Take up to six baby bottles on-the-go in Dr. Brown's space-saving Fold & Freeze Bottle Tote. This breastfeeding essential features a reusable ice pack that freezes right in the bag for grab-and-go convenience. Simply slip the cold pack into place, fold the bag flat and leave it in the freezer overnight (up to 12 hours). Breast milk storage is made simple with a zippered closure that locks in cool, dry air to keep breast milk, formula and snacks chilled for hours. The breast milk cooler bag simplifies travel with water-resistant material and an easy-to-clean interior. Each cooler tote fits six 8oz/250mL or four 9oz/270mL Dr. Brown's bottles. The included ice pack is removable, non-toxic and food safe. Available in black and multicolor geometric shapes.
