Reebok Men's Crest Shorts
Likely lower concern, but Reebok discloses no PFAS details.
Standard athletic shorts with no visible water-resistant or stain treatment claims. Reebok makes no public PFAS commitments; polyester/nylon base is inherently PFAS-free, but finishes unknown.

The full breakdown
What it's made of and why it matters
Reebok Crest Shorts are a polyester/nylon blend, both synthetic thermoplastics commonly used in athletic apparel. Polyester is chemically stable under normal wear and washing; nylon adds durability and stretch. Neither material is known to leach toxic substances during typical use (wearing, sweating, washing at normal temperatures). The concern arises only if the blend includes certain finishes, dyes, antimony catalysts in polyester production, or flame retardants, which are not disclosed here.
The brand's record and disclosure
Reebok does not publicly disclose fiber sourcing, dye safety, or finish details for this product line. The brand has faced scrutiny for chemical management (legacy fast-fashion practices) but no specific recalls or documented hazards tied to Crest Shorts have been recorded. Reebok is owned by Authentic Brands Group (as of 2022) and does not hold major third-party certifications (e.g., OEKO-TEX, Bluesign) that would independently verify finishes.
How it compares in its category
Standard athletic shorts from mass-market brands (Nike, Adidas, Puma) present similar undisclosed-finish profiles. Certified alternatives (OEKO-TEX or Bluesign-labeled polyester shorts) offer independent testing for azo dyes and heavy metals but cost more. Reebok Crest Shorts occupy the middle market: no red flags, but also no proactive transparency, placing them on par with most retail competitors.
If you buy it
Wash in cool to warm water (below 60°C/140°F) before first wear to reduce loose dye transfer and any residual finishes. Avoid prolonged heat (tumble-dry on low or air-dry) to prevent nylon degradation and pilling. Replace if elastic degrades or seams fray, as this can create microfiber shedding during washing. No special care is required beyond standard athletic-wear laundering.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Azo dyes and heavy metals in colorants
Polyester and nylon shorts often use reactive or azo dyes; Reebok does not certify dye safety. Risk is minimal during wear but loose dyes may leach slightly in first few washes. No recalls or test failures specific to Crest Shorts have been reported.
Antimony catalyst residue in polyester
Polyester is typically produced using antimony trioxide as a catalyst. Residual antimony in finished fabric is rare and not bioavailable during normal wear; no established risk from wearing polyester apparel has been documented in published literature.
Flame retardants or finishes
No disclosure of flame-retardant treatments on this product. Athletic shorts are not required to meet flame standards (unlike children's sleepwear), so chemical finishes are unlikely but unconfirmed.
Microfiber shedding during laundering
All synthetic-blend shorts shed microfibers when washed; this is not a personal safety hazard but an environmental concern. Washing in cold water and using a microfiber filter bag reduces shedding by up to 80%.
Formaldehyde resins in wrinkle resistance or sizing
Budget athletic shorts may use low-formaldehyde finishes for shape retention or crease-setting. Formaldehyde off-gassing is minimal in polyester/nylon blends and dissipates within days of opening. No specific testing or complaints for Reebok Crest Shorts are on record.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 68% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
