Global textile specialist eVent Fabrics®, a provider of high-performance all-weather technologies, has launched alpineST, a groundbreaking new PFAS-free laminate solution for highly waterproof and breathable apparel.
With more than twenty-five years of experience developing high-performance waterproofing technologies, eVent Fabrics has now created a sustainable alternative to ePTFE. The innovative alpineST laminate collection is specifically designed for use in extreme conditions, such as high alpine environments, moto, or sailing in stormy weather. It consists of a polyolefin-based membrane combined with recycled fabrics. The C0-DWR coating completely dispenses with fluorine chemistry, without compromising the product’s long-term performance during the utilisation phase. This means that it retains its high waterproofness even after numerous washes. Tests show that the initial waterproofness of 25K still has a water column of 20K even after dozens of washes. With alpineST, eVent presents an innovative technology that combines maximum functionality and durability with a sustainable approach, and which stands out from other PFAS-free offerings on the market.
“Finding a reliable and durable waterproof technology has become a challenge for the industry as it moves away from PTFE to other materials,” said Chad Kelly, President of eVent. “We believe we have developed one of the first PFAS-free alternatives on par with long-lasting, high-quality PTFE.”
Two PFAS-free laminate technologies: eVEnt alpineST and eVent BIO
alpineST is eVent’s second PFAS-free laminate solution. In 2021, the company introduced eVent BIO, a sustainable plant and biomass-based waterproof technology for apparel, footwear and accessories. At the laminate technology’s core are highly renewable plant-based and biomass elements paired with smartly sourced or recycled face and backer fabrics finished with a high-performing CO DWR. The water- and windproof recyclable eVent BIO membrane has a reduced carbon footprint and is lightweight, tough, and flexible.
With its two laminate technologies, eVent alpineST and eVent BIO, the technology provider is paving the way for durable, highly functional apparel, footwear and accessories in a PFAS-free future. Both laminates are fluorine free and comply with European Union regulations as well as a growing number of US states requiring the elimination of PFAS chemicals from many consumer products. The first eVent alpineST products will be available at retail in 2025. eVent® Fabrics, founded in 1999, revolutionized the industry with the first air-permeable 100% waterproof membrane and continues to innovate with sustainable, high-performance textiles. Globally recognized for its breathable waterproof solutions and commitment to eco-friendly materials, eVent® Fabrics empowers adventurers and brands alike to defy the elements. Trusted by leading brands, eVent® Fabrics sets the standard for performance and sustainability in outerwear, footwear, and accessories.
