Where these two actually differ
- We flag Antimony in polyester and Microfiber shedding and textile degradation on the La Sportiva and not on the Spiewak.
- We flag Formaldehyde resins in finishes and Coating degradation and microrelease on the Spiewak and not on the La Sportiva.
- The La Sportiva is GORE-TEX (fluoropolymer membrane) where the Spiewak is nylon or polyester with DWR finish, 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, 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 →
