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 color fastness
The printed graphic uses dyes and pigment binders whose formulation Brooks does not disclose. Azo dyes are regulated but some variants can release aromatic amines under specific conditions (prolonged sweat, abrasion). Risk is low for uncoated polyester mesh worn next to skin for short durations during athletics.
Heavy metals
Printing inks can contain trace heavy metals (lead, cadmium) depending on pigment formulation. Brooks does not certify this singlet to heavy-metal limits under OEKO-TEX or similar standards. Risk is low because printed area is small and skin contact is brief during athletic use, and no ingestion pathway exists for apparel.

Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
No evidence that this singlet uses formaldehyde-releasing resins (typically used for wrinkle resistance or stiffness). Mesh singlets are rarely finished with such treatments because moisture-wicking requires an open, untreated structure. Not a documented concern for this product class.
Source, ATSDR ↗Antimony in polyester
Antimony trioxide is a catalyst used in polyester production and can remain as residue in the final fiber. At the levels found in textiles, no health risk is established during normal wear. Antimony is not listed as a concern in any Brooks singlet safety data or regulatory filings.
Fragrance allergens
This is an unscented athletic singlet with no intentional fragrance addition. No documented allergen risk from the product itself, though residual dye or finish odors may be present before first wash.
The full breakdown
What it's made of and why it matters
This singlet is polyester mesh, a synthetic fiber chosen for moisture-wicking and breathability in athletic wear. Polyester itself is a stable plastic polymer that does not leach chemicals during normal wear. The printed graphic adds a potential exposure point for dyes and pigment binders, but printed apparel hazards are typically acute only if fabric is heavily treated with finishes (waterproofing, softening resins) or involves reactive dyes with poor fixation.
The brand's record and disclosure
Brooks does not publish detailed chemical safety disclosures for individual apparel products, which is common for athletic brands but limits transparency. The company has no known recalls or regulatory violations related to hazardous substances in singlets or mesh clothing. Brooks belongs to the Apparel and Footwear Association and adheres to basic compliance with US and EU textile regulations, but does not voluntarily certify to higher standards (OEKO-TEX, bluesign) for this product line.
How it compares in its category
Men's running singlets are among the lowest-risk apparel items because they are minimal-finish products with small surface area. Unprinted mesh would have lower concern from printing chemicals, but printed singlets are standard in this category. Competitors like Nike, Adidas, and Salomon operate under similar disclosure and compliance practices; Brooks does not stand out as notably better or worse for this product type.
If you buy it
Wash before first wear to reduce loose dyes and finishes. Use cool water and mild detergent, and avoid prolonged heat exposure (do not machine dry on high; air dry or low heat preferred). No special care beyond standard athletic wear is needed. Replace if seams degrade or elastic loses tension, which typically occurs after 50-100 washes for athletic mesh.
