Patagonia Men's Sunrise Stream Shirt
Moderate concern from typical water-repellent coating treatment likely containing PFAS.
The Sunrise Stream Shirt uses nylon ripstop treated with water-repellent coating, historically a PFAS-based chemistry category. Patagonia does not disclose PFAS use or claim PFAS-free treatment.

Material
Nylon ripstop with 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 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.
water-repellent coating durability and reapplication safety
The water-repellent coating finish will wear out and may flake or generate microparticles with aggressive laundering. Commercial reproofing products vary in formulation; fluorine-free alternatives are safer but may require more frequent reapplication. Clarify product instructions if you choose to reproof.
What’s reassuring
Azo dyes and synthetic colorants
Nylon ripstop in standard commercial production may use azo dyes, which are restricted in some jurisdictions but are not banned by Patagonia or listed as a known problem in this product line. No recalls or warnings on record.
Formaldehyde / VOCs
Wrinkle-free and water-resistant finishes sometimes incorporate formaldehyde-release resins; nylon ripstop typically does not require this treatment because nylon inherently resists wrinkles. No evidence this shirt uses formaldehyde finishes, and no disclosures suggest otherwise.
Source: ATSDR ↗Heavy metals
Patagonia's manufacturing standards generally exclude lead and cadmium in textiles. No recalls or test failures documented for this product. Nylon ripstop in neutral or dark colors is not known to carry elevated heavy metal risk.
Source: FDA ↗Flame retardants
Nylon ripstop is not a common application for antimony catalysts or added flame retardants. This shirt is not marketed as flame-resistant and is not subject to flame retardant requirements. No reports of relevant additives in Patagonia nylon apparel.

What it's made of and why it matters
This shirt is constructed from nylon ripstop, a lightweight synthetic fabric treated with a water-repellent coating (water-repellent coating) finish. Nylon itself is a polyamide plastic that does not leach monomers under normal wear conditions. The water-repellent coating finish is the active concern: historically most commercial water-repellent coating treatments rely on fluorinated compounds (PFAS) to achieve water resistance without adding bulk. Patagonia has not disclosed whether this specific shirt uses legacy PFAS-based water-repellent coating, newer fluorine-free alternatives, or a hybrid approach.
The brand's record and disclosure
Patagonia is recognized for environmental commitments and has made public statements about reducing PFAS in some product lines, particularly in wetsuits. However, the company does not provide product-level water-repellent coating transparency on most apparel and has not published a complete PFAS-free shirt line for this category. No formal certifications (Bluesign, GOTS, OEKO-TEX MADE IN GREEN) are listed for this specific garment, which limits third-party verification of treatment chemistry. The lack of explicit 'PFAS-free water-repellent coating' labeling is a disclosure gap rather than evidence of a known hazard.
How it compares in its category
Wrinkle-free and water-resistant dress shirts typically use either Teflon-type coating (Teflon-like) coatings or fluorinated water-repellent coating finishes; this nylon ripstop shirt falls into the latter camp. Patagonia's approach is mainstream for performance dress shirts. True PFAS-free alternatives exist (some brands now use wax-based or silicone water-repellent coating, or omit water-repellent coating altogether), but they are less common in the ripstop nylon dress shirt space. This product is not an outlier, but it also does not represent a proactive shift toward transparent chemistry.
If you buy it
Nylon ripstop is durable and will not degrade significantly with regular washing or sun exposure. Wash in cool to warm water; avoid prolonged heat (dryer on low or hang dry) to preserve both the fabric and the water-repellent coating finish. The water-repellent coating will gradually diminish with use and laundering, typically lasting 20-40 wears depending on care. If water resistance remains important to you, reproof with a non-PFAS water-repellent coating treatment (silicone or wax-based options are commercially available) rather than replacing the shirt. Do not dry clean unless explicitly labeled as safe.
