Patagonia Men's M10 Anorak
water-repellent coating treatment likely contains PFAS; Patagonia silent on composition.
Patagonia M10 Anorak uses nylon with water-repellent finish typical of synthetic water-repellent coating coatings often containing PFAS. Brand makes no disclosure about PFAS content or alternatives used.

Material
Nylon with water-repellent coating (water-repellent coating) finish
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Heavy metals
Nylon fabrics can be colored with various dye classes. Patagonia's manufacturing audits and certifications do not specifically exclude or test for trace cadmium or lead in finished textiles for this model. Risk is low if sourced from regulated suppliers, but no third-party test data is public.
Source: FDA ↗water-repellent coating finish degradation and microrelease
water-repellent coating coatings degrade with wear and washing, shedding fine particulates into wash water and the environment. Whether this product sheds PFAS or other water-repellent coating-polymer fragments at higher rates than industry standard is not independently tested.
Nylon microfiber shedding during laundering
Synthetic nylon textiles release microfibers in wash cycles. This anorak, like all nylon garments, will shed fibers; the quantity and lifecycle impact are not quantified by Patagonia or independent labs for this specific model.
What’s reassuring
Azo dyes in nylon
Patagonia does not publicly disclose dye sourcing or azo restrictions for this product. Nylon dyeing can use azo compounds, but no independent testing or recalls specific to this anorak have been reported.
Formaldehyde / VOCs
Nylon does not require formaldehyde-based wrinkle-resist treatments. The water-repellent coating finish chemistry is proprietary and not disclosed; formaldehyde is unlikely but possible as a component in some industrial water-repellent coating formulations.

What it's made of and why it matters
The M10 Anorak is constructed from nylon fabric treated with a water-repellent coating (water-repellent coating) finish. water-repellent coating treatments on nylon are typically applied as chemical coatings to create water beading and repellency without changing breathability. Nylon itself is a synthetic polymer that does not off-gas formaldehyde or volatile organics in normal wear, but the water-repellent coating finish is the primary chemical concern in this product's lifecycle.
The brand's record and disclosure
Patagonia has published environmental commitments and uses third-party certifications like the Responsible Wool Standard on some products, but does not publicly disclose water-repellent coating chemistry or PFAS content for this anorak. The brand has not released statements confirming fluorine-free water-repellent coating alternatives on nylon pieces, leaving composition opaque. Industry reporting indicates Patagonia has explored alternative water repellents but adoption across lines remains inconsistent and unannounced.
How it compares in its category
Most nylon rain jackets in this price and performance tier use water-repellent coating finishes, many with PFAS-based formulations. Some competitors (e.g., Arcteryx, The North Face) have begun labeling fluorine-free water-repellent coating options on specific models, whereas Patagonia offers no such transparency on the M10. The durability and repairability infrastructure Patagonia offers (Worn Wear program) does offset faster obsolescence compared to fast-fashion alternatives, reducing cumulative exposure per wear cycle.
If you buy it
Wash infrequently in cold water and air-dry; hot water and dryers can degrade water-repellent coating coatings and potentially mobilize residual finish chemicals. Do not dry-clean, as solvents may alter polymer structure. Reapply commercial water-repellent coating treatments sparingly, and research the formulation of any aftermarket product you use. The jacket's warranty and repair program make it a long-wear piece, so purchase assumes multi-year use to amortize embedded chemical exposure.
