Where these two actually differ
- We flag Nickel leaching from stainless steel, Surface corrosion and pitting over time and Bacterial growth in cap seals on the Klean Kanteen and not on the Owala.
- We flag Seal and gasket degradation, Stainless steel corrosion (rare) and Bacterial growth in standing water on the Owala and not on the Klean Kanteen.
- The Klean Kanteen is 18/8 stainless steel, no interior coating where the Owala is Stainless steel, no reported coating, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
