Where these two actually differ
- We flag Plastic lid and valve wear/leaching and Bacterial or mold growth in valve mechanism 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 exterior, plastic interior lid/valve where the Yeti is 18/8 stainless steel, no coating, which is most of the difference in these two grades.
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 →
