What Columbia says and does about PFAS
Columbia Sportswear Company says it completed a PFAS phase-out for all product types and brands at the end of 2024, and its September 2024 position statement described the transition and a possible different deadline for some severe-weather products. A 2022 NRDC, PIRG and Fashion FWD scorecard gave it an F and a petition campaign followed. We found no PFAS lawsuit against Columbia over its products.
