Insulated 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 Waterproof coating PFAS status (non-PFAS assessment), Microplastics from material degradation and Waterproof backing degradation and leaching on the Hydro Flask 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 Hydro Flask.
• The Hydro Flask is neoprene-lined polyester exterior with waterproof backing 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 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 Hydro Flask grade, at 45% confidence against 82%, because it discloses less.
