Striped Freezable Wine Tote by PackIt has a patented freezable gel built permanently into the lining of the wine cooler bag and the entire wine tote freezes to keep a wine bottle chilled for up to 10 hours. While other wine tote bags merely insulate, a frozen PackIt actually creates cold, eliminating the need for bulky gel packs. PackIt keeps wine cooler five times longer than other coolers and is great for keeping wine chilled and refreshing. Fold the PackIt Freezable Wine Cooler Bag flat and store it in the freezer overnight (12 hours) to freeze completely for maximum performance. The zip closure locks in cold, dry air and a buckle handle easily clip onto totes, backpacks or strollers. PackIt is made from food-safe, nontoxic poly canvas and is PVC, BPA, phthalate and lead free.
