Rab Men's Khroma Converge Jacket
Outdoor jacket with water-repellent coating or PFAS risk present but unconfirmed or Rab lacks treatment disclosure.
This jacket features a water-repellent coating finish common in technical outerwear, but Rab doesn't disclose whether it contains PFAS or PFAS-free alternatives. Without third-party testing, assume traditional formulations.

What Rab Men's Khroma Converge Jacket is made of, ingredients and materials
The Khroma Converge is nylon (polyamide) with a water-repellent coating (water-repellent coating) finish applied to the outer surface. water-repellent coating treatments historically rely on fluorinated compounds (PFAS) to achieve water-shedding properties, though some manufacturers have begun transitioning to fluorine-free alternatives. Rab does not publicly disclose whether this jacket uses PFAS-based or alternative water-repellent coating chemistry. Nylon itself is stable and non-toxic when intact; the coating is the primary concern.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
water-repellent coating degradation and leaching
Nylon water-repellent coating finishes degrade with washing and weathering. If PFAS-based (unconfirmed for this model), repeated water exposure and laundering could gradually release fluorinated compounds into wash water and the environment. No data exists on leaching rates specific to Rab Khroma jackets.
Polyamide (nylon) thermal instability
Nylon can degrade at high temperatures (above 140C / 285F). Machine-drying on high heat or exposing the jacket to direct flame could cause polymer breakdown and potentially release volatile compounds. This is a care hazard, not an inherent material risk under normal use.
What’s reassuring
Formaldehyde / VOCs
Nylon fabrics are sometimes treated with formaldehyde-releasing resins for wrinkle resistance or durability. Rab does not advertise such treatments for this jacket, and modern outdoor brands typically avoid them; no recalls or complaints on record for this product.
Source, ATSDR ↗Azo dyes in fabric coloring
The Khroma Converge is available in solid colors typical of outdoor jackets. No public evidence of restricted azo dyes in Rab products, and the brand does not have a history of dye-related safety violations.
Lining material off-gassing
Rab does not disclose lining composition (typically polyester or nylon mesh). No documented off-gassing issues or VOC complaints for this brand in available records.
The full breakdown
The brand's record and disclosure
Rab is a UK-based outdoor brand with a reputation for durability-focused design but has not published a statement on PFAS use or phase-out timelines comparable to major competitors like Patagonia or Arc'teryx. The company does not list water-repellent coating treatment details on product labels or websites. No recalls or documented safety violations are on record for this model. Without public commitment to PFAS-free treatments, consumers cannot verify the chemical composition of the water-repellent layer.
How it compares in its category
Most ski jackets in this price and performance range use water-repellent coating coatings that carry similar PFAS uncertainty unless the brand explicitly certifies fluorine-free treatment. Rab's silence on this issue is typical of mid-market outdoor brands; premium brands like Patagonia and Arc'teryx have begun phasing out PFAS, while budget alternatives may use older, more persistent PFAS chemistry. The Khroma Converge occupies the middle ground, likely functional and durable, but without the transparency of leaders or the cost advantage of non-disclosing competitors.
If you buy it
Wash infrequently in cool water with detergent formulated for technical fabrics; hot water or heat-drying can degrade the water-repellent coating finish and theoretically increase any coating leaching. Do not machine-dry at high heat. Reapply water-repellent coating treatment after 2-3 seasons or when water no longer beads on the surface; use a PFAS-free alternative product if available. Store in a dry location to prevent mold growth inside the lining. If you are sensitive to PFAS exposure or concerned about environmental release, contact Rab directly for treatment chemistry before purchase or consider brands with published PFAS-free certifications.
