Where these two actually differ
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the The North Face.
- We flag PFAS in DWR coating, Antimony in polyester textile upper and Microorganism growth in moisture-prone seams on the The North Face and not on the Mephisto.
- The Mephisto is leather, textile, rubber sole where the The North Face is Gore-Tex membrane with textile upper and synthetic/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.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
