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 Salomon.
  • We flag DWR coating degradation and re-exposure, Polyester fiber microplastic shedding, Adhesive and solvent off-gassing from glued seams and Undisclosed PFAS in DWR finish (pending separate grade) on the Salomon and not on the La Sportiva.
  • The La Sportiva is synthetic textile with Gore-Tex membrane waterproof layer where the Salomon is Polyester with waterproof DWR coating (unspecified chemistry), 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 →
