What Marmot says and does about PFAS
Marmot describes some of its rain gear as PFC-free, a term the outdoor industry has long used for fluorinated water repellents, rather than as PFAS-free. Its PreCip Eco rain jacket uses a face fabric Marmot calls PFC-free, and in 2021 the Sierra Club reported that Marmot had a growing collection of PFAS-free clothing and was working to become completely free of PFAS. We found no Marmot statement that its whole range is PFAS-free, so check the grade of the exact product.
