What is this product?
Outdoor gear and apparel represent a significant consumer PFAS exposure pathway through PTFE-based waterproof breathable membranes (Gore-Tex and similar technologies) and durable water repellent (DWR) finishes applied to shells, pants, gloves, backpacks, tents, and footwear. The outdoor industry has historically relied on fluorotelomer-based DWR chemistry — initially C8 (perfluorooctane-based) and transitioning to C6 (perfluorohexane-based) after 2015 — to achieve durable water and oil repellency that withstands repeated laundering and field use. A garment treated with fluorinated DWR typically contains 1-5 grams of fluorinated chemistry per square meter of fabric. During wear, PFAS volatilize and shed from treated textiles — a 2022 study in Environmental Science & Technology measured elevated PFAS levels in indoor air and dust of outdoor gear retail stores compared to other retail environments. Laundry of treated garments releases PFAS to wastewater: Lassen et al. (2015, Danish EPA) found measurable PFAS in laundry effluent from fluorinated textile washing. Ski wax containing fluorocarbons was banned in competitive skiing by the International Ski Federation (FIS) effective 2023 season, driven by both environmental and athlete health concerns — ski technicians showed elevated blood PFAS levels correlated with wax application exposure. The EU's comprehensive PFAS restriction proposal under REACH, submitted by five national authorities in 2023, would ban all PFAS in textiles with a transition period — this would effectively eliminate fluorinated DWR from the European market. Non-fluorinated DWR alternatives have improved significantly: silicone-based treatments (Nikwax), wax-based finishes, dendrimer technologies, and bio-based repellents now achieve 80-90% of the water repellency performance of fluorinated treatments, though oil repellency and durability after 50+ wash cycles remain inferior. Patagonia committed to eliminate all PFAS from its product line by 2025, with most product categories already transitioned. Arc'teryx, The North Face, and other major brands have announced similar timelines.
