Kids Lunch Bag vs Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid: which is safer?

Where these two actually differ

• We flag Phthalates in polyester or PE, Polyurethane foam insulation off-gassing and Mold or bacterial growth in damp interior 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 polyester, nylon, polyethylene lining 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.
• We are less certain about the Bentgo grade, at 55% confidence against 82%, because it discloses less.
