Where these two actually differ
- We flag PFAS in waterproofing treatment (unknown application), Microplastic shedding from EVA degradation, Off-gassing or odor (material volatiles) and Seal degradation and bacterial growth on the Geckobrands and not on the Pela.
- We flag Coating degradation and durability over time and Allergic contact dermatitis from plant fiber or resin on the Pela and not on the Geckobrands.
- The Geckobrands is EVA foam or TPU, seals where the Pela is Flax fiber and plant-based resin blend, compostable, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Pela is the one to buy.
- We are less certain about the Geckobrands grade, at 45% confidence against 92%, 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 →
