We made them nice roomy so that you can fit many different brands of lunch box, drink bottles and containers inside. We’re also including an ice pack in it’s own sleeve that slips in the back zipper section under a mesh barrier to stop condensation reaching the food whilst keeping it fresh and cool for longer. They’re made from a durable canvas exterior with an aluminium internal lining with extra padding and an internal mesh pocket for small snacks. There is an internal and external name tag pocket, 4 rubber feet to prevent the base of the bag coming into contact with the dirty ground and a carry handle. They’re nice and easy to clean at the end of everyday adventures.
