Arc'teryx Sabre Relaxed Pant Men's
Uncertain due to undisclosed water-repellent coating chemistry; assume traditional PFAS-based treatment unless stated otherwise.
The Sabre Relaxed Pant uses nylon with a water-repellent coating typical of technical outdoor apparel. Arc'teryx hasn't disclosed whether their water-repellent coating finish is PFAS-free or traditional fluorocarbon-based.

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 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.
PFAS
Arc'teryx does not disclose water-repellent coating type; traditional fluorocarbon finishes contain PFAS, which may persist on the fabric and degrade into the wearer's environment. Exact formulation unknown; assume standard PFAS-based treatment unless product documentation specifies otherwise.

What’s reassuring
Formaldehyde / VOCs
No formaldehyde resin treatments are standard for nylon rain pants; nylon requires minimal chemical curing. No documented cases of formaldehyde issues in Arc'teryx nylon apparel.
Source: ATSDR ↗Heavy metals
Arc'teryx typically uses neutral or dark colorways (including the standard black/grey Sabre variants) that do not rely on known problematic dyes. No reported heavy metal contamination in Arc'teryx nylon textiles.
Source: FDA ↗Antimony in polyester components
The Sabre Relaxed Pant is nylon-based, not polyester, so antimony catalyst contamination is not a concern for the primary fabric. Any polyester in linings or trim would be minimal and is not documented as a hazard in Arc'teryx products.
The full breakdown
What it's made of and why it matters
The Sabre Relaxed Pant is constructed from nylon fabric with a water-repellent coating (water-repellent coating) finish. Nylon itself is a synthetic polymer that does not leach chemicals under normal wear conditions. However, the water-repellent coating treatment applied to the fabric is the critical unknown: Arc'teryx does not publicly specify whether this uses traditional fluorocarbon-based PFAS, newer fluorine-free alternatives, or a proprietary blend. This finish degrades over time and with washing, which is why the garment's safety profile can change during its lifespan.
The brand's record and disclosure
Arc'teryx has not made public commitments to PFAS-free water-repellent coating treatments or published chemical ingredient lists for their weather-resistant garments. The company maintains high standards for durability and performance but remains silent on the specific chemistry of water-repellent finishes across their product line. No major textile safety recalls or substantiated chemical contamination claims are documented for Arc'teryx apparel. This silence on water-repellent coating chemistry is common in the outdoor apparel industry but represents a disclosure gap for consumers seeking transparency.
How it compares in its category
Most rain pants in the $250-400 range (Arc'teryx's typical price tier) use either traditional PFAS-based water-repellent coating or proprietary fluorine-free treatments; Arc'teryx does not differentiate itself as PFAS-free. Brands like Patagonia and some retailers now offer fluorine-free certified alternatives, making them more transparent choices if PFAS avoidance is your priority. Arc'teryx positions itself on durability and fit rather than chemical safety, which is reflective of premium outdoor wear positioning but leaves informed buyers without clear data.
If you buy it
Wash the pants in cool water with mild detergent; avoid dry cleaning or heat, as these can accelerate water-repellent coating breakdown and potentially mobilize any residual finish chemicals. Re-apply water-repellent coating treatment every 2-3 years or when water no longer beads on the surface, using a fluorine-free product if possible to limit cumulative PFAS exposure. Inspect seams and zippers regularly for wear, as degradation does not pose immediate risk but signals the garment's protective capacity is declining. Store in a cool, dry place away from direct sunlight to extend the lifespan of both the nylon and its finish.
