Where these two actually differ
- We flag PFAS in DWR coating (fluorinated water repellent), Azo dyes in leather or nylon, Formaldehyde in leather finishing or adhesives and Heavy metals in leather dyes or chrome tanning agents on the Asolo and not on the Mephisto.
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the Asolo.
- The Asolo is Leather, nylon, Gore-Tex membrane (unspecified DWR treatment) where the Mephisto is leather, textile, rubber sole, 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 Mephisto is the one to buy.
