PUMA Men's Run Coolcell Cooling Running T-Shirt
Lower concern, but Puma provides no PFAS transparency on moisture-wicking tech.
Running shirts with moisture-wicking typically use polyester. Puma doesn't disclose whether their Coolcell treatment involves PFAS, making full risk assessment difficult. Cotton blend options may reduce uncertainty.

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.
Formaldehyde / VOCs
Moisture-wicking treatments sometimes use formaldehyde-based crosslinkers to bond hydrophobic coatings to polyester. Puma does not disclose whether Coolcell uses this method; residual formaldehyde (if present) would off-gas minimally during wear or washing but could trigger contact dermatitis in sensitive individuals.
Source, ATSDR ↗Heavy metals
Polyester athletic wear is typically dyed with disperse or vat dyes; restricted azo dyes (those producing carcinogenic amines) are banned in EU markets and most quality brands follow this standard. Puma does not publish dye test certifications, so risk level cannot be ruled below possible.
Source, FDA ↗Antimony in polyester fiber
Polyester is synthesized using antimony trioxide as a catalyst; residual antimony in the finished fiber is typically <0.5% and not classified as a skin hazard during normal wear. No published studies link antimony migration from polyester apparel to health effects, but the hazard exists at trace levels.
Microfiber shedding during washing
All synthetic fibers, including polyester, shed microfibers during machine washing. This is an environmental hazard (aquatic pollution) rather than a direct wearer health risk, but it is well-documented. Washing in cold water and using a microfiber catch bag reduces shedding by up to 30%.
Skin irritation from residual finish chemicals
Untreated polyester blend apparel with fresh moisture-wicking finishes can cause itch or mild contact dermatitis in people with sensitive skin. One wash-and-dry cycle removes most surface residue; sensitivity typically resolves after 2-3 wears.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
The full breakdown
What it's made of and why it matters
This shirt is a polyester blend engineered with a moisture-wicking treatment to pull sweat away from skin during running. Polyester itself is a synthetic polymer with a stable molecular structure, meaning it does not naturally leach harmful chemicals into skin during normal wear. The 'Coolcell' treatment is a finishing process applied to the fabric surface, likely a polymer-based hydrophobic coating; the exact chemical composition is proprietary and not disclosed by Puma, which is standard industry practice but limits transparency.
The brand's record and disclosure
Puma has not published detailed ingredient transparency or PFAS policies for apparel moisture-wicking treatments, which is a gap compared to some competitors like Patagonia. The brand has signed the Apparel Impact Institute commitment to reduce chemical hazards but does not routinely disclose third-party test results for finished garments. No major recalls or contamination incidents are on record for Puma athletic tops.
How it compares in its category
Performance athletic wear universally uses polyester blends and finish treatments; Puma's approach is typical for mid-to-premium brands. Competitors like Nike and adidas maintain similar opacity around moisture-wicking chemistry. Organic cotton or recycled polyester alternatives exist but are less common in high-performance running wear and carry their own trade-offs (durability, moisture management).
If you buy it
Wash in cool or warm water (not hot) before first wear to reduce potential residual finish chemicals. Machine wash with mild detergent; avoid bleach and fabric softener, which can degrade the moisture-wicking treatment. Polyester does not require special drying. Replace if seams fray, elastic loses function, or fabric pilling becomes visible, which signals fiber breakdown and reduced performance.
