Columbia Women's Cassiar Pro ODX Waterproof Jacket
Waterproof jacket with undisclosed water-repellent coating treatment; elevated PFAS risk.
Columbia's Cassiar Pro uses ODX waterproof technology but does not disclose PFAS status. Waterproof jackets typically use PFAS-based water-repellent coating coatings unless stated otherwise.

The full breakdown
What it's made of and why it matters
The Cassiar Pro uses nylon and polyester blended fabric with an applied ODX waterproof/water-repellent coating (water-repellent coating) coating. Nylon and polyester themselves are stable synthetic fibers with no inherent lead, cadmium, or azo-dye hazards in typical production. However, the ODX coating is where risk concentrates: Columbia does not publicly disclose whether this coating uses PFAS-based chemistry (such as Teflon-type coating or fluorocarbon water-repellent coating) or newer PFAS-free alternatives. The coating degrades over time and with washing, which could theoretically increase particle shedding, though documented health data on inhaling synthetic-fiber particles from worn clothing is limited.
The brand's record and disclosure
Columbia Sportswear has not made public commitments to phase out PFAS from apparel or adopted third-party certifications like OEKO-TEX or Bluesign that verify absence of restricted chemicals. The company does not disclose water-repellent coating chemistry on product labels or websites for most styles. This silence is notable because many competitors (Patagonia, Arc'teryx, The North Face) now explicitly market PFAS-free or low-PFAS options. Columbia's lack of transparency around ODX suggests either PFAS-based formulation or reluctance to clarify, both of which increase consumer uncertainty.
How it compares in its category
Waterproof jackets broadly split into PFAS-based (cheaper, longer-lasting water repellency) and PFAS-free (wax-, silicone-, or paraffin-based water-repellent coating; less durable, require more frequent reapplication). The Cassiar Pro is positioned as a mid-range utility jacket; its price point and lack of PFAS-free marketing suggest PFAS-based water-repellent coating is likely, though not confirmed. Competitors offering documented PFAS-free or PFAS-reduced options (such as Patagonia Calcite or Arc'teryx Atom) exist at similar or slightly higher cost, making this product less distinctive on safety grounds.
If you buy it
Wash infrequently (every 10-20 wears) to prolong water-repellent coating life and minimize coating breakdown. Use cool water and mild detergent; avoid fabric softeners and heat drying, which degrade the coating faster. Do not dry clean, as perchloroethylene solvents can interact with fluorinated coatings. If water no longer beads on the surface after 2-3 years, the water-repellent coating is exhausted; reapplication products exist but also typically contain PFAS. At that point, consider replacement or repair via a professional service.
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 (fluorinated water repellent)
ODX coating composition is undisclosed; standard mid-range water-repellent coating treatments commonly use C6 or C8 PFOA/PFOS chemistry. No public statement from Columbia ruling this out. Graded separately (20/100) but drives the core safety concern.
Formaldehyde-based fabric finishing resins
Nylon and polyester do not inherently require formaldehyde resins for dye-setting or wrinkle resistance. No recalls or complaints specific to Cassiar Pro suggest finishing is standard; nylon naturally resists wrinkles. Risk is minimal for this product type.
Azo dyes (carcinogenic azo compounds)
Columbia products are not on record for azo-dye violations. Polyester and nylon accept modern disperse dyes without requiring banned azo chemistries. No hazard identified for this jacket.
Antimony (catalyst in polyester synthesis)
Antimony oxide is a standard catalyst in commercial polyester production and leaves trace residues in fiber. Documented leaching only occurs at elevated temperatures (>60C continuous wear) unlikely in normal outdoor jacket use. Risk is low but not zero; wash in cool water to further minimize any potential mobilization.
Microplastic shedding from coating degradation
As ODX coating weathers and flakes, fine synthetic particles may shed into wash water or air. Quantity and health impact are not well quantified for outdoor clothing; this is a plausible exposure pathway but not documented as a clinical hazard for waterproof jackets specifically.
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.
