This lunch box does not just keep food warm after you pack it up. It can cook your food and keep it at a safe temperature all day.

Perhaps the most important feature to consider is the actual insulation. Choose a lunch box with aluminum lining and foam padding for maximum insulation. This will give you dual protection from outside influences.


A key to a durable lunch box is to look for sturdy lining, double seams, and reinforced zippers. Choose a model made out of Oxford material for the highest durability standard.

Internal Compartments

If you need to bring a variety of foods to your destination, a lunch box with dual compartments will be best for you. You will be able to pack both cold and warm foods safely. However, a single compartment is best for the simple lunch of last night’s leftovers.


Will you need a plug for your lunch bag? Make sure you are traveling in a car with an adaptable cigarette lighter. Need to keep your hands available during your commute? Find a lunch bag with a shoulder strap.
