Non-toxic freezable gel is built into the walls of the bag: the entire bag freezes! Fold, freeze, pack and go!

Simple to use: empty, collapse and freeze the entire lunchbox overnight (12 hours). By morning, the walls of the bag will be completely frozen and ready to pack. This lunchbox keeps food cooler longer, which means you can pack healthier foods that would spoil in other lunch boxes such as: prepared meals, salads, fruits, meats, and veggies
