A large thermos filled to the brim keeps your foods (preferably with a very high water content) hot for a long time - there's less surface area per unit of mass to give out the heat. A food thermos works best with soups and stews with a high water content. Another cool idea for using a food thermos is to bring some ice cream in it fora summer time picnic or a visit to the beach. Before filling with hot food or water, it's wise to bring the bottle's inner walls up to temp by pouring in some boiling water, and letting it sit there for a couple of minutes, then draining and putting in your favourite food or drink. - Vacuum insulated double wall structure - Made of high quality, food grade type 18/8 stailess steel - Large mouth for ease of use and washing - The cap works as a mug - Side handle
