Columbia Triple Canyon 36L Backpack
Backpack likely treated for water repellency; Columbia discloses nothing about PFAS.
Columbia Triple Canyon uses standard water-repellent coating-treated nylon, common in outdoor backpacks. No public PFAS statement from Columbia; water-repellent treatments often contain fluorochemicals but specific chemistry unknown.

The full breakdown
What it's made of and why it matters
The Columbia Triple Canyon is constructed from nylon fabric, a durable synthetic polymer common in outdoor gear. The fabric carries a water-repellent coating (water-repellent coating) finish, which manufacturers typically apply to repel rain and moisture without creating a waterproof seal. water-repellent coating treatments historically relied on fluorinated compounds (PFAS), though the chemistry and specific formulations Columbia uses are not publicly disclosed.
The brand's record and disclosure
Columbia Sportswear has not published transparent information about PFAS use in their backpacks or water-resistant product lines. The brand has not committed to phasing out fluorinated water-repellent coating treatments or obtaining certifications like OEKO-TEX or Bluesign that restrict such chemicals. Without public disclosure, it is reasonable to assume conventional fluorinated water-repellent coating chemistry may be present in this product.
How it compares in its category
Most nylon backpacks in Columbia's price and performance tier use some form of water repellency treatment; few brands in the mainstream outdoor market disclose their specific chemistry. Specialty brands like Patagonia and The North Face have begun phasing toward fluorine-free or lower-PFAS alternatives, though not uniformly across all products. Columbia's lack of disclosure places this backpack in the middle of a broad market where PFAS-treated gear is still standard.
If you buy it
Wash the backpack every 1-2 seasons with regular detergent and air dry to maintain water-repellent coating performance without triggering off-gassing. Do not machine dry, iron, or apply heat sources, as excessive heat can degrade nylon and potentially mobilize surface coatings. Replace the pack if seams fray, fabric tears, or water no longer beads on the surface; degraded nylon and water-repellent coating are not repairable.
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 water-repellent finish
Columbia has disclosed no PFAS-free commitment or testing for this product. Fluorinated water-repellent coating treatments remain industry standard for nylon performance gear at this price point.
Formaldehyde resins in fabric dyes or sizing
No published recalls or test results document formaldehyde in Columbia backpack textiles. Nylon fabric itself does not require formaldehyde resin binders, so risk is minimal unless specialty dyes or stiffening agents are used.
Azo dyes (carcinogenic colorants)
Columbia backpacks are not documented to use restricted azo dyes. Without OEKO-TEX or Bluesign certification, compliance with azo dye restrictions cannot be independently verified.
Antimony in polyester components
This backpack is primarily nylon; if polyester webbing or thread is present, antimony is theoretically possible but not reported in Columbia products.
Degradation of nylon fabric releasing microfibers
Washing releases small nylon fibers into wastewater. While not a direct health hazard to the user, prolonged use and laundering contribute to microplastic pollution; this is a property of nylon gear generally, not specific to Columbia.
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.
