Columbia Men's Pitchstone Outdoor Pants
High risk; outdoor pants with water-repellent coating treatment carry PFAS risk without Columbia chemistry details.
These nylon pants use a water-repellent coating finish typical of outdoor apparel historically linked to PFAS treatments. Columbia makes no public disclosure about PFAS content or safer alternatives.

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
water-repellent coating finishes on outdoor apparel are historically PFAS-based; Columbia does not disclose chemistry. Exposure risk is inhalation during manufacturing and handling, and potential skin contact during wear. Fluorine-free alternatives exist but are not confirmed in this product.
Source: ATSDR ↗Formaldehyde / VOCs
Some water-repellent coating and wrinkle-resistant finishes use formaldehyde-based chemistry. Columbia does not disclose finish type. Standard outdoor apparel formulations minimize formaldehyde, but absence of disclosure prevents confirmation.
Source: ATSDR ↗Microplastic shedding
Nylon apparel sheds microfibers during wash and wear. The Pitchstone pants will release synthetic fibers into waterways; this is a known property of nylon textiles, not unique to this brand or product.
What’s reassuring
Azo dyes
No public reports of restricted azo dyes (anilines) in Columbia nylon apparel. Industry standard testing and EU/US regulations make this unlikely, but not explicitly certified for this SKU.
Antimony in synthetic fibers
Antimony is a polyester catalyst and is not used in nylon fiber production. Not applicable to this product.
The full breakdown
What it's made of and why it matters
The Pitchstone pants are nylon with a water-repellent coating (water-repellent coating) finish. Nylon itself is stable and does not leach monomers or BPA under normal wear. The water-repellent coating is the material of concern: most outdoor apparel brands apply fluorochemical water-repellent coating (PFAS-based) or, increasingly, fluorine-free alternatives. Columbia has not publicly disclosed which chemistry they use in this product line, leaving the PFAS status uncertain.
The brand's record and disclosure
Columbia Sportswear has faced pressure on PFAS use in outdoor gear but has not published a comprehensive chemical inventory or phase-out timeline comparable to brands like Patagonia or Arc'teryx. The company does not disclose water-repellent coating chemistry on product labels or websites. This silence is typical of mid-market outdoor brands and reflects industry-wide opacity on fluorochemical use rather than Columbia-specific malfeasance, but it means buyers cannot verify whether this product contains PFAS.
How it compares in its category
Entry-level hiking pants from major brands (Columbia, The North Face, REI Co-op) generally do not disclose water-repellent coating chemistry. Premium alternatives like Patagonia and Arc'teryx publish fluorine-free commitments and are phasing out PFAS. Columbia's Pitchstone occupies the middle ground: competitively priced, widely available, but offering no transparency advantage over direct competitors. If PFAS avoidance is a priority, fluorine-free certified brands are a clearer choice.
If you buy it
Wash separately from other fabrics on cold water to minimize any potential leaching and protect the water-repellent coating finish. Avoid dry cleaning, which can degrade coatings and expose you to solvents. Do not tumble dry on high heat; hang dry instead. Re-treat with a water-repellent coating spray (read the product label for chemistry) every 1-2 seasons if water beading decreases. Discard if seams fail or coating flakes visibly, as breakdown can increase skin contact with finish materials.
