Arc teryx Skyline Shirt Men's
Arc'teryx silent on PFAS in water-repellent coating treatments; moderate concern.
The Skyline Shirt uses standard water-repellent coating finishes typical of performance apparel, likely containing fluorochemicals. Arc'teryx provides no public PFAS disclosure or commitment.

The full breakdown
What it's made of and why it matters
The Skyline Shirt is a polyester/nylon blend, both synthetic polymers that are chemically stable and do not leach monomers under normal wear conditions. The water-repellent (water-repellent coating) coating applied to the fabric is the material of concern. Arc'teryx does not publicly specify whether their water-repellent coating treatment uses PFAS-based chemistry (common in performance apparel) or fluorine-free alternatives. The coating's durability and potential degradation over time, especially with washing and heat exposure, determines whether any coating materials could migrate.
The brand's record and disclosure
Arc'teryx is a subsidiary of Salomon (owned by Kering/Gucci Group) and has not published specific information about PFAS avoidance, phase-out timelines, or third-party certifications for water-repellent coating treatments on this product line. The brand maintains no public PFAS commitment comparable to some outdoor apparel competitors. This silence is notable in a category where PFAS disclosure has become increasingly standard among tier-one manufacturers.
How it compares in its category
Performance outdoor shirts typically use PFAS-based water-repellent coating (polyfluorinated compounds) or emerging fluorine-free alternatives (like hydrocarbon-based or polyurethane systems). Arc'teryx occupies the premium segment where both approaches appear, but their lack of transparency makes direct comparison difficult. Competitors like Patagonia and some Salewa lines explicitly market PFAS-free water-repellent coating; Arc'teryx does not.
If you buy it
Wash in cool water with neutral detergent to minimize coating stress and potential migration. Avoid high heat (dryer, ironing, direct sun for extended periods) as water-repellent coating coatings degrade faster at elevated temperatures. The water-repellent coating will lose effectiveness within 20-50 washes depending on care; reapplication products exist but reintroduce the same unknown PFAS exposure. If PFAS exposure is a priority concern, request material safety data or seek brands with explicit fluorine-free certifications.
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.”
PFAS in water-repellent coating finish (fluorinated water-repellent coating)
Arc'teryx does not disclose water-repellent coating chemistry. PFAS-based water-repellent coating treatments are industry standard in premium apparel but not guaranteed in this product. Migration risk increases with washing, heat, and aging.
Azo dyes (synthetic colorants)
Polyester apparel from major brands typically uses regulated azo dyes that do not release carcinogenic amines under normal use. No safety incidents or warnings are on record for Arc'teryx apparel.
Antimony in polyester (catalyst residue)
Antimony is occasionally used as a catalyst in polyester polymerization but is retained within polymer chains and does not migrate during wear or washing. Public health concern is minimal in finished garments from established manufacturers.
Formaldehyde in synthetic textiles
Formaldehyde resins are used primarily in cotton and blended fabrics for wrinkle resistance. Pure or dominant polyester/nylon blends like this shirt typically contain minimal formaldehyde unless treated for shrinkage control, which is not standard for Arc'teryx performance apparel.
water-repellent coating durability and degradation
All water-repellent coatings degrade with washing and heat. As the coating fragments, microparticles of the coating material may shed; if PFAS-based, this represents a cumulative exposure pathway over the garment lifetime.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
