The Arctic Zone Pro Expandable Lunch Pack is the perfect lunch bag for a day at school, the office or running around doing errands. The lunch bag expands for extra capacity, allowing you to pack for long days when you need more food. The lunch bag includes a 4- piece container set with a sandwich size container and a snack size container. Both containers have lids and can snap together to be carried as one unit. Also included is a 650 ml Tritan bottle with Microban protection in the lid (excluding gasket) and a 350 gram high performance ice pack to enhance cold-keeping.
