The isothermal food bag by Fresk is the necessary accessory that you will need at school, on a walk or on an excursion because it will safely transport your meal (and your drink) keeping them cool (or hot) for many hours !
It has a large space to fit generous meals and drinks inside it, a pocket for your cutlery and a small tag to write the child's name so that he can find his ...guardian again in case of loss. 
You can carry it very easily , either by its small handle or on the shoulder hanging from its adjustable strap.
They are made from recycled PET bottles. 
They close easily with a double zipper and ensure that your food will be protected.
