Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs Daytrip Charcoal 3 L Lunch Box Cooler: which is safer?

Where these two actually differ

• We flag Silicone gasket degradation, Bacterial growth in vacuum seal and Surface corrosion under acidic conditions on the Klean Kanteen and not on the Yeti.
• We flag Polyurethane foam off-gassing, Microplastic shedding from liner wear and Bacterial growth in seals and foam on the Yeti and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Yeti is Polypropylene plastic liner, polyurethane foam 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.
