Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs Prep & Go Insulated Lunch Tote: 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 OXO.
• We flag DWR coating leachables (non-PFAS) and Mold and bacterial growth inside insulation on the OXO and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the OXO is polyester fabric with water-repellent treatment, which is most of the difference in these two grades.
• The gap is 75 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 OXO grade, at 45% confidence against 82%, because it discloses less.
