August 28,2024

We tested the Thermos Stainless King Food Jar and found it does an excellent job of keeping food hot for hours on end.

A Thermos food jar that lives up to its name the Thermos Stainless King Big Boss 47-oz. Vacuum Insulated Food Jar combines big capacity with maximum temperature retention. Combining tough double-wall stainless steel construction with Thermos vacuum insulation this food jar keeps cold food cold for up to 24 hours and hot food hot for up to 10 hours. Durable insulating design remains cool to the touch when holding hot liquids and sweat-free when its holding cold contents.
