We purchase these cambros to serve hot cocoa to Oregon HighSchool Nordic Skiiers & race help volunteers. They are terrific, keeping the beverage hot under etrememly cold, windy & snowy outdoor conditions for 6 to 8 hours. They allow us a hands free aproach to dispense a hot beverage with the easy pour lever function. We've filled these up with hot cocoa at 6 am, brought them to a nordic race in 10 degree weather and at 3pm the hot cocoa is still warm. Easy to fill, transport & clean. We're VERY happy with these cambros.
