Where these two actually differ
- We flag Gasket and seal degradation, Bacterial growth in inaccessible spaces and Thermal stress and seal failure 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, no reported coating where the Yeti is 18/8 stainless steel, no coating, which is most of the difference in these two grades.
- These two are 5 points apart, close enough that price and fit should decide it rather than our grade.
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 →
