What Nike Men's AeroSwift Dri-FIT Running Top is made of, ingredients and materials
This is a polyester-blend athletic shirt with Dri-FIT moisture-wicking technology and a likely fluorocarbon-based water-repellent coating (water-repellent coating) finish. Polyester itself is stable when worn, but the water-repellent coating applied to achieve water resistance is commonly treated with PFAS "forever chemicals" (PFAS), which do not break down in the body or environment. The Dri-FIT system typically involves synthetic polymer treatments that may include formaldehyde-release resins used to set the fiber structure and improve durability.
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
Polyester athletic tops with water-resistant finishes are routinely treated with fluorocarbon compounds. Nike does not disclose whether this product uses legacy PFOS/PFOA or newer short-chain alternatives; both persist in the body and environment. Direct skin absorption during wear is low, but laundry effluent is a known exposure pathway.
Source, ATSDR ↗Formaldehyde / VOCs
Polyester fabrics often use formaldehyde-based cross-linkers to set Dri-FIT polymer coatings and improve wrinkle resistance. Off-gassing is typically minimal after a few wash cycles, but sensitive individuals may experience irritation with unwashed garments. No specific testing data for this product is available.
Source, ATSDR ↗Microplastic Shedding
Synthetic polyester blends shed microfibers during washing, particularly in early wash cycles and with degradation over time. This is an environmental concern rather than a direct consumer-health hazard, but fibers enter waterways and food chains.
What’s reassuring
Heavy metals
Nike apparel is not known to use restricted azo dyes or heavy metals in colorants, and the brand maintains dyeing standards consistent with major sports apparel manufacturers. No recalls or contamination reports specific to this product exist.
Source, FDA ↗Antimony in Polyester Fiber
Antimony trioxide is used as a catalyst in polyester production but remains bound within the polymer chain during wear. Migration to skin or sweat is not documented as a significant health concern under normal use, and no regulatory warnings apply to polyester apparel.
How is this PFAS grade calculated?
The brand's record and disclosure
Nike has not publicly disclosed PFAS use in Dri-FIT products or water-repellent coating treatments, despite growing industry scrutiny. The company has faced criticism from environmental advocates for lack of transparency on per- and polyfluoroalkyl chemical use across its apparel lines. Nike has committed to sustainability goals but has not published specific PFAS phase-out timelines or alternatives being tested. No major recalls or safety violations specific to formaldehyde or heavy-metal contamination in Dri-FIT apparel are on record.
How it compares in its category
Performance running tops with synthetic moisture-wicking finishes across major brands (Nike, Adidas, Under Armour, On) typically use water-repellent coating and similar polymer treatments without public disclosure of PFAS content. Polyester-blend athletic wear is standard, but the water-repellent coating finish is a material linked to PFAS concern. Natural-fiber alternatives (merino wool, organic cotton blends) or synthetic fabrics with water repellent options not linked to PFAS exist but are less common at this price and performance tier. Nike's silence on water-repellent coating chemistry is consistent with industry-wide opacity on this issue.
If you buy it
Wash new garments separately before first wear to reduce exposure to any residual treatments or dyes. Use cool or lukewarm water and avoid high-heat drying, which can degrade the water-repellent coating finish and potentially increase fiber shedding. Replace when elasticity fails, seams fray, or water repellence is visibly lost, typically after 50-100 wash cycles for performance fabrics. Do not dry-clean, as solvents may interact unpredictably with the water-repellent coating and residual treatment chemicals.
