The full breakdown
What it's made of and why it matters
The Distance 15 is constructed from nylon and polyester fabrics with a water-repellent coating (water-repellent coating) coating. water-repellent coating treatments historically rely on PFAS "forever chemicals" (PFAS) to achieve water shedding, though newer non-fluorine options exist. Black Diamond has not publicly specified which chemistry this backpack uses, leaving the PFAS content uncertain. Polyester and nylon themselves are stable synthetic polymers with no established leaching concerns in normal backpack use.
The brand's record and disclosure
Black Diamond, owned by Clarus Corporation, does not maintain public transparency on PFAS use or elimination timelines across its product lines. The company has not published chemical disclosure statements, third-party certifications (such as Bluesign or GOTS), or water-repellent coating supplier commitments. No recalls or safety violations specific to this backpack model are on record. The brand's silence on this issue is typical of climbing and outdoor gear manufacturers, most of whom have not yet made formal PFAS commitments.
How it compares in its category
Outdoor backpacks commonly use fluorine-based water-repellent coating coatings for durability, placing this product in the mainstream of the category rather than an outlier. Some competitors (Patagonia, The North Face) have begun disclosing water-repellent coating strategies or moving toward PFAS-free alternatives, making Black Diamond's silence relatively more opaque. For a lightweight day pack, water resistance is a minor performance feature; non-water-repellent coating or PFAS-free alternatives exist but may require more frequent reproofing. The backpack itself is well-reviewed for durability and function, unrelated to chemical hazards.
If you buy it
Minimize skin contact with the exterior fabric, particularly in wet conditions when water-repellent coating coatings are most active. Do not machine wash; hand wash in cold water and air dry to avoid degrading any coating and limit release. Do not tumble dry or expose to high heat, which can compromise both fabric and coating integrity. Replace the backpack if the water-repellent coating visibly delaminates or if the outer fabric shows cracks, as degraded coatings may shed particulates.
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.”
PFAS in water-repellent coating
Black Diamond has not disclosed whether this backpack uses fluorine-based or alternative water-repellent coating chemistry. Conventional water-repellent coating formulations in outdoor gear typically contain legacy or short-chain PFAS, but absence of disclosure means exposure cannot be ruled out or confirmed.
Azo dyes in colored nylon/polyester
No specific testing or recalls for azo dyes in Black Diamond backpacks have been reported. Polyester and nylon textiles may contain azo dyes as standard practice, but these are generally not considered a dermal or ingestion hazard during normal wear of a backpack.
Antimony in polyester
Polyester production may involve antimony as a catalyst; residual levels in finished textiles are typically low and pose minimal hazard during normal backpack use. No specific data for this product or brand exists.
Formaldehyde resins in fabric finishing
Nylon and polyester backpack materials may be treated with formaldehyde-based resins for wrinkle resistance or fire retardancy, but outdoor gear does not routinely require such treatments. No reports of formaldehyde hazards from this product or brand are documented.
Coating degradation and particulate shedding
water-repellent coating coatings, whether PFAS-based or alternative, can degrade with age, washing, and UV exposure, potentially releasing coating fragments. This is a mechanical rather than toxicological hazard but is relevant if the backpack is used in high-wear conditions over years.
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.
