Where these two actually differ

  • We flag Polypropylene (PP) additive migration and Bacterial or mold growth in seals on the Contigo 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 Contigo.
  • The Contigo is Stainless steel body, polypropylene lid/seal where the Klean Kanteen is Stainless steel bottle, stainless steel cap, which is most of the difference in these two grades.
