Columbia Men's Silver Ridge Convertible Pant
High risk; outdoor pants with water-repellent coating, PFAS risk unclear without disclosure.
These nylon/polyester pants have a water-repellent coating finish typically treated with PFAS. Columbia does not publicly disclose whether this model uses PFAS-free water-repellent coating.

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
water-repellent coating degradation and leaching
As the fluorocarbon or alternative water-repellent coating finish wears with washing and use, breakdown products may shed into water or skin contact. No specific degradation timeline is published for this model. Extent of leachable material depends on the exact chemistry, which Columbia has not disclosed.
Microplastics
Nylon and polyester garments shed microfibers, especially during washing and abrasion from trail use. The degree depends on weave tightness and finish; this pant's construction is typical for the category. Microfiber release is not specific to this brand but is inherent to the material class.

Azo dyes and colorant stability
No specific safety alerts or recalls document harmful azo dyes in Columbia Silver Ridge products. Industry standard testing and bluesign certification (where applied) typically screen for azo dye violations, though Columbia has not transparently confirmed azo-dye testing for this line.
Formaldehyde / VOCs
Modern nylon and polyester blends sometimes use formaldehyde-containing resins to stabilize color and wrinkle resistance. No public data suggests Columbia uses such resins in the Silver Ridge, but the company has not explicitly ruled this out. Off-gassing risk from outdoor apparel worn on skin is considered low in standard assessment.
Source: ATSDR ↗Heavy metals
No documented contamination of Columbia hiking wear with lead, cadmium, or other heavy metals in colorants. Standard textile industry oversight and bluesign participation suggest screening, but full transparency is absent.

What it's made of and why it matters
The Silver Ridge Convertible combines nylon and polyester with a water-repellent coating (water-repellent coating) finish. The nylon provides abrasion resistance for trail contact; polyester adds durability and quick-dry properties. The water-repellent coating is the critical unknown: Columbia has not publicly disclosed whether this finish contains PFAS compounds like Teflon-type coating or fluorocarbon-based repellents, which are common in outdoor apparel but increasingly linked to environmental and health concerns. Modern alternatives like wax-based or silicone-based water repellents exist but are not standard industry-wide.
The brand's record and disclosure
Columbia Sportswear has not issued a formal public commitment to eliminate PFAS from its product lines, unlike some competitors (Arc'teryx, Patagonia). The company has not transparently disclosed the chemical composition of water-repellent coating treatments across its catalog. Columbia does maintain certifications like bluesign approval on some products, but this does not exclude PFAS use. No major recalls or safety alerts specific to the Silver Ridge line have been documented.
How it compares in its category
Within hiking pants, the Silver Ridge is mid-market. Many competitors in the same price range use identical nylon/polyester blends with undisclosed water-repellent coating chemistry, so this product is representative rather than an outlier. Some premium brands (Patagonia, Fjallraven) now offer PFAS-free water repellent alternatives, though they command higher prices. Budget alternatives often use lower-durability synthetic blends without water repellency or with older, cheaper PFAS-based coatings.
If you buy it
Wash in cool water with mild detergent; avoid chlorine bleach and fabric softeners, which can degrade water-repellent coating performance and potentially mobilize coatings. Do not dry clean or expose to prolonged high heat (above 60°C), as this can accelerate coating degradation and shedding. Reapply water-repellent coating treatment every 1-2 years if water no longer beads on the fabric. If PFAS disclosure remains unavailable and this concerns you, contact Columbia directly or consider brands with published PFAS-free certifications.
