Where these two actually differ
- We flag Azo dyes and heavy metal pigments and Antimony in polyester on the Arc'teryx and not on the HOKA.
- We flag PFAS in DWR treatment on the HOKA and not on the Arc'teryx.
- Both carry a flag for Microplastic shedding, so neither choice avoids it.
- The Arc'teryx is 100% polyester knit, no water-repellent treatment where the HOKA is Nylon blend with durable water repellent (DWR) treatment, 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.
- We are less certain about the HOKA grade, at 35% confidence against 72%, because it discloses less.
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 →
