Specialized Men's RBX Comp Rain Jacket
Skip until Specialized discloses water-repellent coating chemistry.
Rain jacket uses standard water-repellent coating water-repellent treatment, typically PFAS-based. Specialized provides no public disclosure of coating composition or PFAS status.

What Specialized Men's RBX Comp Rain Jacket is made of, ingredients and materials
The RBX Comp is polyester base fabric with a water-repellent coating (water-repellent coating) finish applied to the surface. Polyester itself is stable and does not readily leach chemicals under normal wear conditions. However, the water-repellent coating is the chemical wildcard, traditional fluorocarbon-based repellents (C8, C6, or legacy PFOA) persist in the environment and body; newer alternatives like silicone or wax-based systems pose much lower concern but Specialized has not publicly specified which is used here.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.

No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Polyester rain jackets commonly use C6 or legacy fluorocarbon water-repellent coating finishes; Specialized has not disclosed the specific chemistry for this model, making it reasonable to assume a fluorinated product unless stated otherwise. User exposure is primarily dermal and inhalation during use and washing.
Source, ATSDR ↗Azo dyes in polyester
Polyester apparel frequently uses azo dyes for coloring. While most azo dyes sold in developed markets meet regulatory restrictions, some can break down into carcinogenic aromatic amines under specific conditions (acidic sweat, heat, microbial degradation). No Specialized disclosure or third-party testing result on record for this jacket rules out the hazard.
Antimony catalyst residues in polyester
Polyester is synthesized using antimony trioxide as a catalyst; residual antimony can remain in the finished fiber at trace levels (typically <100 ppm). Migration into sweat under warm conditions is not well-studied for apparel, but antimony is a known skin and respiratory irritant at higher concentrations. Washing and normal wear are unlikely to pose acute risk, but prolonged intimate contact (e.
Formaldehyde / VOCs
Water-repellent coating and other textile finishes sometimes incorporate formaldehyde-based crosslinkers to improve durability. Specialized does not advertise formaldehyde-free finishes for this model. New garments may off-gas low levels; washing reduces this significantly. Risk is low for occasional outdoor use but not negligible for daily wear or in unventilated spaces.
Source, ATSDR ↗Volatile organic compounds (VOC) from finish off-gassing
Polyester fabrics with water-repellent coating and other chemical coatings can emit low-level VOCs (styrene, aromatic hydrocarbons) especially when new or when stored in warm, enclosed spaces. Risk is reduced by washing before first wear and air-drying. Outdoor use poses minimal inhalation risk; indoor storage in poorly ventilated areas is the higher-concern scenario.
How is this PFAS grade calculated?
The brand's record and disclosure
Specialized has not issued public statements on water-repellent coating chemistry or PFAS phase-out commitments for apparel. No independent certifications (Bluesign, GOTS, OEKO-TEX) are advertised for this model, which would otherwise provide third-party verification of restricted chemicals. The brand's silence on this standard disclosure point in outdoor apparel is a red flag relative to competitors like Patagonia, Arc'teryx, and even budget brands that now routinely disclose or eliminate fluorinated water-repellent coating.
How it compares in its category
Men's rain jackets commonly use fluorinated or non-fluorinated water-repellent coating finishes. Premium brands increasingly advertise PFAS-free alternatives (wax, silicone, or newer fluorine-free polymers); budget and mid-tier brands remain mixed. Specialized's RBX line targets mid-market cyclists and does not distinguish itself on chemical transparency, placing it in the less-cautious segment of the category. Direct competitors offering comparable water resistance with disclosed PFAS-free coatings exist at similar price points.
If you buy it
Wash separately in cool water before first wear to remove loose surface finishes and residual manufacturing chemicals. Avoid machine drying on heat; air dry only, as heat can accelerate any volatile off-gassing from the water-repellent coating layer. Replace the jacket if the water-repellent function degrades noticeably (water beading stops), as re-treating at home with unknown products may compound exposure. Limit direct skin contact with the inner surface if possible, and do not use for children's clothing given uncertainty about water-repellent coating chemistry and smaller body burden.
