Ariat · Stain-Resistant Workwear
Ariat Men's Rebar M5 DuraStretch Made Tough Straight Pant
Work pants with water-repellent coating treatment; Ariat silent on PFAS use.
Ariat's Rebar M5 uses DuraStretch fabric technology and likely water-resistant treatment, but the brand discloses nothing about PFAS content. water-repellent coating finishes commonly contain legacy PFAS; no third-party verification available.

The full breakdown
What it's made of and why it matters
These pants are a cotton-polyester blend (typical ratio around 60/40 or 70/30) with a DuraStretch treatment for flex and a water-repellent coating (water-repellent coating) finish. The water-repellent coating is the primary chemical concern, as most industrial water-repellent coating treatments historically relied on PFAS compounds, though Ariat has not publicly disclosed whether this specific product uses legacy PFAS, newer fluorine-free alternatives, or hydrocarbon-based repellents. The polyester component introduces potential for azo dyes and other synthetic colorants; the cotton buffer reduces but does not eliminate skin-contact risks. The DuraStretch treatment itself is typically a resin or elastane blend, not inherently hazardous in normal use.
The brand's record and disclosure
Ariat is a major workwear and equestrian brand owned by Vedanta Limited. The company has not made public commitments to PFAS phase-out or transparent chemical disclosure policies in the manner of leading outdoor brands (Patagonia, The North Face). No major recalls related to chemical hazards in Ariat apparel are established in public records. The brand's silence on water-repellent coating treatment chemistry is notable given industry pressure to disclose or eliminate PFAS; this absence of clarity suggests either legacy formulations or a decision not to differentiate on chemistry.
How it compares in its category
Work pants with water-repellent coating finishes are category-standard; Ariat's positioning is mid-market durability-focused, not premium or eco-conscious. Competitors like Carhartt and Dickies similarly use water-repellent coating treatments without transparent PFAS disclosure, making this product typical rather than exceptional. Premium workwear brands (e.g., RedHead, some Duluth Trading lines) increasingly market PFAS-free or fluorine-free water-repellent coating; budget and mainstream workwear, including this line, have not universally adopted that standard.
If you buy it
Wash in cool water with mild detergent to preserve the water-repellent coating finish and minimize any leaching of treatment chemicals during early wear. Avoid hot water and high heat drying, which can degrade synthetic coatings and elastane faster. Expect to re-wash new pants separately or with similar colors to remove excess dyes (standard for synthetic-blend workwear). Inspect seams and crotch stitching after 10-15 washes; this product's durability claims are only credible with proper care.
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 synthetic colorants
Polyester-blend workwear typically uses azo dyes; low skin-contact risk in finished form, but not established as absent. No specific testing of this Ariat line is on record.
Formaldehyde in resin finishes
DuraStretch and standard cotton-polyester blends may include low-level formaldehyde-releasing resins for wrinkle resistance. No documented concerns specific to this product, and any residual exposure after first wash is minimal.
Coating degradation and chemical leaching from water-repellent coating
water-repellent coating treatments degrade with repeated washing. If this product uses legacy PFAS formulations (unconfirmed), repeated laundering will shed fluorinated compounds into wash water. Even fluorine-free water-repellent coating finishes release treatment byproducts over time.
Antimony in polyester
Polyester fibers may contain antimony catalysts from manufacturing; levels in finished apparel are generally far below health concern thresholds. No specific testing of this Ariat product exists.
Elastane (spandex) and synthetic blend durability
DuraStretch technology likely incorporates elastane or polyurethane; these degrade with heat and UV exposure. Premature loss of stretch could indicate coating breakdown, signaling time for replacement.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
