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.
