Where these two actually differ
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the Scarpa.
- We flag Formaldehyde resins in textile finishing and Microplastic shedding from laminate degradation on the Scarpa and not on the Mephisto.
- The Mephisto is leather, textile, rubber sole where the Scarpa is Gore-Tex membrane, synthetic upper and lining, 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.
