Where these two actually differ
- We flag DWR coating composition (PFAS class) - graded separately on the Granite Gear and not on the Granite Gear.
- We flag Heavy metals in zippers or hardware on the Granite Gear and not on the Granite Gear.
- The Granite Gear is Nylon fabric with DWR water-repellent treatment where the Granite Gear is Cordura nylon fabric, 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 Granite Gear is the one to buy.
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 →
