SCARPA Vento GTX Men's
Gore-Tex likely contains PFAS. Scarpa silent on chemicals.
Vento GTX uses Gore-Tex waterproof membrane, which commonly contains PFAS, though specific formulation unknown. Scarpa makes no PFAS disclosure for this model.

What SCARPA Vento GTX Men's is made of, ingredients and materials
The Vento GTX uses a Gore-Tex membrane laminated to synthetic textile uppers and synthetic lining. Gore-Tex's water-repellency comes from polytetrafluoroethylene (Teflon-type coating) architecture and historically relies on fluorochemical treatments to maintain durability and breathability, which is the documented source of PFAS in this shoe. The synthetic uppers (likely polyester or nylon) themselves do not inherently require PFAS, but the Gore-Tex layer is the critical component here.
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
Synthetic textiles and laminates may undergo formaldehyde-based finishing for wrinkle resistance or durability; Scarpa does not disclose finishing chemistry. Exposure risk in footwear is generally lower than in apparel due to smaller surface area and outdoor ventilation during use.
Source, ATSDR ↗Microplastic shedding from laminate degradation
Gore-Tex membranes and synthetic textiles shed microfibers over time, especially with flexing at seams and abrasion during hiking. This is inherent to the material class, not a Scarpa-specific defect, but intensifies if the laminate delaminates prematurely.
What’s reassuring
Azo dyes in synthetic textiles
Synthetic uppers and linings may use azo dyes, but no specific reports of non-compliant azo dye content exist for Scarpa Vento GTX. Industry standards (REACH, OEKO-TEX) restrict carcinogenic azo compounds; no indication Scarpa violates these.
Antimony in polyester
Polyester in uppers and lining may contain antimony as a catalyst residue. No recalls or reports specific to Scarpa or Gore-Tex boots; industry-wide levels are typically low and not a primary concern in footwear.
Adhesive leachates from Gore-Tex lamination
Polyurethane or other adhesives used to bond Gore-Tex to uppers may leach during moisture exposure. No established reports of skin irritation or chemical leaching from Gore-Tex boots; adhesive systems are generally inert once cured.
The full breakdown
The brand's record and disclosure
Scarpa has not published a public chemical disclosure policy, restricted substance list, or third-party certifications (such as Bluesign or OEKO-TEX) for this model as of available records. The brand does not appear to have made statements on fluorochemical use or phase-out timelines. This silence makes it impossible to know whether Scarpa has negotiated PFAS-reduced Gore-Tex variants or maintains legacy formulations.
How it compares in its category
Hiking boots with Gore-Tex membranes are the industry standard for waterproof/breathable performance; nearly all premium competitors (Salomon, La Sportiva, Danner) use the same membrane technology and face identical PFAS exposure. Non-Gore-Tex alternatives exist (eVent, Membrane) but are less common in this price tier. The real differentiation is brand transparency, some manufacturers now disclose use of Teflon-type coating-free or fluorine-free membranes; Scarpa does not. Brands like Patagonia and some Arc'teryx lines now explicitly phase Gore-Tex in favor of reduced-PFAS laminates, making them outliers, not the norm.
If you buy it
Wash these boots by hand in cool water with mild soap; do not machine wash or use hot water, which can degrade the laminate and increase microfiber shedding. Avoid heat sources and direct sunlight for storage, as UV and heat accelerate polymer breakdown. Re-treat the upper with a silicone-based water repellent (not fluorinated) every 1-2 seasons if the upper loses beading. Replace when Gore-Tex delaminates visibly or breathability noticeably declines, typically 3-5 years of regular use.
