Where these two actually differ
- We flag Heavy metals in zippers or hardware on the Granite Gear and not on the Kelty.
- We flag PFAS in DWR coating on the Kelty and not on the Granite Gear.
- The Granite Gear is Cordura nylon fabric where the Kelty is Nylon with DWR water-resistant 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 Granite Gear is the one to buy.
- We are less certain about the Kelty grade, at 45% confidence against 72%, because it discloses less.
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 →
