Where these two actually differ

  • We flag Powder-coat finish degradation on the Klean Kanteen and not on the Klean Kanteen.
  • We flag Cap or closure contamination and Bacterial or mold growth from moisture retention on the Klean Kanteen and not on the Klean Kanteen.
  • The Klean Kanteen is stainless steel bottle with powder-coat finish where the Klean Kanteen is 18/8 stainless steel, no interior 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 →
