HOKA · Synthetic Athletic Wear
Hoka Men's Race Day Singlet
Lower concern, no waterproofing or water-repellent coating treatment typical for race singlets.
This race singlet is typically uncoated polyester mesh without water-repellent finishes. HOKA does not disclose PFAS use; standard athletic singlets pose lower risk than treated outerwear.

What Hoka Men's Race Day Singlet is made of, ingredients and materials
The Hoka Race Day Singlet is constructed from polyester mesh and polyester fabric designed for moisture-wicking and breathability in endurance running. Polyester itself is a synthetic polymer with low toxicity during normal wear, but the finishing treatments applied during manufacturing are the primary safety consideration. Since this is an uninsulated, non-waterproofed race garment, it avoids the more hazardous treatments (flame retardants, water repellents) common in technical outerwear.
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.
Heavy metals
Polyester textiles are commonly dyed with azo dyes and may contain heavy metal mordants (lead, chromium); no specific test results for this singlet are publicly available, but risk exists across most polyester apparel.
Source, FDA ↗Formaldehyde / VOCs
Polyester fabrics sometimes receive formaldehyde-based wrinkle-resistant or antimicrobial finishes during manufacturing. Race singlets typically use minimal finishing, lowering exposure, but residual formaldehyde cannot be ruled out without mill disclosures.
Source, ATSDR ↗Microplastic shedding on wear and wash
Polyester mesh and woven fabrics shed microfibers during normal use and especially in washing. This is a documented environmental and potential human inhalation concern, though direct health evidence in garment wearers remains limited; washing separately and in cold water reduces shedding.
Antimony in polyester polymer
Antimony trioxide is a common catalyst in polyester production. Finished garments retain trace amounts; migration into skin is considered negligible under normal wear, but degraded or heated fabric theoretically increases release risk.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Fragrance allergens in dyes or treatments
Hoka has not added fragrance to this singlet's known formulation. Allergen risk from dyes themselves is product-specific and not documented for this model.

The brand's record and disclosure
Hoka is owned by Deckers Brands and does not publicly disclose detailed chemical treatment protocols for individual garments, though the parent company has general sustainability commitments. No recalls or safety warnings specific to this singlet are on record. The brand's silence on PFAS and dye chemistry is typical of athletic wear companies, though it reflects lack of transparency rather than confirmation of absence.
How it compares in its category
Race singlets as a category carry lower chemical risk than insulated jackets or treated base layers because they require minimal finishing. This product is standard for its class, uncoated polyester mesh with simple construction. Comparable competitors from Nike, Brooks, and Salomon follow similar material profiles without notable safety differentiation in available disclosures.
If you buy it
Wash in cool water with mild detergent to reduce microfiber shedding and preserve fabric integrity. Avoid high heat in dryers, as polyester can degrade and potentially off-gas volatile compounds; air-dry when possible. Replace when seams fray, elastic loses recovery, or fabric pilling becomes visible, as degraded coatings increase microplastic risk. Store dry in a ventilated space to prevent mildew.
