Lowe Alpine have been carefully monitoring the emerging environmental concerns about PFCs and working hard on this issue behind the scenes. PFCs (Perfluorocarbons) are compounds that are widely used in many different industries, including the manufacture of durable water repellent finishes (DWRs) commonly used on backpack fabrics. At Lowe Alpine environmental responsibilities have always been taken very seriously and they are working proactively to manage PFCs responsibly with the information available. They have now committed to a goal of switching from PFC-based technologies for all their products by 2020. More information on the Lowe Alpine website.
