Lunch bags are the perfect way to keep foods hot or cold throughout the day. Whether it is for a child or an adult, they are a convenient way to take food to school, work, a picnic, hike or road trip. Insulated with thermal foil, vinyl or Neoprene, the interior maintains food temperatures. Front or side pockets support water or soda. Exterior materials like canvas, nylon and polyester can be tossed in the dish washer or simply wiped clean. There are many different styles to accommodate various age groups and personal preferences. Some resemble a traditional brown paper bag, while others have a front flap pocket or zippered center compartment. Younger children may choose a design with a cartoon character, sports theme or colorful print. The most chic lunch bags resemble a purse and may even be monogrammed. Not only are reusable sacks good for the environment, but they stand upright for easy packing and flatten down for space-saving storage.
