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 residual dye chemicals
Polyester knits are typically dyed with azo or reactive dyes. Reebok does not disclose dye chemistry or restricted substance testing for this specific product, and no recalls are on record; however, residual unreacted dye can persist on unwashed garments and contact skin.
Formaldehyde / VOCs
Cotton-polyester blends are sometimes treated with formaldehyde-based wrinkle-resistant finishes to improve dimensional stability. Reebok's product specifications do not confirm or exclude such treatments; standard athletic wear typically uses lower formaldehyde levels than dress shirts, but pre-wash testing is not disclosed.
Source, ATSDR ↗Microplastic shedding during washing
Polyester garments shed microfibers during machine washing, a known environmental concern rather than direct wearer hazard. This product will shed like typical polyester blends; mitigation requires use of a microfiber catch filter or washing bag, not a brand-specific issue.
Heavy metals
Dark colors in polyester may use pigments containing trace cadmium or lead, though most major brands have reduced these since the 2010s. Reebok does not publish heavy metal testing results; dermal absorption during wear is considered low risk, but repeated skin contact with unwashed dark garments carries theoretical exposure.
Source, FDA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Antimony in polyester
Antimony trioxide is used as a catalyst in polyester synthesis and can leach in trace amounts. No specific testing or incidents reported for Reebok training wear; typical polyester apparel contains very low residual antimony, and dermal exposure during normal wear is considered negligible by textile safety standards.
The full breakdown
What it's made of and why it matters
This shirt is a polyester-cotton blend knit, a standard construction for athletic training wear. Polyester provides durability and moisture-wicking; cotton adds breathability and comfort. The blend itself poses no inherent chemical hazard at wear, though both fibers are processed with dyes and finishing agents during manufacture. No specialty water-repellent or stain-resistant coating is indicated on this product, which eliminates a major source of intentional PFAS or other problematic treatments in athletic apparel.
The brand's record and disclosure
Reebok (owned by Authentic Brands Group as of 2022) does not publicly disclose detailed chemical or PFAS management policies for apparel as standard practice. The brand has faced no major safety recalls specific to formaldehyde, azo dyes, or heavy metals in recent training wear. Industry disclosure on this product line is minimal, but absence of reported incidents in this category suggests compliance with basic U.S. and EU textile safety standards.
How it compares in its category
Standard polyester-cotton athletic tees are among the lowest-hazard clothing items available. This product sits in the mainstream market segment without specialty finishes, making it comparable to typical gym wear from Nike, Adidas, or Target athletic lines. No notable safety advantages or disadvantages relative to peers; the main variable across brands is manufacturing process transparency rather than inherent material risk.
If you buy it
Wash in warm water before first wear to remove residual dyes and finishes. Machine wash in cold water thereafter to preserve color and reduce microfiber shedding during wear and laundering. Do not use bleach or fabric softener, which can degrade polyester and increase release of additives. Replace when elastic degrades or pilling is severe, typically after 50-100 washes depending on care; this is a wear-life issue, not a safety trigger.
