Tumbler Outdoor Vacuum Insulated Water Bottle 750ml vs 20oz TKWide with Café Cap, Tofu: which is safer?

Where these two actually differ

• We flag Plastic cap degradation and leaching and Bacterial or mold growth in seal on the Coleman and not on the Klean Kanteen.
• We flag Powder-coat cap degradation over time, Bacterial biofilm in cap threads and seals and Thermal stress on seals at extreme temperatures on the Klean Kanteen and not on the Coleman.
• The Coleman is Stainless steel vacuum insulation, plastic cap where the Klean Kanteen is Stainless steel bottle, stainless steel cap, which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
