Patagonia Men's Torrentshell 3L Rain Pants
High risk. High-performance rain gear likely contains legacy or replacement PFAS in water-repellent coating. Patagonia's silence is a red flag.
Torrentshell 3L uses nylon with a water-repellent coating finish, a product category historically reliant on PFAS-based coatings. Patagonia has made limited public commitments on PFAS elimination for apparel.

Material
Nylon 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
Torrentshell 3L uses water-repellent coating finish; Patagonia's failure to disclose specific water-repellent coating chemistry on this product makes it highly likely to contain some fluorinated compound (either legacy PFAS or newer alternatives). water-repellent coating coatings release fluorinated compounds during washing and wear.
Source: ATSDR ↗Nylon microfiber shedding during washing
Synthetic fabrics including nylon release microplastics into wastewater during laundering. Rain pants with multiple washes over a season contribute measurable microfiber load; this is not unique to Patagonia but is inherent to the material class.
water-repellent coating degradation and reapplication exposure
As the water-repellent coating wears, users typically reapply commercial water-repellent coating treatments, many of which contain PFAS or other fluorinated compounds. Improper reapplication can create skin contact exposure if product-specific instructions are not followed closely.
What’s reassuring
Formaldehyde / VOCs
Patagonia's supply chain audits and dyeing standards are documented as stringent; no public recalls or safety concerns have been raised regarding formaldehyde in Torrentshell products. Industry standard for high-end nylon apparel includes restricted-use dyes, and Patagonia's manufacturing certifications typically exclude problematic azo dyes.
Source: ATSDR ↗Flame retardants
Rain pants are not regulatory targets for flame retardants (that applies mainly to furniture and sleepwear). Nylon used in technical apparel does not typically contain added flame retardants; no evidence or disclosure suggests Torrentshell includes them.

What it's made of and why it matters
The Torrentshell 3L uses nylon fabric (polyamide) with a water-repellent coating (water-repellent coating) coating applied to the outer shell. water-repellent coating treatments historically relied on long-chain PFAS (perfluorooctanoic acid and similar compounds) and increasingly on replacement PFAS or fluorine-free alternatives. Patagonia has not publicly disclosed which water-repellent coating chemistry is used in this specific product, which is a significant transparency gap given known PFAS contamination of legacy rain gear. The nylon itself is chemically stable and poses no inherent leaching risk; the concern is entirely the finish.
The brand's record and disclosure
Patagonia has a strong environmental reputation and has committed to phasing out long-chain PFAS in some product lines, but the company has not published a complete PFAS inventory or timeline for all rain apparel products, including the Torrentshell line. The brand does excel in transparency on manufacturing practices, supply chain audits, and repair/recycling (Worn Wear program), which partially mitigates chemical concerns through product longevity. However, silence on a widely documented chemical hazard in rain gear is inconsistent with Patagonia's stated environmental ethics and leaves consumers unable to make fully informed choices.
How it compares in its category
Most 3-layer rain pants in the high-performance outdoor category (Arc'teryx, The North Face, Columbia) contain PFAS-treated water-repellent coating coatings, making this a category-wide problem rather than brand-specific failure. Patagonia's durability, repairability, and use-longevity actually reduce environmental footprint per wear compared to cheaper rain gear that fails sooner. Fluorine-free water-repellent coating alternatives (used by some brands like Fjallraven) exist but sacrifice water-beading performance and durability in harsh conditions; none are yet industry standard for high-end technical rain apparel.
If you buy it
Wash infrequently (water-repellent coating coatings shed microfibers and any treatment residues with each wash); use cold water and air dry rather than machine drying, which can degrade the membrane. Reapply water-repellent coating annually if water no longer beads, using a fluorine-free water-repellent coating product (Eden, Grangers, or similar) to limit additional PFAS exposure over time. Plan for 5-10 years of active use; Patagonia's repair service and Worn Wear resale extend usable life. If PFAS concern is acute, consider buying used via Worn Wear (existing coating already present, no new exposure) or requesting product-specific water-repellent coating chemistry disclosure before purchase.
