Reebok Women's Sleeveless Training Tank Top
Lower concern, basic athletic tank with no water-repellent coating or stain treatment.
Sleeveless training tank is plain polyester blend with no water-repellent or stain-resistant coating mentioned. No PFAS disclosure is expected for uncoated sportswear.

What Reebok Women's Sleeveless Tank Top is made of, ingredients and materials
This tank is polyester blend (polyester primary fiber), likely 88% polyester/12% spandex or similar ratio based on typical Reebok athletic construction. Polyester itself is chemically stable during normal wear. The hazard surface is the dyes and finishing chemicals applied during manufacturing. No water-repellent or stain-resistant coating is claimed, which removes one major source of textile chemical burden. The spandex component (elastane) can offgas slightly but is minimal at this blend ratio.
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 tanks require synthetic dyes. Reebok does not publicly certify azo dye restrictions or cadmium/lead limits in colorants. Risk is low in actual use (dyes are fixed to fiber) but small dye bleed in early washes and onto skin is possible. Darker colors carry slightly higher risk profile.
Source, FDA ↗Formaldehyde / VOCs
Low-level formaldehyde is used in many polyester blend finishes for wrinkle resistance and color lock. Reebok does not disclose formaldehyde limits. Off-gassing risk is minimal post-manufacture and wash, but new garment odor may indicate residual finish.
Source, ATSDR ↗Spandex (elastane) degradation and microfiber release
Spandex component will degrade over time with heat, UV, and chlorine exposure, potentially releasing microfibers. This is a wear-and-tear issue rather than a manufacturing hazard. Replacement every 12-24 months of regular use is typical for athletic tanks.
Fragrance or finishing chemical allergens
Reebok does not disclose fragrance or finishing agents in manufacturing. Individuals with sensitive skin or fragrance sensitivity may react to residual finish chemicals. Pre-wash strongly recommended.
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 fiber
Polyester can contain antimony as a catalyst residue from synthesis. Modern fiber makers (used in Reebok supply) typically maintain low antimony content and Reebok products have not been flagged in testing. No recall or contamination on record for this product line.
How is this PFAS grade calculated?
The brand's record and disclosure
Reebok does not publicly disclose restricted substance testing results or dye/finish chemical inventories for most apparel lines, including basic tanks. The brand has faced no major recalls or legal action tied to formaldehyde, heavy metals in dyes, or azo dyes in recent years. Reebok is owned by Authentic Brands Group (as of 2022) following Adidas divestiture; safety standards inherited from Adidas supply chains remain in place but transparency remains limited for mid-tier products.
How it compares in its category
Uncoated polyester athletic tanks are among the lower-risk garment types because they lack chemical finishes (water-repellent coating, antimicrobial, or flame retardant coatings). Reebok's standard manufacturing is comparable to Nike, Adidas, and Under Armour basics in chemical hazard profile. This tank offers no certification (Oeko-Tex, GOTS, bluesign) that would reduce dye/finish risk; certified competitors exist but at higher price. For unadorned athletic basics, Reebok sits in the middle-market safety tier.
If you buy it
Wash in cool water before first wear to reduce loose dyes and residual finishes. Use gentle or regular cycle (no heat needed for polyester/spandex blend). Avoid chlorine bleach and very hot water, which can degrade spandex and potentially mobilize trace heavy metals in darker dyes. Replace when elastication fails (typically 60-100 wears for athletic tanks) or visible pilling/degradation occurs. Machine dry on low or air dry; high heat weakens spandex.
