What Ariat Men's Rebar M7 DuraStretch Made is made of, ingredients and materials

Ariat Rebar M7 uses a cotton-polyester blend treated with DuraStretch, a synthetic elastane or spandex-based stretch additive, plus an unspecified water-repellent coating (water-repellent coating) finish. water-repellent coating coatings on work apparel commonly use fluorinated compounds (PFAS-based) or newer alternatives; Ariat has not publicly disclosed which. The polyester component may contain antimony catalyst residue (standard in synthesis) and azo dyes for color, both potential concerns if not tightly controlled.

Formaldehyde / VOCs

Cotton-polyester work pants commonly use formaldehyde-based resins for wrinkle resistance and shape retention; not listed on product specs. Risk is low if laundered before wear and worn on skin. Ariat has not publicly disclosed formaldehyde-free finishes for this line.

Azo dyes and color stability

Polyester blends in dark or saturated colors typical of work pants often use azo dyes, which can degrade into aromatic amines under sweat and friction. Pre-washing and avoiding excessive heat drying reduce this risk. No known brand recalls for azo dye issues in Ariat products.

water-repellent coating (water-repellent coating) coating durability and leaching

Water-repellent coating finishes on work pants degrade with washing and wear, releasing microparticles and residual chemicals. Ariat's undisclosed water-repellent coating type (fluorinated vs. fluorine-free) makes risk assessment difficult. Avoid permanent press cycles and use warm rather than hot water to extend water-repellent coating life and minimize off-gassing.

Microplastics

Polyester-blend pants shed microfibers during washing, particularly in the first 10 washes. The DuraStretch treatment may increase shedding due to surface coating friction. Use a microfiber-catching laundry bag or filter if environmental impact is a concern.

What’s reassuring

✅

Antimony in polyester fiber

Polyester is synthesized with antimony oxide catalyst; residual antimony content is typically below 0.05 percent and is not reported as a hazard in polyester work apparel. Ariat does not publish antimony testing data for this product.

The full breakdown

The brand's record and disclosure

Ariat (owned by Tapestry Inc.) does not maintain publicly visible PFAS or chemical hazard disclosures for individual product lines. The brand holds no prominent third-party textile certifications (OEKO-TEX, bluesign) for this work pant line. No recalls or substantiated safety incidents are on record for this specific model. Ariat's corporate sustainability reporting does not detail water-repellent coating chemical choices or restricted substance policies.

How it compares in its category

Work pants in this price tier typically use polyester blends with water-repellent coating finishes; Ariat's lack of transparency is common among mainstream outdoor/workwear brands. Premium alternatives (Carhartt FR, Dickies) and certified options (OEKO-TEX labeled work wear) are available but often at higher cost. The DuraStretch treatment is a competitive feature but adds chemical complexity without public ingredient disclosure.

If you buy it

Wash in cold water and avoid high heat drying; water-repellent coating finishes degrade faster with hot water and can release coating residues. Expect DuraStretch elasticity to decline after 50-100 wash cycles; pilling or color fading from azo dyes is normal. Do not tumble dry on high heat, as this can degrade synthetic treatments and polyester fibers. If rash, itching, or irritation occurs during first few wears, pre-wash thoroughly before extended wear.
