1990s Vintage Coleman Drink Lunch Camping Cooler 8Can Beige/Blue Throwback model 5274 vs Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid: which is safer?

Where these two actually differ

• We flag Unknown food-contact lining composition, Polystyrene foam degradation and styrene release, BPA or bisphenol analogs in exterior plastics and Microbial contamination if not maintained on the Coleman 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 Coleman.
• The Coleman is plastic exterior, foam/polystyrene insulation interior 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.
