Where these two actually differ
- We flag Microplastic shedding during heating on the Bentgo and not on the Klean Kanteen.
- We flag Silicone gasket degradation, Bacterial growth in vacuum seal and Surface corrosion under acidic conditions on the Klean Kanteen and not on the Bentgo.
- The Bentgo is Polypropylene (PP) plastic and stainless steel where the Klean Kanteen is Stainless steel body, silicone gasket lid seal, 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.
