Columbia Blackcomb Ridge Backpack
Backpack likely water-repellent coating treated; PFAS risk unknown due to no disclosure.
Columbia does not publicly disclose PFAS content or treatment details for this backpack. Most outdoor backpacks use water-repellent coating coatings that historically contained PFAS, though newer alternatives exist. No lab data available.

The full breakdown
What it's made of and why it matters
The Blackcomb Ridge uses nylon and polyester as primary materials with a water-repellent coating (water-repellent coating) finish applied to the exterior. Nylon and polyester themselves are stable synthetic fibers with low leaching risk under normal use. The water-repellent coating is the concern: traditional formulations rely on fluorinated compounds (PFAS) to create water beading, but some manufacturers have shifted to non-fluorinated alternatives. Columbia has not publicly disclosed which water-repellent coating chemistry this backpack uses, leaving the PFAS exposure profile unknown.
The brand's record and disclosure
Columbia Sportswear has not issued public statements about PFAS elimination from its apparel product line, and does not list this backpack or similar items in transparency reports. The brand does not appear on lists of companies committed to PFAS phase-out (such as those from Textile Exchange or similar initiatives). No recalls or safety controversies specific to this backpack have been documented in public records.
How it compares in its category
Most outdoor nylon backpacks in this price and performance tier use water-repellent coating coatings; the uncertainty is industry-wide rather than unique to Columbia. Brands like Patagonia and The North Face have made more explicit commitments to fluorine-free water-repellent coating, though verification remains difficult. A backpack's durability and water resistance depend heavily on water-repellent coating, so choosing an alternative typically means accepting either reduced performance or paying a premium for disclosed non-fluorinated versions.
If you buy it
Wash the backpack only when visibly soiled; frequent laundering can degrade the water-repellent coating and potentially release coating particles. Use cool water and mild detergent; avoid dry cleaning and high heat. The water-repellent coating will eventually wear off after 1-2 years of heavy use, at which point water resistance declines but the backpack remains functional. Store in a dry location to prevent mold growth in the synthetic fabric, which does not support bacterial colonization but can trap moisture if packed wet.
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.”
water-repellent coating degradation and particle shedding
As the water-repellent finish wears from abrasion and washing, micro-fragments may shed into the environment; no established risk to the user, but landfill impact is unknown for fluorinated coatings.
Azo dyes in polyester/nylon fabric
Columbia products are not documented to use restricted azo dyes that break down into carcinogenic amines, and polyester/nylon dyes are generally stable; no recalls or reports for this product line.
Formaldehyde resins in textile finishing
Formaldehyde-based wrinkle-resist and color-fixative resins are not typical in outdoor backpack construction; no evidence this product uses such treatments.
Antimony in polyester
Polyester fibers may contain trace antimony as a catalyst residue from manufacturing, but migration to skin or food is not established as a practical hazard under normal backpack use.
Mold and bacterial growth if stored damp
Nylon and polyester do not inherently support microbial growth, but trapped moisture in the packed backpack can promote mold on the interior lining; preventable through proper storage in a dry state.
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.
