An insulated water bottle, often referred to as a vacuum flask/tumbler/mug/ thermos, is a modern marvel of everyday carry design. It is a container engineered to maintain the temperature of its contents for extended periods, whether you need your coffee steaming hot on a winter morning or your water ice-cold during a summer hike.
