Cooler bags with an external compartment

External compartment

— additional compartment outside the bag, designed for convenient storage of small items such as phone, keys, cards, cutlery, napkins, or tableware. External compartments usually come with a zipper, Velcro, or clasp, allowing for quick and secure access to items without opening the main compartment where food or drinks are stored. These pockets can be made from the same thermal insulation material as the main compartment, or from a less insulating material, depending on user needs.
