PUMA Men's Cloudspun Training T-Shirt
Lower concern, no water or stain treatment typical for this knit.
Cloudspun is a polyester blend without disclosed water-resistant or stain treatments. Puma makes no PFAS claims, and standard knit training tees rarely contain PFAS, though brand transparency is absent.

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.
Azo dyes and dye-related allergens
Reactive dyes used in polyester textiles may contain azo compounds; no specific information on Cloudspun dye chemistry is publicly available. Some individuals with sensitive skin may react to residual dye or unfixed chromophores, though this is rare with modern industrial dyeing.
Microplastic shedding
All synthetic textiles shed microfibers during washing; polyester blends are moderate shedders. This is an environmental rather than direct health hazard, though inhaled synthetic dust poses low occupational risk to manufacturing workers, not consumers.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Training knits typically do not receive wrinkle-resist or durable-press finishes that require formaldehyde resin binders. No public evidence that Cloudspun includes formaldehyde-releasing treatments.
Source, ATSDR ↗Antimony in polyester
Antimony is a catalyst used in polyester synthesis; trace residues (typically <0.1%) are present in all polyester fibers. Leaching during wear or washing is negligible and not documented as a health concern for consumer textiles.
Flame retardants
No flame-retardant finish is stated or typical for athletic training tees. Polyester itself has moderate inherent flame resistance and does not require chemical flame retardants for apparel use.

What it's made of and why it matters
Cloudspun is Puma's proprietary polyester-blend knit fabric, typically a mix of polyester with elastane or nylon for stretch. Polyester fibers themselves do not leach chemicals during normal wear or washing; the hazard profile depends entirely on dyes, finishing treatments, and any coatings applied. For an uncoated training tee with no water-repellent or flame-retardant finish claimed, the chemical load is primarily from reactive dyes and residual processing chemicals, not the polymer base.
The brand's record and disclosure
Puma has not published detailed PFAS or restricted substance policies specific to individual garment lines. The brand is a signatory to the Sustainable Apparel Coalition's Higg Index and has committed to some restricted substance limits, but transparency on formaldehyde resins, azo dyes, or antimony in polyester for this particular product is absent from public records. No recalls or reported chemical safety incidents tied to Cloudspun fabric are documented.
How it compares in its category
Uncoated polyester training wear is one of the lowest-risk garment categories because it avoids water-repellent coatings (common PFAS source) and heavy-duty finishes. This product sits in the mainstream athletic apparel safety band; equivalent offerings from Nike, Adidas, and New Balance carry similar hazard profiles and disclosure gaps. Certification to bluesign(R) or GOTS would elevate confidence, but standard athletic polyester knits rarely achieve that.
If you buy it
Wash before first wear to remove residual dyes and processing chemicals. Use warm water (not hot) and mild detergent; polyester is not damaged by heat but warm water is sufficient. Avoid fabric softeners and bleach, which can degrade elastane and are unnecessary. Replace when elastic waistband or seams fail; the fabric itself does not degrade or off-gas with age under normal conditions.
