Patagonia Men's Insulated Storm Shift Ski/Snowboard Pants
A water-repellent or grease-resistant treatment of unstated chemistry, with a brand PFAS statement we have not verified.
Patagonia says 100% of its new products from Spring 2025 are made without intentionally added PFAS. We record that as an unverified brand claim. Its record describes a water-repellent or grease-resistant treatment of unstated chemistry, which is still counted.

What Patagonia Men's Insulated Storm Pants is made of, ingredients and materials
The shell is polyester with an applied water-repellent coating (water-repellent coating) finish; the insulation type and lining materials are not specified in available product information. Polyester itself is chemically stable and does not off-gas formaldehyde or volatile organics under normal wear. However, the water-repellent coating chemistry is the critical unknown, Patagonia claims PFAS-free status, but the specific replacement chemistry (likely fluorine-free or hydrocarbon-based) has not been publicly detailed, making independent verification impossible.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
water-repellent coating (water-repellent coating) treatment composition
Patagonia claims PFAS-free water-repellent coating but has not publicly disclosed the specific alternative chemistry (fluorine-free or hydrocarbon-based). Unconfirmed formulations carry uncertain long-term skin contact and laundering effects.
Flame retardants
The insulation type and any flame-retardant treatment are not disclosed in available product specifications. Many ski pants use synthetic insulation that may contain halogenated or non-halogenated flame retardants; clarification from the brand is needed.
Source, EPA ↗water-repellent coating reapplication products (user-applied)
Over-the-counter water-repellent coating recoatings often contain PFAS or other volatile solvents. If you use them, verify the product label and choose PFAS-free alternatives to avoid undoing the garment's claimed safety profile.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Polyester antimony catalyst residue
Polyester production may involve antimony oxide catalysts; no recalls or test data specific to Patagonia apparel indicate migration or exposure risk under normal wear.
Azo dye contamination
Color treatments in polyester snowwear can include azo dyes; Patagonia does not advertise azo-free status, but no established safety incidents or contamination reports are on record for this brand's color fastness.
How is this PFAS grade calculated?
The brand's record and disclosure
Patagonia has committed to eliminating PFAS from water-repellent coating treatments and published a stance on this issue, but has not released detailed third-party test results or specified which lower-concern chemistry is used in this product line. The company is generally recognized for environmental and labor accountability, though transparency on chemical substitutes in apparel remains limited across the industry. No major safety recalls or substantiated contamination reports specific to this product model are publicly available.
How it compares in its category
Most premium ski pants still use Teflon-type coating (Teflon) or PFC-based water-repellent coating finishes; Patagonia's claimed shift away from PFAS places this product ahead of many competitors in hazard profile, though proof of the alternative chemistry is lacking. Budget alternatives often use lower-durability synthetic water-repellent coating that degrades faster and may require reapplication. High-end alternatives from other brands (Arc'teryx, The North Face) vary widely in transparency and PFAS status depending on the specific product.
If you buy it
Wash in cold water with mild detergent and hang dry; avoid heat drying, which can degrade both the polyester shell and the water-repellent coating finish prematurely. Do not dry-clean or use bleach. Reapply water-repellent coating every 2-3 seasons or when water beading diminishes, and confirm the replacement product matches the brand's PFAS-free standard. Store in a cool, dry place away from direct sunlight to extend lifespan of both shell and insulation.
