Columbia · Stain-Resistant Footwear
Ralyn Aquatec
Apparel with water-repellent coating treatment, PFAS risk unclear. Columbia does not disclose.
Ralyn Aquatec is a water-repellent polyester jacket. Columbia provides no public information about PFAS in the water-repellent coating finish; standard industry practice raises concern.

The full breakdown
What it's made of and why it matters
Ralyn Aquatec is polyester with a water-repellent coating (water-repellent coating) finish. Polyester itself is a synthetic polymer with low inherent toxicity, but the water-repellent coating is the concern: Columbia has not disclosed whether it uses PFAS-based chemicals (like Teflon-type coating) or fluorine-free alternatives. Over time and with washing, water-repellent coating coatings can degrade, potentially releasing microfibers into water. Polyester microfiber shedding increases with mechanical stress such as friction or machine washing.
The brand's record and disclosure
Columbia Sportswear does not publicly commit to PFAS-free water-repellent coating treatments across its product lines, nor does it provide material safety documentation for individual products like Aquatec. The brand has faced no major publicized recalls or hazard notices for this line, but the silence on chemical disclosure is notable given industry movement toward transparency. Competitors including The North Face and Patagonia have begun disclosing or phasing out PFAS-based finishes; Columbia's stance remains opaque.
How it compares in its category
Water-repellent apparel is common, and most brands use either PFAS-based or newer fluorine-free water-repellent coating coatings. Ralyn Aquatec sits in a mid-range outdoor/casual segment where disclosure is inconsistent across the industry. Polyester base material is standard and poses lower toxicity risk than untreated cotton blends or heavily dyed fabrics, but the unknown water-repellent coating chemistry is a differentiator and a source of uncertainty relative to brands with published chemical commitments.
If you buy it
Wash in cold or warm water (below 60°C/140°F) to preserve the water-repellent coating and minimize microfiber shedding. Use a mesh laundry bag to reduce fiber release into waterways. Avoid prolonged heat (tumble dry on low or air dry) as heat can degrade the coating and potentially volatilize treatment chemicals. Replace when water beading visibly fails or after 50+ washes; do not attempt to re-coat at home without knowing the original chemistry.
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.”
Polyester microfiber shedding
Polyester apparel sheds microfibers during wear and washing, especially with mechanical stress. This is not a health hazard to the wearer but a documented environmental concern. Using a wash bag and low-temperature laundering reduces shedding.
water-repellent coating durability and degradation
The water-repellent finish will degrade over time and with washing. Degraded coatings may release particulates or, if PFAS-based, mobilize residual chemicals. Columbia's non-disclosure makes it impossible to assess degradation byproducts.
Formaldehyde resins in polyester processing
Standard polyester manufacturing may involve trace formaldehyde resins, but finished apparel typically contains negligible residual levels if properly rinsed. No specific recall or hazard notice has been issued for Columbia Ralyn Aquatec.
Azo dyes in polyester coloring
If Ralyn Aquatec is dyed (e.g., dark colors), it may contain azo dyes. Restricted azo dyes are banned in most markets, but non-restricted azo dyes can break down and release aromatic amines under sweat, heat, or stomach acid. Columbia does not provide dye safety certifications for this line.
Undisclosed water-repellent chemistry (PFAS or alternative)
Columbia does not disclose whether Ralyn Aquatec uses PFAS or fluorine-free water-repellent coating. This is separate from the PFAS grade but affects overall chemical safety assessment. Fluorine-free alternatives carry lower bioaccumulation risk but may have other hazards not yet widely studied.
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.
