The Momcozy Portable Breast Milk Cooler (22oz) is a travel-friendly insulated milk storage system designed to keep breast milk fresh and safe for extended periods while on the go. It uses a pre-frozen cooling tube that surrounds dual storage bottles, maintaining a consistently cold environment for up to 24 hours. With a compact cylindrical design and food-grade, BPA-free materials, it helps breastfeeding mothers store, transport, and organize expressed milk during workdays, travel, or outdoor activities. The dual-bottle system allows separation of milk from different pumping sessions, making feeding and storage more convenient and hygienic.
