Do Marmot waterproof outdoor gear storage bags have PFAS?
Marmot waterproof outdoor gear storage bags average 24 out of 100 on PFAS Authority's PFAS and toxin screen across the 12 Marmot waterproof outdoor gear storage bags graded as of October 2026, above the 20 out of 100 median for the 29 other waterproof outdoor gear storage bags brands graded alongside it.

PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
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.
