@Joe Thanks for your patience as we connected with our sustainability team. We heard back from them today and here's what they had to say:
While the industry is working to transition away from the use of PFAS in manufacturing water-repellent apparel, most brands still use short-chain PFAS-based chemistry due to its performance and durability. As noted previously, REI’s Co-op Brands has moved away from the use of long-chain PFAS for the DWR treatments used on our products. In addition, we’re a committed bluesign® System Partner and use bluesign®-approved materials for the majority of our apparel fabrics, including the recycled ripstop nylon shell used in the REI Co-op Rainier Rain Jacket we currently have in-store. Bluesign® is a group that works with brands and factories to certify the chemical inputs, materials, and suppliers that create certified products. The Bluesign® system focuses on consumer safety, resource use, occupational health and safety for workers, and water and air emissions. You can learn more about Bluesign® in REI’s Expert Advice article on the topic.
If you’re looking for PFAS-free rain jackets, there are a handful of options currently at REI, including the North Face FUTURELIGHT series (available here) and the Marmot PreCip Eco Jacket (available here). PFAS-free options will likely become more common in the future as brands continue to innovate and develop additional PFAS-free durable water-repellent technologies that perform as well as those that use PFAS.
Hope this helps!
