Patagonia Men's Home Waters Hybrid Shorts
Lower concern. Patagonia phased out PFAS-based water-repellent coating; verify current product line batch.
Patagonia committed to eliminating PFAS-based water-repellent coating treatments across its apparel. This hybrid short uses alternative water-repellent chemistry, though full transparency on alternative compounds varies by production year.
Brand says: “Patagonia has committed to PFAS-free durable water repellent treatments and has phased out PFC-based DWR coatings from its product line.”

The full breakdown
What it's made of and why it matters
These shorts are a polyester blend (likely 88% polyester, 12% spandex or similar elastane based on typical Patagonia construction) with a water-repellent coating (water-repellent coating) finish applied to the outer shell. Patagonia has publicly committed to phasing out legacy PFAS-based water-repellent coating treatments and now uses non-fluorinated alternatives like fluorine-free wax or silicone-based coatings. The polyester itself is inherently resistant to moisture and does not degrade into microplastics under normal wear or machine washing at standard temperatures.
The brand's record and disclosure
Patagonia has documented its transition away from PFAS-based water-repellent coating finishes across its product lines since the mid-2010s and publishes regular corporate responsibility reports detailing chemical use. The company is a signatory to the Detox Commitment and maintains third-party certifications including bluesign and Fair Trade equivalencies. No recalls or major chemical safety controversies have been reported for this shorts model. Patagonia's supply chain transparency is considered industry-leading for mid-premium outdoor apparel.
How it compares in its category
Most hybrid shorts in this price and performance tier still rely on legacy PFAS-based water-repellent coating, making Patagonia's fluorine-free option a lower-chemical choice. Budget competitors often use untested or undisclosed water-repellent coating formulations, while premium alternatives (Arc'teryx, Outdoor Research) are similarly transitioning away from PFAS. The polyester+spandex blend is standard for this category and poses no chemical hazard advantage or disadvantage versus competitors.
If you buy it
Machine wash in cool to warm water (not hot); heat above 60 degrees Celsius can degrade the water-repellent coating finish and is unnecessary for hygiene. Avoid chlorine-based detergents and fabric softeners, which strip the water-repellent coating. The water-repellent coating treatment typically lasts 50 to 100 wash cycles; you can reapply commercial fluorine-free water-repellent coating products if water beading diminishes. Normal care poses no inhalation or skin contact risk from the applied finish.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Azo dyes
Patagonia materials are bluesign certified, which restricts azo dyes known to produce carcinogenic amines. No azo dye contamination has been reported for this product.
Formaldehyde resins in fabric finishing
Patagonia does not use formaldehyde-release finishes on polyester apparel. The water-repellent coating and any elastane recovery treatments use non-formaldehyde chemistries.
Antimony in polyester fiber
Polyester manufacturing can use antimony trioxide as a catalyst; Patagonia does not publicly disclose antimony residue testing. Levels in finished textiles are typically <100 ppm and pose no acute risk during normal wear, but cumulative exposure from frequent handling or heating is not ruled out.
Flame retardants
Hybrid shorts are not required to meet children's sleepwear flammability standards and do not carry added flame retardants. No flame retardant additives are standard in performance polyester apparel of this type.
Microplastic shedding from polyester
Polyester textile fibers shed microplastics during washing and wear, particularly with abrasion. This is an environmental concern rather than a direct wearer health hazard, but high-wash-frequency users should be aware of cumulative microfiber release.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
Formulations and coatings change between production runs. Always check the current label before buying.
