Our Tommee Tippee Closer to Nature Insulated Bottle Bags are intuitively designed for on the go feeding. Comes in one bag to keep bottles and food either warm or cool between feedings. Since they are individual bags, you can meet any on the go feeding need. Each has a sturdy VELCRO brand closure strap which allows the pod to be attached to just about anything, and they’re a compact size so they’ll even fit in a purse or shoulder bag.
