Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs Daytrip Lunch Box YETI: 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 Microplastics from liner degradation and Bacterial growth in seals and insulation on the Yeti and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Yeti is Insulated lunch box, materials not fully described, 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 Yeti grade, at 45% confidence against 82%, because it discloses less.
