Endura Hummvee Waterproof Jacket Men's
Skip until Endura discloses water-repellent coating chemistry or certifies PFAS-free.
Endura Hummvee uses unspecified water-repellent coating on polyester. Brand provides no PFAS disclosure, making risk assessment impossible for waterproof jackets typically treated with fluorochemicals.

What Endura Hummvee Waterproof Jacket Men's is made of, ingredients and materials
The Hummvee uses polyester with an unspecified water-repellent coating (water-repellent coating) coating. water-repellent coating coatings historically relied on PFAS chemistry, though some brands have switched to non-fluorinated alternatives; Endura has not disclosed which type is used here. Polyester itself is inert when unworn, but the coating's chemical identity determines potential leaching or off-gassing exposure, especially during washing or heat exposure.
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.
PFAS
Endura does not disclose whether the water-repellent coating is fluorinated (PFAS-based) or fluorine-free. Fluorinated water-repellent coating coatings are known to release PFAS during wear and washing; fluorine-free alternatives carry lower risk but are not confirmed here.
Source, ATSDR ↗Coating microparticle shedding upon degradation
As water-repellent coating coatings age and delaminate, small particles may shed into washing water or air. The hazard level of these particles depends on the coating composition, which is undisclosed.
Microplastics
Polyester jackets shed microfibers, especially during washing. This is not unique to Endura but is a known concern with all synthetic cycling wear; shedding increases with mechanical wear and laundering.
Source, EPA ↗Heat sensitivity of water-repellent coating
High-temperature drying or direct heat exposure can degrade water-repellent coating coatings prematurely, potentially releasing coating particles or reducing water repellency. Care instructions are critical.
What’s reassuring
Formaldehyde / VOCs
No reports of formaldehyde-based resins in the Hummvee. Polyester rain jackets typically avoid formaldehyde finishes, but absence of certification means this cannot be ruled out without testing.
Source, ATSDR ↗The full breakdown
The brand's record and disclosure
Endura has published no public PFAS policy, material transparency documents, or third-party certifications (BLUESIGN, OEKO-TEX, GOTS) that would indicate water-repellent coating chemistry. The brand's silence on a widely-known industry debate about fluorinated water repellents suggests either use of legacy PFAS-based water-repellent coating or lack of priority on disclosure. No major recalls or controversies specific to the Hummvee are on record.
How it compares in its category
Many premium cycling rain jackets now advertise PFAS-free water-repellent coating (e.g., Patagonia, Rab, some Arc'teryx lines) or carry third-party certifications. The Hummvee's lack of disclosure places it below these leaders in the transparency ranking, though its price point and durability reputation remain competitive for riders unconcerned with PFAS exposure. Budget alternatives often omit water-repellent coating entirely or use untested coatings.
If you buy it
Wash by hand or gentle machine cycle with minimal detergent to preserve the water-repellent coating and reduce any coating particulate release. Avoid high heat drying; air dry or low heat to prevent polymer degradation. Replace the jacket if the coating visibly delaminates, becomes chalky, or loses water beading, as a failing coating may shed microparticles. Store in a cool, dry place away from direct sunlight to extend coating life.
