Nike Men's Stride Dri-FIT ADV Running Tank Top
Dri-FIT treatment raises concern; Nike provides no PFAS disclosure.
Nike's Dri-FIT is a moisture-wicking finish commonly applied to polyester. Nike provides no public PFAS commitment or testing data.

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
Dri-FIT coating mechanism is not publicly disclosed by Nike; fluorochemicals are common in hydrophobic athletic finishes. No recall or test report on this specific model exists, but the finish category carries unresolved PFAS risk.
Source, ATSDR ↗Microfiber shedding from synthetic blend
All polyester apparel sheds microfibers during washing; the Dri-FIT treatment may alter shedding slightly, but no brand-specific data exists. This is a laundry-system environmental hazard, not a wearer safety hazard.
What’s reassuring
Antimony in polyester fiber
Polyester production may involve antimony as a catalyst, but contamination at consumer-detectable levels in finished apparel is not a documented issue for Nike products or this category.
Azo dyes (color fastness concerns)
Nike uses restricted azo dyes in most mainstream apparel and tests for compliance; no specific recalls or warnings documented for Dri-FIT tank colorants. Standard polyester dyes are stable in wear and washing.
Formaldehyde / VOCs
Dri-FIT is a hydrophobic finish, not a wrinkle-resist resin; formaldehyde-based finishes are not typical in this treatment class. No documented formaldehyde release from Nike athletic apparel.

What it's made of and why it matters
This tank is polyester blend with Nike's proprietary Dri-FIT moisture-wicking treatment applied to the fabric surface. Dri-FIT technology typically involves fluorochemical coatings or hydrophobic finishes that repel sweat, and Nike has not publicly disclosed whether PFAS compounds are part of this formulation. Polyester itself is stable and does not leach chemicals during normal wear, but the applied finish is the unknown variable here.
The brand's record and disclosure
Nike has faced public pressure on PFAS transparency but has not published a comprehensive chemical disclosure policy for apparel treatments as of recent public record. The company has made commitments to reduce certain hazardous chemicals but remains silent on PFAS use in Dri-FIT and similar performance coatings across its lineup. This lack of disclosure is a material gap in consumer trust for a premium product at this price point.
How it compares in its category
Most high-performance athletic tanks from major brands (Adidas, Under Armour, Lululemon) use similar chemical finishes without public PFAS disclosure, making this a category-wide problem rather than Nike-specific. However, brands like Patagonia and some smaller athletic makers have committed to PFAS-free moisture management. If PFAS avoidance is a priority, this product sits in the higher-risk tier of mainstream performance apparel.
If you buy it
Wash in cool or warm water (not hot) before first wear to reduce potential leaching of residual finish chemicals. Machine wash on gentle cycle with mild detergent; avoid chlorine bleach which can degrade polyester. Do not tumble dry on high heat, as elevated temperature may weaken the Dri-FIT coating. If Nike publishes PFAS test results or commits to PFAS-free formulations, reassess your purchase decisions on future replacements.
