Reebok Women's Lux Metallic 2-In-1 Running Shorts
water-repellent coating athletic shorts; PFAS risk unclear, brand silent on composition.
Metallic running shorts likely use water-repellent coating treatment, a common PFAS source in athletic wear. Reebok offers no PFAS-free claim or coating details.

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
PFAS
Polyester athletic shorts commonly use fluorinated water-repellent coating finishes, but Reebok has not disclosed whether this product contains traditional PFAS-based water-repellent coating or newer non-fluorinated alternatives. Risk is composition-dependent and currently unverified.
Source: ATSDR ↗What’s reassuring
Azo dyes in polyester fabric
No specific recalls or reports link Reebok's polyester apparel to restricted azo dyes. Standard polyester dyeing is regulated in major markets, but individual product dye screening is not typically disclosed.
Formaldehyde / VOCs
Formaldehyde-based finishes are less common in modern athletic wear than in dress shirts, and no documented cases of formaldehyde release from Reebok performance shorts have surfaced. Brief off-gassing after purchase is possible but typically minimal.
Source: ATSDR ↗Microfiber shedding from polyester blend
All polyester garments shed microfibers during washing; this is an environmental and potential ingestion concern across the category, not specific to Reebok, and no brand has eliminated it.
Antimony in polyester fiber
Antimony trioxide is used as a catalyst in polyester production but typically remains bound in the polymer. No public records indicate excessive antimony leaching from Reebok polyester apparel or shorts in particular.
The full breakdown
What it's made of and why it matters
These shorts are polyester-blend fabric treated with a water-repellent coating (water-repellent coating) finish. water-repellent coating coatings on athletic wear historically used PFAS-based chemistry to achieve water and stain resistance; Reebok has not publicly disclosed whether this product uses traditional fluorinated water-repellent coating or newer alternatives. Polyester itself is chemically stable in normal wear, but the finish treatment is the key unknown here.
The brand's record and disclosure
Reebok (owned by Authentic Brands Group as of 2022) has not released detailed PFAS phase-out commitments or material transparency reports comparable to leading athletic brands like Nike or Adidas. The company's silence on water-repellent coating composition across its performance lines is notable. No major recalls or safety violations specific to Reebok apparel's chemical content have reached public record, but absence of disclosure is itself a risk signal for consumers seeking certainty.
How it compares in its category
Most mainstream athletic shorts in this price range use polyester with water-repellent coating treatment, placing Reebok in the typical category rather than at either extreme. Some competitors (Patagonia, Arc'teryx) now explicitly offer PFAS-free water repellency or disclose fluorocarbon-free options. Others, including many Reebok lines, remain silent. This product offers no distinguishing transparency advantage.
If you buy it
Wash in cold water and avoid prolonged heat exposure, as water-repellent coating finishes can degrade unevenly with hot water and dryer cycles, potentially creating wear patterns. The shorts are safe to wear as-is; the main concern is unknown water-repellent coating chemistry rather than acute hazard. If PFAS exposure is a personal priority, contact Reebok directly to request water-repellent coating composition before purchase, or choose competitors with documented non-fluorinated finishes. Replace if the water-repellent finish visibly fails or degrades unevenly.
