The Marka Copper Vacuum Insulated Bottle features durable, double-wall stainless steel vacuum construction with copper insulation, which allows your beverage to stay cold for 48 hours and hot for at least 12 hours. The construction also prevents condensation on the outside of the bottle. Comes complete with the on-trend, durable, smooth-touching powder coated appearance and a screw-on, spill resistant lid and a durable, zinc-alloy hand loop. Fits most standard car cup holders.
