Black Diamond Wall Haul Bag
Unclear coating type; brand does not disclose PFAS status.
Wall haul bags typically use water-repellent coating-treated nylon. Black Diamond does not publicly disclose PFAS chemistry or claim PFAS-free. Contact brand directly for coating specifics.

The full breakdown
What it's made of and why it matters
Black Diamond Wall Haul Bag is constructed from nylon fabric with an applied waterproof coating. The coating type (polyurethane, silicone, wax, or Teflon-family coating-based) is not specified in public materials, which is the core safety gap. Nylon itself is stable and non-toxic, but the coating's durability and leaching behavior under moisture and UV exposure depend entirely on its chemical composition. The nylon may also contain dyes and processing agents applied during manufacture.
The brand's record and disclosure
Black Diamond Equipment is an outdoor climbing and skiing brand owned by Clarus Corporation with a strong reputation for product durability and quality control. However, the company has not published publicly available statements regarding PFAS use, Teflon-family coating coatings, or hazardous chemical phase-outs for any of its textile products. No third-party certifications (Bluesign, OEKO-TEX, Fair Trade) are advertised for this haul bag, and no product-specific safety disclosures appear in readily accessible materials.
How it compares in its category
Wall haul bags are specialty climbing gear designed for durability over chemical transparency. Most competitors (including budget brands) similarly withhold waterproof coating details. Unlike everyday apparel, haul bags see limited skin contact and brief moisture exposure, reducing leaching risk compared to rainwear or base layers. However, the lack of standard certifications puts this product at the middle-to-lower end of transparency for premium outdoor brands, where some competitors (e.g., Patagonia) disclose more.
If you buy it
Minimize direct skin contact with the wet outer coating, especially on damp days, and allow the bag to dry fully before storage to prevent mildew and coating degradation. Avoid prolonged sun exposure when not in use, as UV can degrade coatings and increase leaching potential. Wash by hand with cold water and mild soap only; hot water or machine washing may accelerate coating breakdown. Replace the bag if the waterproof coating begins to peel, crack, or become tacky, as this signals chemical breakdown and loss of water resistance.
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.”
Waterproof coating composition (unidentified polymer)
Black Diamond does not disclose whether the coating is Teflon-family coating (PFAS-bearing), polyurethane, silicone, or wax-based. Unknown coating chemistry creates uncertainty about leaching behavior when wet and potential off-gassing during storage or use.
Azo dyes in nylon fabric
No recalls or public warnings exist for this specific haul bag. Nylon textiles may contain azo dyes that can break down into aromatic amines under extreme heat or in acidic/alkaline conditions; however, haul bag use (dry storage, occasional contact with sweat) presents minimal risk compared to apparel worn directly on skin.
Coating degradation and microparticle shedding
Waterproof coatings on nylon degrade over years of UV exposure and flexing. As the coating cracks or peels, microscopic particles may be shed; the composition of these particles (whether polymeric, filler, or adhesive) depends on the unknown coating type. Inhalation risk is low during normal outdoor use but may increase during indoor storage if the bag sheds in an enclosed space.
Dye or processing agent residue on new product
Nylon manufacturing involves dyes and chemical finishing agents (e.g., antistat agents, softeners) that may remain on the fabric after production. Direct skin contact with a new, unwashed haul bag could cause mild irritation in sensitive individuals; this risk is mitigated by the typical use pattern (external carry gear).
Solvent or adhesive off-gassing from coating and seams
Waterproof coatings and seam sealing adhesives may emit volatile organic compounds (VOCs) if the coating is polyurethane-based or solvent-applied. No test data or complaints are on record for this bag, and outdoor use (with air circulation) minimizes inhalation risk compared to indoor storage or enclosed climbing vehicles.
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.
