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 LARQ.
- We flag Bacterial growth in filter housing and Seal degradation over time on the LARQ and not on the Klean Kanteen.
- The Klean Kanteen is 18/8 stainless steel, no interior coating where the LARQ is Stainless steel bottle with activated carbon filter cartridge, 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.
