Patagonia Men's Sunrise Stream Shirt
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 Sunrise Stream Shirt is made of, ingredients and materials
This shirt is nylon ripstop, a lightweight synthetic polymer woven with reinforcing crossthreads to resist tearing. It carries a water-repellent coating (water-repellent coating) finish applied during manufacturing to shed water without heavy coatings. Nylon itself is chemically stable in normal use and does not leach known toxins into skin under typical wearing conditions. However, the chemistry of the water-repellent coating treatment is the critical unknown, Patagonia's PFAS-free claim is stated but not independently verified, and the actual repellent compound used is not disclosed in available product information.
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 finish chemical composition (unverified)
The water-repellent treatment is not chemically named in product documentation. While Patagonia claims PFAS-free status, independent verification of the specific formula on this model is not available in public records, leaving the actual repellent compound uncertain.
Microplastics
Nylon garments shed microfibers during washing, particularly in the first 5-10 wash cycles and if the fabric is damaged. This is not unique to this brand or product but is a systemic issue with synthetic ripstop textiles. Using a washing machine filter bag and washing less frequently can reduce shed volume.

Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Formaldehyde / VOCs
Nylon ripstop does not typically require formaldehyde-based wrinkle-resist treatments; wrinkle-free claims on nylon are usually mechanical (ripstop weave) or via the water-repellent coating process itself. No formaldehyde resins are named or known in connection with this product line.
Source, ATSDR ↗Heavy metals
Patagonia has established sourcing standards and testing for azo dyes and metal content in colorants across its apparel lines. No recalls or test failures on this shirt for dye-related toxins are on record.
Source, FDA ↗Flame retardants
This shirt is nylon ripstop, not polyester, and does not require added flame retardants for consumer apparel. Antimony is not relevant to nylon composition.

The brand's record and disclosure
Patagonia has publicly committed to eliminating PFAS from all products and has published detailed sustainability reports naming water-repellent coating suppliers and testing protocols for some garment lines. However, this specific shirt's water-repellent coating formula has not been independently audited or certified by third parties in publicly available records. The brand's overall environmental track record and willingness to disclose supply chain details is stronger than industry average, but the PFAS claim for this product line specifically remains unverified by the sources available. Buyers relying on the claim should note that verification is pending.
How it compares in its category
Wrinkle-free and water-repellent dress shirts typically rely on either PFAS-based treatments (standard and cheaper) or newer fluorine-free alternatives (increasingly common in premium brands). Patagonia's positioning in the fluorine-free segment is credible given the brand's stated direction, but this shirt occupies a middle ground of stated intent without third-party proof. Comparable alternatives from outdoor brands like Arc'teryx and some REI house lines offer comparable water-repellent coating performance with more transparent chemical disclosure or third-party certification (e.g., Bluesign or GOTS). Standard retail dress shirts are far more likely to use legacy PFAS treatments without any disclosure.
If you buy it
Wash in cool water with mild detergent and avoid fabric softeners, which can clog the water-repellent coating finish and reduce water repellency. Nylon is durable and does not require special heat precautions during normal home washing or air drying; do not use high heat from dryers as it can degrade both the fiber and any finish. The water-repellent coating will gradually wear with repeated washing and outdoor exposure; plan for reapplication of commercial water-repellent coating sprays every 5-10 wears if water shedding is critical to your use. Do not dry clean, as standard dry-cleaning solvents may strip or alter the finish.
