Fulfilled by our friends at PackIt. Designed by Moms Who've Been There. Our Freezable Double Bottle Bag is the ultimate motherhood companion, offering safety, comfort, and peace of mind for life on the go. The freezable gel lined walls keep baby bottles chilled and fresh, while the spacious design easily fits two tall and wide 8 oz bottles and other keep-cool essentials. Hang it on the stroller handle for easy access or tuck it away in a stroller basket or carry bag. Our new antimicrobial and welded liner ensures leak protection and easy cleaning, making spills a thing of the past. And when the day is over, collapse it, freeze it overnight, and be ready to take on the next day’s adventures.. The double baby bottle cooler bag is designed with PackIt’s patented EcoFreeze® technology: freezable gel built into the walls of the bottle bag. The smart design eliminates the need for separate ice packs or gel packs. The Bag That’s an Ice Pack™: it’s freezable, it’s reusable, and it actually cools!.
