Pac kit"s Freezable Mini Lunch Bag keeps anything you pack cooler, longer. Small but mighty, this mini cooler is sized just right for kid"s meals and adult snacks. It has a freezable gel built permanently into its lining and the entire bag freezes to keep contents cool. The gel-lined walls chill a small meal or snacks and a drink for up to 10 hours (depending on external temperature). While other bags merely insulate, a frozen Pac kit actually creates cold, eliminating the need for melting ice or bulky gel packs. Packet"s keep food cooler five times longer than other coolers which allows you to pack healthy foods such as: yogurt, milk, fruits and veggies. Uneaten food comes home still fresh and goes back into the refrigerator for the next day, which reduces waste and saves you money. Fold the Pac kit Freezable Snack Bag flat and store it in the freezer overnight (12 hours) to freeze completely for maximum performance during use. The new zip closure locks in cold, dry air and a buckle handle easily clip onto totes, backpacks or strollers.
