PFAS status. Do not expose to flame or direct heat sources. If water-repellent coating treatment toxicity is a concern, contact Nike customer service to request technical data on this specific product batch before purchase.
