Patagonia Men's Trailfarer Shorts
Lower PFAS concern; Patagonia uses safer water-repellent coating alternatives.
Patagonia has shifted most apparel to PFOA-free, non-fluorinated water repellents. Trailfarer shorts use synthetic blend with updated water-repellent coating, reducing legacy PFAS risk.
Brand says: “Patagonia has committed to phasing out PFCs (PFAS) and moved to PFOA-free water repellent treatments in most apparel lines.”

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.
Polyester microfiber shedding during laundering
All polyester garments shed microfibers; the nylon blend may reduce this slightly compared to 100% polyester shorts. Shedding rate depends on fabric construction and wash intensity. This is not a safety hazard to the wearer but an environmental concern.
water-repellent coating degradation and reapplication products
As the original water-repellent coating wears, some users apply aftermarket water repellent treatments; quality and composition of these products varies widely. Patagonia-recommended treatments are vested in safer alternatives, but third-party products may introduce hazardous chemicals if not chosen carefully.
What’s reassuring
Brand-stated PFAS-free
The manufacturer claims this product contains no PFAS.
Formaldehyde / VOCs
No recalls or known issues reported for Patagonia's standard apparel lines; the brand uses restricted dye suppliers and Bluesign-certified finishing. Formaldehyde resins in durable finishes are present but at levels within industry and regulatory norms for outdoor wear.
Source: ATSDR ↗Antimony in polyester fiber
Antimony is used as a catalyst in some polyester production but remains encased in the polymer; skin migration is not documented in finished garment studies. No established risk from wearing antimony-containing polyester textiles.
Lead
Patagonia sources components to restricted substance lists; no recalls for nickel or heavy metal contamination in elastic waistbands or zipper hardware. This remains a lower-risk area for this brand's quality standard.

What it's made of and why it matters
These shorts are a nylon and polyester blend, both synthetic polymers chosen for durability, quick-dry performance, and stretch. The water-repellent coating (water-repellent coating) coating applied to the fabric is the critical component: Patagonia has committed to phasing out legacy PFAS-based water-repellent coating in favor of fluorine-free or lower-PFAS alternatives. The blend itself poses minimal chemical leaching risk under normal wear, though polyester can shed microfibers during washing.
The brand's record and disclosure
Patagonia has publicly committed to eliminating PFAS from its product lines and publishes detailed sustainability reports on chemical management. The company has faced scrutiny on water-repellent coating treatment in the past but has been transparent about reformulation timelines. Third-party certifications like Bluesign approval on some lines indicate chemical process oversight, though individual product certifications are not always published for every SKU.
How it compares in its category
Outdoor shorts in this price range typically use either Teflon-type coating-based water repellents or legacy PFAS-heavy water-repellent coating coatings. Patagonia's shift toward fluorine-free water-repellent coating puts these shorts ahead of commodity alternatives from fast-fashion brands. However, performance durability of newer water-repellent coating formulations is still being proven long-term; traditional PFAS alternatives have decades of field data.
If you buy it
Wash inside-out in cool water with gentle detergent to minimize microfiber shedding and preserve the water-repellent coating. Avoid fabric softeners and dryer heat, which degrade coatings; air-dry when possible. The water-repellent coating will diminish over repeated washing; reapplication with fluorine-free products (or manufacturer-approved treatments) extends durability. Replace when seams show stress or stretch loss, typically 2-3 years of regular use.
