A new twist on the classic brown bag shape, the Freezable Rolltop Lunch Bag brings PackIt’s patented cooling to a rugged silhouette. Pack dairy, deli meats, fresh fruits and veggies without needing ice packs—the cooling is built right in! The bag's rolltop opening and secure buckle closure seal in cold air, keeping food chilled for hours. Thanks to the top-load design, it's easy to pack boxy containers. The Freezable Rolltop Lunch Bag has a slim profile when flattened that easily slides into backpacks and other bags for the ride home from school or work. More than a lunch bag, it's also great for chilling water bottles for sports and travel.
