Endura MT500 Waterproof Jacket Men's
Skip until Endura clarifies waterproof coating composition.
Endura MT500 uses a waterproof treatment but does not disclose whether it contains PFAS. Uncoated polyester base is lower concern, but coating source remains unknown.

What Endura MT500 Waterproof Jacket Men's is made of, ingredients and materials
The MT500 is polyester with an unspecified waterproof coating. Polyester itself is stable, but the waterproof treatment is the critical unknown, most outdoor jackets use either PFAS-based (fluorocarbon) coatings or polyurethane or wax-based coatings not linked to PFAS. Endura has not publicly disclosed which technology is in this model. The coating is what creates water resistance but also the primary chemical exposure risk.
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.
Formaldehyde / VOCs
Polyester textiles are often treated with formaldehyde-containing resins for wrinkle resistance and dimensional stability. Endura does not advertise formaldehyde-free processing. The risk is modest with conventional handling but increases with heat exposure or repeated washing in hot water.
Source, ATSDR ↗Heavy metals
The jacket's color is achieved via synthetic dyes; if azo-based and poorly fixed, they can release aromatic amines under sweat or friction. No specific brand certifications (like OEKO-TEX) are noted, so heavy metal content of pigments is unverified.
Source, FDA ↗Waterproof coating volatilization and migration
Polyurethane and fluorocarbon coatings can off-gas volatile organic compounds (VOCs), especially during first wear and in warm conditions. This is distinct from PFAS leaching and typically decreases after initial off-gassing, but intensity depends on coating type and curing, neither disclosed here.
Coating degradation releasing particles
As the waterproof layer wears, micro-flaking of polymer particles can occur, particularly at seams and high-friction areas. Long-term inhalation risk is low, but particles are not biodegradable and represent end-of-life contamination.
The full breakdown
The brand's record and disclosure
Endura is a UK-based cycling apparel brand with no publicly available statements on PFAS elimination, alternatives, or third-party testing transparency. The company does not advertise PFAS-free certifications (such as OEKO-TEX or bluesign) on this product. This silence is a red flag in an industry where transparency on waterproof chemistry is increasingly standard among safety-conscious competitors.
How it compares in its category
Waterproof cycling jackets are among the most chemically intensive garment categories. Competitors like Patagonia, Arc'teryx, and Rab have publicly committed to PFAS elimination or phased removal, with some offering certified PFAS-free lines. Endura's lack of disclosure places it below the transparency standard of premium outdoor brands, though many mid-market jackets remain similarly opaque.
If you buy it
Wash separately from other garments in cool water (do not dry-clean, which can degrade coatings and increase chemical leaching). Avoid machine drying and high heat; air dry to extend coating life. Inspect seams and coating annually for wear; once the waterproof layer degrades, the garment should be replaced rather than re-treated at home. Request product documentation from Endura specifying the coating chemistry before purchase if PFAS exposure is a concern.
