Columbia Men's Silver Ridge Utility Pants - Size 44 - Green
High risk; Columbia's silence on water-repellent coating chemistry is concerning, ask for treatment details before purchase.
Columbia does not publicly disclose the water-repellent coating chemistry on these nylon/polyester utility pants. water-repellent coating finishes historically relied on PFAS, though some brands now use fluorine-free alternatives.

Material
nylon/polyester blend with water-repellent coating (water-repellent coating) treatment
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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.
PFAS
Undisclosed water-repellent treatment on nylon/polyester blends historically uses PFAS fluorochemicals; Columbia's silence on formula is a strong indicator of legacy chemistry. PFAS bioaccumulates and is linked to immune and liver effects.
Source: ATSDR ↗Antimony in polyester fiber
Polyester production may use antimony as a catalyst; small residual amounts can remain in fibers. Exposure risk during normal wear is minimal, but repeated skin contact in warm conditions theoretically increases dermal absorption. No incidents reported for this product.
Microplastic shedding during wear and wash
Nylon and polyester shed microfibers during washing and abrasion. While primarily an environmental concern, inhaled or ingested microplastics from contaminated water are an emerging health question. Wear and launder these pants normally; microplastic generation is unavoidable with synthetic textiles.
What’s reassuring
Formaldehyde / VOCs
No public record of formaldehyde-based finishes or dye-release issues in Columbia Silver Ridge apparel. Standard industry controls typically limit residual formaldehyde in finished textiles to safe levels.
Source: ATSDR ↗Heavy metals
No recalls or documented incidents of cadmium, lead, or restricted azo dyes in Columbia hiking pants. Green colorants in synthetic sportswear are generally well-regulated.

What it's made of and why it matters
These pants are a nylon/polyester blend, both synthetic polymers that are chemically stable during normal wear. The critical unknown is the water-repellent coating (water-repellent coating) finish applied to the exterior, which historically relied on PFAS-based fluorochemicals to repel water and stains. Columbia has not publicly committed to PFAS-free water-repellent coating formulations, leaving the chemical identity of this treatment opaque. Nylon and polyester themselves do not leach hazardous substances under typical hiking conditions, but the finish chemistry directly affects overall safety.
The brand's record and disclosure
Columbia Sportswear does not maintain a public inventory of chemical treatments or water-repellent coating suppliers for specific SKUs, and has not signed the ZDHC (Zero Discharge of Hazardous Chemicals) Gateway or similar transparency pledges. The brand has faced no major product recalls tied to formaldehyde or heavy metals in apparel, suggesting baseline manufacturing controls are in place. However, their silence on fluorochemical policy contrasts with competitors like Patagonia and The North Face, which explicitly disclose PFAS-free or PFAS-reduction initiatives. This opacity is the primary red flag.
How it compares in its category
Hiking pants in this price and durability tier typically use either PFAS-based water-repellent coating (most common, lowest cost), PFC-free alternatives (polyurethane or fluorine-free polymers, increasingly standard), or no water-repellent treatment. Columbia's Silver Ridge line occupies the middle market, where PFAS use remains industry-standard despite growing alternatives. Competitors like REI Co-op and Outdoor Research have shifted to disclosed non-PFAS or PFAS-reduced water-repellent coating on comparable pants, making Columbia's lack of transparency a relative weakness in this category.
If you buy it
Contact Columbia customer service or check product tags for water-repellent coating supplier or chemistry details before purchase; if they cannot disclose, assume legacy PFAS-based treatment. Wash separately from other clothing in cold water before first wear to remove loose finish residues. Do not tumble-dry on high heat (nylon can degrade; excess heat may re-mobilize finish chemicals into fibers). Replace or retire the pants when seams fail or water-repellent coating visibly degrades (beading stops, water no longer sheets off); do not attempt to re-treat with commercial water-repellent coating sprays unless they are explicitly PFAS-free.
