27oz Wide Water Bottle with Loop Cap vs Stainless Steel Vacuum Insulated Wide Mouth Water Bottle Thermos Keeps Cold for 24 hours: which is safer?

Where these two actually differ

• We flag Cap or closure contamination and Bacterial or mold growth from moisture retention on the Klean Kanteen and not on the Mira.
• We flag Seal and gasket degradation (bacterial growth risk), Cap and closure material leaching and Vacuum seal compromise over time on the Mira and not on the Klean Kanteen.
• The Klean Kanteen is 18/8 stainless steel, no interior coating where the Mira is Stainless steel body, interior vacuum insulation, which is most of the difference in these two grades.
• The gap is 30 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
