Hot or cold, but not lukewarm, the Primus Klunken 0.5L Vacuum Bottle keeps your beverage of choice at the ideal temperature. This stout bottle boasts 18/8 food-grade stainless steel, vacuum insulation, and a screw-top lid to keep your water ice-cold or coffee piping-hot. Best of all, Primus finished this bottle off with a powder coat and cork lid to give the Klunken a rustic look and feel.
