This one comes in 6 different choices of adorable and stylish patterns, so you’ll easily be able to find one that you love. It has a silver foil lining for ultra insulation and will keep the contents cold for approximately 3 hours. That time will almost double if you use an ice pack inside as well. This bag fits 4 large 8 oz bottles and has a small pocket on the outside for your keys/wallet/phone. The handle has a clip, so you can attach it to a stroller, shopping cart, or whatever you need to attach it to, which means you won’t always have to be carrying it around yourself.
