Black Diamond Wall Hauler 70 Haul Bag
No PFAS disclosure on haul bag; waterproof coating risk unclear.
Black Diamond does not disclose PFAS use in this durable nylon haul bag. Waterproof treatments on outdoor gear commonly contain PFAS, but specific coating unconfirmed here.

The full breakdown
What it's made of and why it matters
The Wall Hauler 70 uses ballistic nylon, a tightly woven polyamide fabric chosen for abrasion resistance and tear strength in climbing and hauling applications. The waterproof treatment applied to this nylon is the primary chemical concern; Black Diamond does not publicly specify whether this coating uses PFAS compounds (like PFC) or alternative hydrophobic treatments. Ballistic nylon itself is chemically inert in normal use, but the durability and composition of the water-repellent finish directly affects what may leach or off-gas over the product's life.
The brand's record and disclosure
Black Diamond, a subsidiary of Clarus Corp, has not published transparent chemical disclosures or PFAS statements for this haul bag or most of its gear line. The company does not appear on public PFAS-free commitment lists or environmental health transparency databases. The brand has faced no major recalls or safety controversies related to its bags, but the absence of proactive disclosure on waterproof coatings is notable in an industry where competitors increasingly specify non-fluorinated alternatives.
How it compares in its category
Haul bags are specialty climbing gear; most competitors (Patagonia, Edelrid, some offerings from Mammut) similarly use ballistic nylon with proprietary waterproof treatments, and PFAS disclosure is rare across the category. Black Diamond's lack of transparency is typical rather than exceptional, but some brands now offer or highlight non-fluorinated coating options. As a technical hauling product, it is not a food-contact or water-storage item, so chemical migration pathways are lower than in cookware or food containers.
If you buy it
Store in a cool, dry place away from direct prolonged sunlight to slow any coating degradation. Inspect seams and coating annually for tears or flaking; a compromised coating reduces waterproofing but does not create acute hazard from material fragments in normal use. Clean with mild soap and water only; avoid solvents or harsh detergents that may accelerate coating breakdown. If you're sensitive to chemical off-gassing or have concerns about PFAS exposure, contact Black Diamond directly to request the technical datasheet for the waterproof coating before purchase.
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 (PFAS risk)
Black Diamond does not disclose whether the water-repellent coating (water-repellent coating) finish on this ballistic nylon uses fluorinated PFAS compounds or non-fluorinated alternatives. This is the primary unresolved chemical concern for the product.
Coating degradation and leachables
As the coating ages through sun, friction, or washing, microparticles or soluble residues may shed; the chemical identity of these residues is unknown without disclosure. Risk is low for a dry-storage item but increases with wet conditions or frequent abrasion.
Polyamide (nylon) fiber shedding
Ballistic nylon is chemically stable and does not typically release harmful substances under normal use. Microfiber shedding during washing is a potential environmental concern but not an acute health hazard to the user.
Off-gassing from synthetic materials
New ballistic nylon and its coatings may emit low levels of volatile organic compounds (VOCs) initially; this is typical for technical textiles and typically negligible after airing out the product. No specific off-gassing incidents reported for Black Diamond haul bags.
Heavy metal content in dyes or treatments
Ballistic nylon is typically dyed with modern azo dyes and does not carry known heavy metal contamination risk. No recalls or test failures reported for Black Diamond nylon products in this hazard class.
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.
