    Gorpcore was once a niche subculture for climbers, hikers and weekend campers, but has since become one of fashion\u2019s most influential aesthetics. Even though it\u2019s designed for extreme weather conditions, technical shells are being styled with Prada loafers and waterproof pants appear as often in London caf\u00e9s as they do on mountain trails. But as luxury fashion moves into gorpcore, and high-performance materials migrate into everyday wardrobes, the risks associated with gorpcore\u2019s performance-enhancing chemicals do, too.<\/p>\n

    At the center of this are PFAS \u2014 or perfluoroalkyl and polyfluoroalkyl substances \u2014 a vast family of synthetic chemicals prized for its ability to repel water, stains and oil. In outdoor apparel, they\u2019re everywhere: in waterproof coatings, stain-resistant finishes, odor-control treatments and even some membranes. They\u2019re the reason a jacket keeps you dry in a storm or a pair of pants withstands abrasive wear. But they\u2019re also persistent and increasingly linked to a long list of environmental and health risks.<\/p>\n

    \u201cPFAS have really been one of the most pressing issues in the past decade. Commonly known as \u2018forever chemicals\u2019 […] what makes PFAS a real problem is their persistence and mobility,\u201d says Dr. Daniel Waterkamp of Bluesign, an organization and certifying body that supports brands, manufacturers and chemical suppliers with safe chemical management. \u201cPFAS have spread around the world and can even be found in the Arctic. Some substances in the PFAS family are proven to bioaccumulate [meaning they build up in the body over time] and to be carcinogenic and toxic to reproduction.\u201d<\/p>\n

    Despite rising awareness, PFAS have remained deeply embedded in the outdoor sector because the technical supply chain is specialized, global and slow to shift. \u201cPhasing things out can take time. It took us a decade to get our entire line free of intentionally added PFAS because we did not want to sacrifice quality,\u201d says Matt Dwyer, VP of product footprint at Patagonia. The brand uses the phrase \u201cintentionally added PFAS\u201d to distinguish between chemicals purposefully used in production and the trace contamination that can appear unintentionally. Patagonia also worked with waterproof membrane supplier Gore-Tex to develop a new PFAS-free material called expanded polyethylene (ePE), which is a safer, non-toxic alternative, Dwyer adds. \u201c[That] helps the entire industry move forward.\u201d<\/p>\n

    Systemic change is possible, but far from complete, adds Rebecca Fuoco, director of science communications at the Green Science Policy Institute. \u201cA big piece of the problem is supply chain complexity. Textile mills, finishers, laminators and membrane suppliers have long experience with fluorinated products. Switching requires retooling, new process controls, testing protocols and new supplier relationships,\u201d she explains. Still, several brands have proven the transition is practically and economically feasible. \u201c[Footwear brand] Keen and [sportswear brand] Houdini have been PFAS-free for years; and as of spring 2025, all Patagonia products are made without intentionally added PFAS.\u201d<\/p>\n

    A toxic performance<\/strong><\/h2>\n

    The health implications of PFAS are well documented. \u201cPFAS exposure is linked to thyroid dysfunction, liver and kidney damage, suppressed immune response, hormonal disruption, developmental delays in children and several cancers,\u201d says Fuoco. While consumers can absorb a very small amount of PFAS directly through wearing clothing in contact with skin, PFAS also shed, meaning they are in the household dust that we breathe and ingest. \u201cThis contributes to cumulative body burden over time,\u201d she adds, noting that the textile workers making gorpcore garments tend to experience PFAS body burdens five to 10 times higher than the general population, with significantly increased risks of liver disease and cancer.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    But PFAS are only the starting point. Performance apparel often relies on chemical systems for functions far beyond waterproofing, including stain repellents, wicking agents, flame retardants, anti-pilling coatings, anti-fungal treatments and solvent-heavy laminates.<\/p>\n

    Odor-control finishes are a prime example, frequently touted as a benefit of gorpcore clothes. These antimicrobial treatments are marketed as maintaining freshness, but experts note that while some formulations work under certain conditions, many others show limited or inconsistent efficacy. \u201cIn backcountry or high-sweat technical use, antimicrobial coatings are sometimes added with the intention of slowing odor build-up,\u201d Fuoco explains. Some \u201crelease metals and biocides into wastewater and expose workers to chemicals linked to skin and breathing problems, reproductive harms, microbiome disruption and more\u201d, she adds.<\/p>\n

    Beyond the wearer, these chemicals move through the garment\u2019s entire lifecycle, released during production, washing and disposal. Wastewater treatment plants cannot fully filter PFAS or many antimicrobial agents, meaning they accumulate in rivers, soil, agricultural systems and even drinking water. Once released, many persist for decades. And then there\u2019s abrasion. Everyday use \u2014 backpacks rubbing against jackets, sleeves brushing caf\u00e9 tables, pants scraping along bike saddles \u2014 erodes technical coatings and sheds microplastics and chemical-laced dust into the environment. High-performance fabrics, designed to last through storms, paradoxically shed more when worn casually and washed frequently in everyday life.<\/p>\n

    A path forward<\/strong><\/h2>\n

    Some brands are demonstrating what high performance without PFAS can look like.<\/p>\n

    P\u00e1ramo, long considered an outlier in the outdoor sector, has built its waterproofing system around a PFAS-free approach from the start. Its Analogy waterproofing system, developed in collaboration with PFAS-free waterproofing specialist Nikwax, \u201cprovides ultra-breathable performance without laminates, membranes or taped seams\u201d, says Samantha Theron, P\u00e1ramo\u2019s head of marketing and communications.<\/p>\n

    The system uses a two-layer construction. The first layer is an outer, closely woven synthetic microfiber \u2014\u00a0typically nylon or polyester \u2014\u00a0finished with a durable, water-repellent (DWR) finish. This DWR is a water-based, non-fluorinated (meaning it contains no PFAS, or other \u201cforever chemicals\u201d) polymer designed to bond to the fibers and help the surface shed rain. Then, there\u2019s an inner \u201cpump liner\u201d, also made from synthetic fibers, designed to transport liquid water (sweat or condensation) outward, mimicking how fur works in wet conditions.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    Crucially, because there is no bonded membrane or taped seams, there are fewer failure points and the waterproofing can be renewed indefinitely with Nikwax\u2019s water-based aftercare products. Still, the approach has its own trade-offs. Garments are typically heavier and warmer than membrane-based shells, and like all synthetics, they can still shed microfibers during washing, illustrating that PFAS-free does not automatically mean impact-free.<\/p>\n

    P\u00e1ramo also emphasizes maintenance as a sustainability tool. \u201cThe most sustainable outdoor choice isn\u2019t replacing your gear, it\u2019s maintaining it,\u201d notes Theron. Proper cleaning and reproofing can dramatically extend the life of technical garments, and while PFAS-free coatings sometimes require more frequent upkeep, performance can be quickly restored with Nikwax aftercare. The brand says many of its original jackets are still used daily and perform well after 15 years or more.<\/p>\n

    P\u00e1ramo has a fabric-testing protocol, which it says guarantees total exclusion of PFAS across all products and processes.<\/p>\n

    Durability is also a cornerstone of Patagonia\u2019s transition away from PFAS. \u201cAs we were introducing non-PFAS-based DWR for technical use, we had to go through hundreds of combinations of fabrics and treatments to find things that worked and fit within our environmental responsibility requirements,\u201d says Dwyer. \u201cNot every waterproofing worked with every material, so we had to systematically work through the combinations to find what worked best.\u201d In practice, the team found that some early PFAS-free chemistries simply didn\u2019t hold up. Certain coatings caused fabrics to feel stiff or noisy, others reduced breathability, while some \u201cwet out\u201d (meaning the outer fabric starts to absorb water instead of repelling it) far faster than the fluorinated versions they were meant to replace. In a few cases, the alternatives compromised abrasion resistance or tear strength, which meant Patagonia had to either rethink the fabric construction or limit where a given treatment could be used. Those setbacks, Dwyer notes, were part of the learning curve \u2014 a reminder that moving away from PFAS often means compromising between performance, durability and environmental impact, rather than finding a single substitute that works everywhere.<\/p>\n

    Patagonia\u2019s approach also required rethinking where PFAS and related chemistries were being used unnecessarily. \u201cWe started looking at all applications of the chemistries across our product line and started either replacing them in non-critical applications with suitable substitutes, or just stopping use altogether in some cases,\u201d Dwyer adds. For example, in its Black Hole bags \u2014 Patagonia\u2019s durable travel and outdoor duffles and backpacks known for their weather-resistant design and TPU-laminated fabric \u2014\u00a0the inner lining once used PFAS-based treatments even though the bags are geared for transport rather than extreme waterproofing. By removing the PFAS-treated lining, Patagonia eliminated a non-critical PFAS use case. The brand\u2019s final step, transitioning its fly-fishing waders, is complete as of spring 2025, marking the end of a decade-long shift.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    The company is also experimenting with end-of-life solutions, which is still a major gap in technical apparel. For example, Patagonia\u2019s Nano Puff program collects irreparable items and sends them to a specialized recycler in Texas founded by material innovation company Eastman, where the brand says they are processed into new fiber, signaling the future direction of circularity for performance gear. In 2024, Patagonia says it shipped around 8,000 pounds of unusable apparel into this system \u2014 a promising proof of concept, but still tiny compared with global textile waste, and the process comes with big caveats:Eastman only accepts feedstock that\u2019s pure polyester and \u201cclean\u201d of zips, buttons and other non-fabric components, meaning each piece has to be carefully sorted and stripped before it can be recycled. Those constraints help explain why textile-to-textile schemes remain experimental rather than truly scalable, even as they hint at a more circular future for performance gear.<\/p>\n

    Patagonia also focuses on circularity by expanding repair and product care guidance through its Worn Wear program. Last year, the program repaired more than 170,000 products globally. \u201cThe most responsible product is the one you already own,\u201d says Dwyer. \u201cAcross the company, we constantly question whether responsible growth is possible without compromising our values. That means asking questions such as: does this product need to exist? Can it be repaired? Will it last? And can we reduce the impact of making it?\u201d<\/p>\n

    As PFAS-free claims become more visible, experts caution that simplistic marketing can obscure a more nuanced reality. Labels such as \u201cPFAS-free\u201d or \u201cchemical safe\u201d imply absolutes that chemistry rarely offers. \u201cThose expressions are misleading,\u201d says Bluesign\u2019s Dr. Waterkamp. To avoid greenwashing, brands should work with partners to \u201ccombine technical know-how with robust digital tools to record, verify and manage impact data\u201d, he adds.<\/p>\n

    It\u2019s a level of scrutiny that some brands have already begun to apply internally. In 2014, with mounting evidence of the harmful, persistent nature of fluorinated chemicals, P\u00e1ramo introduced a fabric-testing protocol, which it says guarantees total exclusion of PFAS across all products and processes. The test, known as combustion ion chromatography, uses high-temperature combustion followed by ion analysis to detect even trace fluorinated substances. Yet, relatively few outdoors brands have adopted it, partly because it can be technically demanding, requires specialist lab equipment and expertise, and is more expensive than simpler spot checks. There are also practical limitations: it is typically used on selected samples rather than every single item, and it can\u2019t (on its own) fix upstream problems in complex global supply chains, so it is far from a total guarantee in practice.<\/p>\n

    The newness issue<\/strong><\/h2>\n

    Behind the chemistry debates sits a more uncomfortable truth: the outdoors industry\u2019s growth model is itself a sustainability problem. As gorpcore continues to push performance gear into everyday fashion, many brands now design for \u201cnewness\u201d rather than longevity, producing more styles, more frequently, for a broader pool of less specialist customers. These garments are often worn daily rather than for occasional outdoors use, meaning they wear out faster \u2014 driving up replacement cycles, and, by extension, the total volume of PFAS-treated products entering the world, whether or not the chemistries are changing.<\/p>\n

    The brands acknowledge the tension. Patagonia\u2019s Dwyer argues that shifting consumer identity is essential: \u201cIf we want people to start seeing themselves as product owners rather than consumers, we as businesses must help explain why that\u2019s necessary and what that means. It means that businesses should be investing in building high-quality products, making them repairable, and researching responsible end-of-life solutions.\u201d This responsibility also extends to education around non-PFAS chemistries, which, he notes, \u201care more susceptible to outside contamination, like oils or sweat\u201d, and therefore require more routine care to maintain performance.<\/p>\n

    For Dwyer, the industry needs to abandon the idea that sustainability can be framed as a selling point at all. \u201cNothing we do is sustainable,\u201d he says. \u201cWe have to move past using environmental responsibility as a marketing claim or a product benefit. Environmental responsibility must become the norm for all companies.\u201d<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n
