Where these two actually differ

  • We flag Azo dyes, Formaldehyde-releasing resins in finishing and Antimony in polyester on the La Sportiva and not on the The North Face.
  • We flag PFAS in DWR coating, Azo dyes in synthetic uppers, Heavy metals in dyes or pigments and Formaldehyde in waterproof finish on the The North Face and not on the La Sportiva.
  • The La Sportiva is synthetic textile with Gore-Tex membrane waterproof layer where the The North Face is Synthetic uppers with waterproof membrane and DWR-treated fabric, which is most of the difference in these two grades.
  • These two are level, close enough that price and fit should decide it rather than our grade.

Both products run through the same public rubric: 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 →
