Where these two actually differ
- We flag Nickel leaching from stainless steel and Surface corrosion and pitting over time on the Klean Kanteen and not on the Klean Kanteen.
- Both carry a flag for Bacterial growth in cap seals, so neither choice avoids it.
- The Klean Kanteen is 18/8 stainless steel, no interior coating where the Klean Kanteen is Stainless steel bottle, bamboo cap, 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 →
