Where these two actually differ

  • We flag Azo dyes and heavy metal pigments, Antimony in polyester and Microplastic shedding on the Arc'teryx and not on the Arc'teryx.
  • We flag DWR coating leaching during use and laundering on the Arc'teryx and not on the Arc'teryx.
  • The Arc'teryx is 100% polyester knit, no water-repellent treatment where the Arc'teryx is Nylon blend with DWR finish, 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 Arc'teryx is the one to buy.

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 →
