Where these two actually differ
- We flag PFAS in DWR coating on the Marmot and not on the REI Co-op.
- We flag UV degradation and additive leaching, Microplastics from mechanical wear and Odor and volatile organic compounds from manufacturing on the REI Co-op and not on the Marmot.
- The Marmot is Nylon, polyester, DWR coating (type unspecified) where the REI Co-op is Polypropylene storage bin, no water-resistant coating mentioned, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the REI Co-op is the one to buy.
- We are less certain about the Marmot grade, at 35% confidence against 78%, because it discloses less.
