PackIt lunch bags are like a refrigerator on the go, chilling food and drinks up to 10 hours! The secret is theĀ cooler’s freezable gel liner. Once the bag is frozen, its walls generate waves of cold air that chill your food and drinks from all sides. All you have to do is fold the bag up, stick it in the freezer overnight, then pack it the next morning. The convenient buckle on the handle fastens easily to your kid’s backpack. Packing lunch for school just got a whole lot better! Get your PackIt lunch bag while supplies last at Mama Goose for $19.99.
