Thermibags are suitable for carrying Miniland solid thermos flasks and other accessories, depending on the size of the flask. The 600ml and 700ml formats would fit more snugly and the 280ml format allows you to fit a little more in the same bag. They provide an extra layer of insulation that protects from external environmental changes and, therefore, helps the thermos to maintain the temperature of its contents for a longer period of time. These coolers are made of highly resistant materials. The push-button handle makes them easy to carry in the trolley.
