Traditional PTFE (Teflon) and ePTFE membranes, while highly effective, are categorized as PFAS chemicals. The iS MORE® Membrane achieves comparable or superior waterproofing and breathability scores but does so using a hydrophilic, non-PTFE polymer system. The key difference is the environmental impact: the iS MORE® Membrane offers a clean chemistry platform, solving the industry’s biggest sustainability challenge without compromising the technical demands of High-Performance Fabrics. It is a cleaner, greener path for Outdoor Apparel.
