Where these two actually differ
- We flag PFAS in water-resistant coating (DWR), Azo dyes in polyester/nylon, Antimony catalyst residue in polyester and Microfiber shedding from coating wear on the Decathlon and not on the Granite Gear.
- We flag Heavy metals in zippers or hardware on the Granite Gear and not on the Decathlon.
- The Decathlon is Polyester/nylon with water-resistant coating 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.
- We are less certain about the Decathlon grade, at 42% 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 →
