Where these two actually differ
- We flag Interior coating composition (PFAS and non-PFAS fluorinated compounds), Coating degradation and microplastic/particulate release and Off-gassing from coating under heat stress on the Contigo and not on the Yeti.
- We flag Nickel leaching from stainless steel on the Yeti and not on the Contigo.
- The Contigo is stainless steel with unspecified interior coating where the Yeti is 18/8 stainless steel, no coating, which is most of the difference in these two grades.
- The gap is 65 points, wide enough that this is not a close call, and the Yeti is the one to buy.
- We are less certain about the Contigo grade, at 35% confidence against 82%, because it discloses less.
Both products run through the same public rubric: 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 →
