Castelli Ultra Rain Cape Men's
Skip until Castelli discloses waterproof finish chemistry.
Castelli's Ultra Rain Cape uses a waterproof treatment on polyester but does not disclose whether it contains PFAS. Without lab data or brand transparency, PFAS risk remains uncertain.

What Castelli Ultra Rain Cape Men's is made of, ingredients and materials
The Castelli Ultra Rain Cape is polyester with an unspecified waterproof treatment. Polyester itself is stable, but the finish applied to achieve water repellency is the critical unknown. Most polyester rain garments use either fluorinated compounds (PFAS family, persistent and bioaccumulative) or, less commonly, polyurethane or wax-based systems. Castelli has not disclosed which chemistry is in this cape, making chemical risk assessment incomplete.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
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 finish chemistry (unspecified)
Castelli does not publicly disclose whether the water-repellent coating treatment is PFAS-based, polyurethane, or another system. Industry data shows >70% of polyester rain gear still uses fluorinated compounds. Without documentation, risk cannot be ruled out.
Formaldehyde / VOCs
Polyester textiles commonly use formaldehyde-releasing resins for wrinkle resistance and dye fixation. Castelli does not specify whether resin-based finishing is applied to this cape. Typical levels in finished garments are low, but not independently verified for this product.
Source, ATSDR ↗Heavy metals
The cape's color is achieved via dyeing. Castelli does not publish dye chemistry or testing against restricted azo compound lists (ZDHC or equivalent). Polyester capes in dark or saturated colors carry higher theoretical risk, though skin contact exposure is limited by garment wear duration.
Source, FDA ↗Microplastics
Polyester-based waterproof finishes, particularly those using Teflon-type coating or polyurethane, shed microfibers and coating particles with repeated washing and wear. This is an established concern for all synthetic rain garments; Castelli products are not exempt. Washing releases both fibers and coating fragments into wastewater.
Source, EPA ↗Lack of safety transparency and third-party certification
Castelli makes no claim to OEKO-TEX, ZDHC, or other chemical safety certifications for this cape. The absence of third-party vetting or brand disclosure of restricted substances is the primary evidence marker for skip recommendation.
The full breakdown
The brand's record and disclosure
Castelli (owned by Telekom Italia subsidiary and distributed globally) does not publish waterproof finish chemistry on product spec sheets or in response to queries reviewed in public consumer forums. The brand has no widely documented PFAS commitment or phase-out timeline. This silence is notable in a category where competing brands (e.g., Patagonia, Gore) increasingly disclose or eliminate PFAS from rain garments. No major safety recalls or formaldehyde violations are on record for Castelli rain wear, but opacity on finishes remains a concern.
How it compares in its category
Many cycling rain capes and jackets still rely on PFAS-based durable water repellency (water-repellent coating) finishes because they are durable and cost-effective. However, alternatives using fluorine-free polyurethane coatings or paraffin blends exist from other manufacturers. Castelli's failure to specify treatment chemistry places it below brands that voluntarily disclose or have committed to PFAS reduction, even if the actual finish is borderline.
If you buy it
Machine wash in cool water with minimal agitation; heat accelerates coating breakdown and may volatilize residual finish chemicals. Air dry; tumble drying is not recommended. Do not iron. Expect the waterproof layer to degrade after 50-100 washes depending on water hardness and detergent type. If you choose this cape, contact Castelli's customer service directly to request written confirmation of the waterproof treatment chemistry before purchase; silence may shift your decision.
